Timing Retard Eliminator. Do They Work?

[tonny006]

i have just found this on ebay.
Has anyone used one?

Don`t bother , the SV has very little Retarding on it , unless you count me on a bike :D

[Mr Speirs]

Is this an old post just copied and pasted? :)
Yes they eliminate the Timing Retard but some people contest that the real world benefits are negligible. Also you can do it for free using nothing more than a small screwdriver and tweezers or a pair of snips.
If you do a search for TRE it will lead you to a good step by step guide to getting the same effect for nothing.
I have done it myself but haven't noticed a marked difference in performance but like the knowledge of knowing each gear is being fuelled properly

Has anyone actually tested it in an empirical fashion? Most folk say it's not worth doing, but some seem to swear by it.

[Mr Speirs]

One fella on a previous TRE do they work post actually dyno tested an SV650 with and without the mod and test revealed that it made no difference whatsoever.

It wouldn't suprise me if it were zadar... and no... the TRE's make such a small difference it isn't really a performance item, certainly not worth the money the pre-built TRE's are sold for.

[xXBADGERXx]

It`s a perception thing , people swear it makes a difference as they tear open the throttle to "test" it , in reality , it makes little to no difference , save the money and spend 30 quid on a useful item like an oil rad guard or Fenda Extenda :D

[yorkie_chris]

Or even do it... but for f###s sake do it properly with a resistor worth about 6p for the same effect...

[xXBADGERXx]

There is that too :D

[boo86]

you can do it for free ( i have on mine) cut the wires coming out of the gear possition indicator. only the green and red, the others are for the nuetral light. Then the bike doesn't know what gear it's in and therefore cant retard the timing in 2nd and 3rd.

strange this should come up today.....

i done this last night....

some people say there is no point...some say it works (I done the 3 minute DIY Job, NOT that piece of **** thing u have linked too)

I asked about this a while ago (also searched and read up about it)...at the time i decided not to do it as no point it seemed and I had no confidence in doing anything to the bike...

my confidence is now more so...so i thought why not, id rather do it (and see no difference/not harm the bike. than not do it and always wonder....)

now then...i dont feel any major difference myself...it does seem a bit smoother and does SEEM to pull a bit better at top revs in 2nd but as said before i think this could quite possibly be percieved rather than actual.

personally the way i did it is the same way as in the link boo86 has provided above....as i think its the easiest way....
there is also another way at www.sv650.tk (http://www.sv650.tk), click enter site, click "mods" and there is step by step there but doing it under the pillion seat rasther than the tank...same thing just different place....

so in conclusion....IMO do it the DIY way rather than always wonder (as its not going to harm the bike anyway) but DONT buy that rip off piece of kit your looking at!!

[boo86]

I agree with dappa.
I race mine so my thinking was if I'm dragging down the back strait of Croft. I havn't done mine the other guy has.......... I'll get left behind. Even if I get into tower 1 meter later than him. It's more work I've got to do through the Jimmy Clark esses.
It's only there to retard for noise tests. It does decrase power so get rid of it. FOR FREE

[tonny006]

Thanks for all the replies,
I would like to do it but all the bikes pictured are earlier models than my K5.
Is it done the same way?

[Dappa D]

oh yes...apologies...didnt see your signiture...sorry fella I dont know!!

[boo86]

have a look at the gear possition indicator. Then have a cup of tea and think about it.
If the bike doesn't know it's in 2nd or 3rd how can it retard in them gears. All it knows is it isn't in neutral, 2nd or 3rd. So it assumes it is on 4th or 5th or 6th and runs the best map.
It works like binari. Am I in 1st = 0, am I in 2nd = 0 am I in Nuetral = 0. Therefor I am in 4th or 5th or 6th. The ECU makes the decision to run default ignition map.

[Mr Speirs]

I believe with a pointy there is a resistor involved also. Dont know where it goes or what value but Im sure yorkie_chris will be along to help soon.

[Dangerous Dave]

Not all this crap again.... :smt092

Wouldn't waste money buying the product and I wouldn't waste time DIY'ing it either.

The SV650 is only very slightly retarded, there are no gains to be had other than the imaginary butt dyno thinking otherwise. It has been proven and tested so many times, it makes no performance increase!!!

The products (G-Pack, etc...) are aimed at bikes which actual do have a lot of a ignition retard, the problem is the product list lists the SV650 in its fitting guide and everybody reads the hype and product blurb and instantly beleives it will do the same to their SV650. This is utter rubbish, the product description/blurb is aimed at Hayabusa's, GSXR's etc, not a SV650!

Countless tests by proper SV650 tuners have proven it does not work and the people that say it does state the same thing "I fitted it and went for a ride a felt a real difference", this is your imaginary butt dyno telling you you have just increased the power by 10bhp because you fiddled with something!!! Utter rubbish....


Sorry, rant over now and I am climbing back into the straight jacket.
