Seeing as we've lost the original threads on the R6 throttle tube conversion I thought I'd start it again.

Cost: Around seven quid (though many thanks to Sudoxe for the freebie!)
Fit: Perfect
Ease of installation: On the naked SV, it's a pain in the @rse, as the bars have to come off to do it properly as there is less play in the throttle cables than with the standard tube and you have to slide the new one on after you've managed to get the cables attached (and what a bugger they were to attach!).
Result: Perfectomundo! After the rear sprocket mod, this has to be second. The bike is so much more responsive and the power comes on so much quicker that you'd swear you had another 10 BHP.

Downside? Nothing really if you've a smooth hand, apart from personally not liking the Yamaha grip as it's a little thicker than the Suzuki one, so I shall probably order one for the SV when I get around to it.

Now with my 46 tooth rear sprocket, 4 degree ignition advance and fifth turn throttle tube (as opposed to the standard bike's quarter turn), a clumsy hand will find it hard to keep the front wheel down in first, and it almost wheelies off the power in second.

So if you have a curvy - do it! :thumbsup:

Sounds good, It only took a few mins on the pointy/faired to swap over. Whoops..

So...jonboy...When do I get a turn? :lol: :lol: :lol:

I think part numbers would help, the R6 has diffrent tubes for the diffrent years.

I've just picked mine up, and wrote the part no. down, so still have it on a piece of paper at home. I'll post it up later.

Lifted off the svrider forum....

5SL-26240-01-00, comes with a grip.

About £11 ISTR.
This is an 03-04 R6 type tube and fits all curvy's without mods. Slight mod reqd. for the pointy faired, but unfaired needs no mods either according to the thread (might be wrong, ie. i, haggis, am not taking responsibility!)

jonboy

Yes it would have to as the bar diameters are identical as far as I'm aware.

No that's not an issue, I just couldn't get enough play in the cables and had to assemble the tube off the bars, which meant that the whole thing had to be slid back on, and this was impossible without removing the bars. Not a big deal, I just didn't expect to have to do it.

Ok if we are going to revive chat about R6 throttle tubes, then I will reiterate what I have said before too :lol:

……

I have done this mod to my curvy S and it is really easy to do, no extra modding required, just adjust the adjusters on the cables to take up/allow slack. I tend to think people get a bit over excited about the real world effects of this mod. I’ll give you the facts that I found out on a discussion about it and you draw your own conclusions!!

FACT: The stock tube requires 90 degrees rotation from zero to full throttle and the R6 tube requires 72 degrees. So you are gaining (loosing?!?!) 18 deg of twist.

If you were to put that in minutes on a clockface terms 18deg is equivalent to the angel represented by 3 mins!!! Yep that is it, 3 minuets (of a clockface) less twist, put your hand by your watch and simulate it …

3 mins ... thats it ... some people have made out that it ‘transforms’ the throttle behavior, some even saying it makes things over twitchy ... one word … ‘placebo’ (I so wanted to say BS there ) ……

Personally I think the noticeable difference is negligible!! When all is said and done, a R6 tube is ~£7, it does give you wrist that little bit more of an easy time, so my cost benefit analysis still says go for it … just don’t expect any transformations!!

jonboy
14-07-06, 10:12 AM
Well while not wishing to be confrontational I have to disagree completely. Look at it another way: the SV's throttle tube requires an extra 25% of twist to reach full throttle as opposed to the R6 tube — can't notice a whole quarter difference? Odd indeed.

The real difference is felt (as posted before) when you snap the throttle open (particularly in a low gear). This allows the fully open carbs to squirt fuel into the engine considerably quicker than if using the standard throttle tube. If you're just using the throttle gently, then I agree you'll likely not notice any difference.

Now, see how statistics can be manipulated?

If you like to rag your bike then it's the cheapest "performance" mod you can make; if you're not a fast rider then personally I wouldn't bother.

