View Full Version : Dynojet 170's
Where is the best place I can get these from, for service and price? Also never done this so I will have a go and stick a picture guide on me web page when I have done it.

I've heard pdq (http://www.pdq1.co.uk/) are the place to go.
£82.50 is this a good price for a Dynojet kit.

I got mine for £20 :) But it sounds about right for one that's still got all the jets in...
PDQ gave me brilliant service for buying jets, arrived next day by first class post, and I didn't even think that was possible! Price, for jets, isn't likely to matter all that much, they cost a couple of quid so it's worth gpoing for good service instead of shopping around to save 10p.
See I've already got the BMC filter, so I just need to get the jets, would there be anything else i require apart from the jets?

Heh, I like that your sig now has "BMC filter and rejetted" while you're still shopping for the bits :)
You did get the Race RS, didn't you, and not the Race? If so, all you need is the it and the big-ass jets. Well, all you need is the jets but to do it well you need the kit. I'd probably get 165s and maybe 160s as well were I you with the slip-on...
Cheers dude. :lol: Oh yep I am still shopping, I havn't even seen the new powder coated wheels and the calipers yet, they are being done this week, I will pick the stuff up on Saturday when I fly back to the uk. Just saves me doing the Signature then, I am in a bloody hard Cisco Content switch course, which is way over my head at the moment, so I have time to go on the forum.

Give Big CC Racing a call about a dynojet kit - I paid about £65 for mine if I remember rightly...

that's just the Stage 1 kit they're advertising... Going by the directions in the Stage 1&3 kit, which I got, it won't include the stiffer springs or the #54 drill bit to drill the slides, just jets and needles? (Dynojet recommend you only use those parts with pod filters and no airbox, but since they recommend you use 144s (IIRC) with a full system and race filter, I'm fully prepared to ignore them and just use their bits.)
The DJ kit's actually really badly specced... Their recommended jets are kind of wee, and it includes 138s but nothing between 146 and 180! My bike wouldn't run on anything under a 155, with nothing too out of the ordinary in it...
I know that Mike1234 was selling some carbs with 170's... for about 120..

But there sold.. though I think he might be able to get some more.. though he does have them with:
Carburettors
Supplied with 137.5 and 142.5 Mikuni jets
£60

Mike's carbs would have been great for someone doing it from scratch, definately... 6 months ago I would have had his arm off :) But the jets in those are waaaay too small for a setup like sexysi's...

so it's a BMC Race RS and a Renegade Full System or just the End Can?
I'd have them but I ain't got 60quid to spare at the moment, had to get a new shock. Plus I need a oil change and on the forks to..
so it's a BMC Race RS and a Renegade Full System or just the End Can?
Reni end can
Its a BMC Race not RS but I desnorkled so its identical now to the RS (same filter elements etc). You will therefore need to rejet!

Doh! Have a search for some of the very long discussions with Mr. Charnley on this one.
After the last, er, debate I actually compared a Race and an RS sitting next to each other. They are very different and I even contacted the representative from BMC who assured Andrew that there were no differences and he admitted that there had been numerous revisions and he couldn't actually confirm that they were the same.
What jets do you have in there at the moment? I've only used 165 and 170 jets with a full race system. Are you sure you wouldn't be better off with 155s or something?
Mike bearing in mind that the carbs and the setup is standard, then I'm open to any advice. The filter I have bought was from a guy on this forum, so I havn't even seen it.

Hum.... Well, cutting the top off the Race should give some benefits, just like doing the same for a K&N... But like me and Mike have said, you probably need to think smaller for the jets.