Personally I found the throttle is exactly as fast with either throttle tube, it goes at the speed of my hand. It's purely the comfort and the ease of using full throttle that made the difference. Not "fast action" but "short action".

jonboy
14-07-06, 10:32 AM
Yes but if your hand twists at the same maximum rate with each tube, then the R6 one will be 25% faster to fully open the carbs.


.

northwind
14-07-06, 10:36 AM
True, but your hand's faster than the throttle will ever call for so that doesn't matter. You can go from stop to stop in the blink of an eye after all. With the 1/5 throw throttle, you still don't twist it as fast as you could.

True, but doesn't that negate your point of both being equally as fast? One obviously has to fully open the carbs more than the other, all things being equal. The R6 does so by a factor of 25%, which IMHO is somewhat noticeable :wink: .

As nothwind said, it is the speed of the hand!! Also I feel I must point out that with CV carbs (like the SV and many bikes have), the throttle ‘butterfly’ doesn’t directly ‘snap’ the throttle open, this is left to the slider, which operates via airspeed and vacuum, the slider purposely operates slower/more controlled than a quick ‘flick’. So in short, you can flick the throttle wide instantaneously, the speed at which the throttle opens is controlled by something preset!!! So again as nothwind pointed out it is all about the ‘ease’ at which one can attain full throttle, not necessarily the speed.

I have purely added some factual content, I am not saying that the mod isn’t worth doing, just I don’t feel the overall difference in ‘twist’ isnt anything to get excited about and as explained above the massively quicker throttle response bit is welllll by definition of CV carbs …. Bull manure!! :D :takeabow:

I'm left handed.

But to throw my thoughts into the mix...

Its worth doing. I found a quicker action at hard acceleration from a slow speed (been side ways before I got used to it). But over all its a comfort mod, I now no longer have to move my hand to get full throttle which makes getting to full faster for me and more comfortable.

But as jonboy said - each to his own. It costs less then £10 so worth a try.

SVeeedy Gonzales
14-07-06, 02:27 PM
It's the comfort that's been good for me - no more walking my hand round the throttle to use the full range and less movement needed = more relaxed ride and can focus on the road that bit more.

Still no sign of a proper wheelie, but I've not done the sprockets yet...

kciN
14-07-06, 02:47 PM
I've read the threads and have one question.
How does it work!

Does the actual throttle part (where the cables reside) on the tube have bigger circumference, therefore as you twist, you get the cable moving quicker..??

It's something I may do, as it's a cheap comfort/mod thing!!

Jase22
14-07-06, 03:46 PM

Yes. All this does is enable you to get to full throttle easier, none of the other garbage. Just means less twist of the wrist to full throttle end of.

I don’t think it is a case of that, I just feel this sort of comment “Result: Perfectomundo! After the rear sprocket mod, this has to be second. The bike is so much more responsive and the power comes on so much quicker that you'd swear you had another 10 BHP.” Might lead people to believe that it is going to do more for them than it actually will.

From that statement, my expectations would be high, when in reality and after doing this mod myself remember, the performance difference is zero (not that I expected it too, again see above) and the comfort difference is small, but not irrelevant. So when all is said and done, it does make it that little bit less to twist, which is a bonus and therefore worth the £7 they cost.

I am actually going to modify my original tube to try and increase the diameter significantly and see how I get on as I feel even with the R6 tube, there is still a fair twist there!! :-k

So what, I'm selling it and misrepresenting something? Get a grip. It's my opinion and that of others as you can well read. If you have a lack of sensibilities and are unable to tell what I consider to be a major difference (yes major) then sorry, but that really isn't my problem. I was happy to let it rest with my comment above, but you don't seem to want to — odd.

We ran this on our race SV650's last season as it helped ease the pain of having to wind the throttle onto the stop by a double twist - if you understand what i mean!.

I have now got a proper quick action throttle which is adjustable.

The mod doesnt make the bike quicker or add any BHP. It just makes it easier to wind the throttle open..thats all.

Although do be careful as we have seen far too many road bikes with this mod that have been not adjusted properly and only open the throttle 3/4's full and dont allow it to be opened fully :wink:

Ohhhh easy there, have I upset you by voicing my (and others it seems) experience/opinions on this mod; just because they don't align with yours??

There is no problem you posting what you think, is there a problem with me posting what I think??

Or are the facts I have highlighted simply getting in the way of a good story here?!?! :lol:

jonboy
15-07-06, 11:33 AM
No, I don't mind people posting anything they like, however it's the way they post that counts, and if anyone was trying to manipulate the facts it really wasn't me.

The mod doesnt make the bike quicker or add any BHP

Obviously :wink: . However it does mean that the throttle can be opened quicker and therefore the power comes in quicker, and in this case 25% quicker, which makes the bike more responsive and have the appearance of being a little more powerful, hence my original comment of it seeming to have an extra 10 bhp in the first three gears (in MY opinion).

For seven odd quid, it's a great mod, which others have also agreed with. Now if anyone feels this ain't so, then fair dues, we're all entitled to our own opinion :roll: .

Today, I popped by the BMF Kelso show, and there was a stall selling 1/5 action throttle kits. Not proper quick action as SV650racer mentioned, just the wee slip-on bits of plastic that sell for £25. Very impressed by the seller

"What bike you got mate"
"Carbed SV650"
"Same throttle parts as teh SRAD that isn't it."
"Yeah... But listen, I've already fitted an R6 throttle tube, do these things make any difference"
"Ah... Well, to be honest, these are worse- they're a couple of degrees longer, they can be fiddly to fit and they cost 3 times more"

Have one of these (the R6 tube) on the K3 SV. Not got anything similar on the GSXR yet. Missed it at the nurburgring. By the time you've 'double' twisted, the other bikes have got a jump on you...

Well worth it for the money.

31-07-06, 06:51 PM
Did you try adjusting it at the carbs or throttle bodies(can't be arsed to check what model you have).

When I had it on my bike I adjusted for almost maximum freeplay(say 1/4 back from maximum) at the carbs. I then adjusted for required freeplay he throttle tube end.

Yep, and yep- in fact, it's easier to fit hotgrips to the R6 tube than to some sv tubes (the carbed one has irritating ridges on it that need to be cut off, the injected one I don't know). Ideal to do both at the same time.

jonboy
10-12-06, 10:38 AM
There really is no extra BHP, it just feels that way when you snap open the throttle in first and second. And I do mean that: snap it. If you're gentle or even just quickish with the throttle, you'll notice not a jot of difference. It's when you're able to get the throttle to fully open in a quicker time, that the power comes on seemingly instantly, giving the wonderful impression of being more powerful.

Worth it for a tenner? Oh yes.

Blue_SV650S
10-12-06, 05:06 PM
Arrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr ... How many times!?!? ](*,) :D … the limiting factor to the throttle opening time is the slider spring, orifices, engine speed and the diaphragm setup etc etc … the throttle isn’t directly connected to the sliders … all you are doing is moving the butterfly valves … you can whack these open instantaneously and it won’t make the throttle pick up any faster than is possible with the given slider setup …

If you have even looked at some CV carbes in action you would realise that the sliders move (reasonably) slowly and they are in relation to engine revs … the whole thing is certainly slower than even an arthritic granny could do even with a standard tube … #-o

The whole premise of a CV carb is that it prevents sudden opening of the throttle as this sudden change in pressure would mess with the carburetion … so it segregates the throttle butterflies from the sliders (which actually do the throttle regulation). All this tosh is just a fundamental misunderstanding of how CV carburettors work!! :roll: :roll:

Please please type in "CV (Constant Velocity) carburetor" into a search engine and read up on how they work before anyone else doles out any more drivel!!! ;)

FFS I know the difference it makes, so do others. It's most certainly noticeable. If you hate the mod so much, and if you think it's completely ineffective, then I take it that you've put the standard SV throttle tube back on, right?