So if you haven't got the filter does that mean you are buying it already hacked about or is it still as new?
If the filter hasn't been hacked about then my advice would be to put it in as is and look at putting in some larger Mikuni jets, probably 140 or maybe 142.5 - I doubt you would need anything bigger.
Have a look here (http://vmaxoutlaw.com/tech/dyno-mikuni.htm) for a comparison of Mikuni and Dynojet sizes.
If the filter is already molested then I'm not sure what to suggest as I was unable to get it to work properly with the modifiedone I tried.
He's bought mine. Remember it was BMC who said its identical to the RS when desnorkled, so lets not start that up again.
As you all say, he's going to need 165/170's. I had 165's before I went back to standard setup and it wasn't quite right at top end. I'd go with Mike's setup of 170's.
Out of interest Mike, did you desnorkle and remove the entire top (making it into an RS) or dremmel the circular snorkle bit?

With a slip-on, he so doesn't need jets that big... I'm running 165s with a race system and it works well, though perhaps the 170s would be better- it was going to the dyno before I broke my hip, but that'll have to wait. Mike's 170s were for the same, IIRC...
And like Mike says, BMC have contradicted themselves on the question of whether it's the same. I'd take Mike's word, having compared them himself, over their uncertainty any day- if you contact them most of them don't even know what the Race RS is...
Last time you posted on your own mods,Andrew, you complained that there was no point in doing the mods at all and that it'd never feel right... Now you know exactly how to set up someone's bike? From the start, just about everyone advised you that 170s were too big for your twin Renes, which are probably less restrictive than a single Rene...

Not sure I understand what you are asking. We cut as big as hole in the top as we could without destroying the actual filter material.
The interesting thing was that it was impossible to get the hole as big as on the RS because the filter material itself was wider!
This fitting of new jets, can this be done, without taking the carbs out, or is it carbs out on bench and do them in the warm. Probably going for the 140-142.5 Mikuni jets as Mike suggested.
Also places to get these things any ideas?
Last question with the jet kits do you get all 3 jets, or is it just the main jet that you change?

Just change the main ones and don't overtighten them!
Need to take the carbs out I'm afraid.
Yeah, you should have bought my carbs that were on eBay last week :D

Having read Andrew's post again I think there may be some confusion as to what constitutes the BMC Road, Race and Race RS.
Here is a picture of the Race RS:
http://www.biketrackdays.co.uk/forsale/DSCN1365.jpg
The Race has a thicker filter element and the top is covered bar a small hole in the centre.
I assume that the Road one has a snorkel similar to the stock one but it may not. I have never seen one.
So from Andrew's post I have no idea quite what is being removed by the Dremmel or anything else.

Just ordered 2x142 Mikuni jets for me carbs = £8.00
So I am happy. Cheers guys

Yeah i've got 142's in mine with a rene kit, should be ok for twin rene's I should be getting soon :D
Did you find it an easy job removing the carbs and fitting the new jets, I take it the torque setting for the main jet is in the Suzuki manual.

Viney did it for me at the time but yes its easy to do, now i know where they are etc, i'd happily do it myself

Can be tricky to get the choke cables off, and the screws that hold the base of the carbs on are b******* as well. Have an impact driver and decent molegrips handy I reckon, and (as Viney pointed out to me when I was giving in to frutration) the chole cables can be removed from the control end if you can't get them off at the carbs.
All the fasteners are extra-special buttery phillips-head screws, and they really are rubbish. so be careful.
Other than that, it's pretty simple.

You are joking aren't you? Please say you are... So you mean you have a hacked about Race rather than a standard Race or standard Race RS?
Aaaaaagggggghhhhhh!!!!!!!
:lol: :lol: :lol:
yes viney had to impact driver almost every screw :wink:
I reckon that i could get the carbs off, rejetted and back on in about 30 mins now...done it sooo many times :roll:
things that i have learnt when taking carbs off.
Remove choke cable from lever end
Remove throttle cables from carb end
use a decent screwdriver on all screws, then whack with an impact driver
Dont over tighten the jets, finger tighten, then pinch up with a screwdriver.
Fit a tube on the front carb for balancing purposes
Contact cleaner is the best stuff in the world for cleaning carbs
dont drop the carbs down and break the heaters!
Other than that, pice of pie :D