.

northwind
10-12-06, 05:31 PM
I said this further up the thread, but that was months ago so I might as well say it again... For me, the "speed" of the throttle makes no difference at all to how I use the power, it's just easier and more comfortable to make full use of the throttle as the shorter action suits my wrist better, enabling me to save my right wrist for more important tasks. *

But, when you change things like this it's not always the hardware difference that really changes how the bike feels, it's the way you interact with the bike. Sort of like swapping tyres- almost everyone's happier on a new set of tyres, even though chances are they never found the limits of the old ones. Psychology in action.

So with this, it's not all about the hardware. It's about how Jonboy's hand and brain feels as he uses the throttle. And that's every bit as important as a hardware change.

IMHO the R6 tube would make the bike more enjoyable to ride, due to the fact that if while cruising with a comfortable hand position I decide to "wring its neck" I would end up opening the throttle fully. Whereas with the standard SV tube to open the throttle fully it would require me to reposition my hand to attain this.

I'm certainly going to try it.. not expecting more horsepower or even better acceleration, just a more comfortable and enjoyable ride.

Another thing I think would make the throttle operation more comfortable would be slightly weaker return springs on the carbs, has this been tried?

So does anyone have the actual part I need to order from Yamaha for my 2001 curvy? There's a right hand set on eBay at the moment but I'm guessing I only need the throttle grip.

8) In that case the R6 tube is for you, it does make it that little bit more comfortable to use the throttle, but we are only talking a few degrees here, so don't expect a massive change in rotation. Personally I'd still want less than the R6 tube, to make things easier/more comfortable still, but at least the R6 tube is in the right direction and cheap enough to do.

And for you it is making the bike 'pick up' notably quicker

Correct.

Some love it - some dont - for £7 its worth a go - THE END!

Yup, I'm with you there Skip, there really is nothing left to say. If Blue wants an argument, then let him feel free to find another sparring partner, as I'm seriously bored, now.

I am not looking for a argument??? But after trying to explain that what you are saying is scientific nonsense (and suggested you reading up on it), you still refuse to accept that by sheer design of a CV carb, it cant possibly do what you are suggesting!!!!! :roll:

Before you embarrass yourself further, Please Please read up on Constant Velocity carbs and how they work, it is an interesting, simple, but ingenious design that is actually there for preventing sudden throttle openings!!! 8)

1) Remove old tube
2) Fit new tube
3) Adjust cables
4) Get in a pointless argument on the internet about it.

The only things to watch, are that it's fairly easy to damage the screws that hold the control box together, and throttle cable adjustment's a bit of a fiddle if you've not done it before. You can do it all by trial and error if it comes to that.

My bad? :D

Have to admit I struggle to let it lie when people come out with twaddle like that and refuse to accept they might be wrong; even when presented with irrefutable evidence that they are!!! :roll: :oops: :lol:

It goes back quite a way I know, but if you read back you will find the dispute has only ever been over the results of doing the mod ...

I want to make it clear that if you think you are getting a performance upgrade, you will be disappointed ... what you are getting is something that will make riding a bit more comfortable (from a wrist point of view) and something that will make it easier to get full throttle position (again from a wrist point of view) unless you struggle to get full throttle with the standard tube, by design it WON'T/CAN'T make the throttle/engine response any quicker.

My other point is that you are also only getting a few degrees advantage, so it is not like the difference in twist is revolutionary. But it is a difference and it is in the right direction.

I have done it on 2 of my 3 SVs and will do it to my 3rd if/when I get round to it ;) ... but to be honest the difference in twist is not significant enough for me to loose any sleep over it ;)

Even those with minimal google-fu can find this (http://www.partsforscooters.com/Vehicle-Type/X6).

Those who possess a little more google-fu can find this (http://www.apexleisure.co.uk/acthrottles.htm).

I bought my last one from Fowlers ... http://www.fowlers.co.uk/parts/ one quick phone call and it's all done ... it arrived the next day .. think it was £11 inc P&P ... It'd have cost me the best part of that just in fuel to get it from my not-so-local Yamaha dealer!!! :wink:

They will look it up for you in 2 seconds, but the part number is 5SL-26240-01
