I would start with the richest so you don't blow your engine up.

Probably takes more time but is a safer way of tuning it if you're doing it by the seat of your pants.

Hmmm... before guys recommend me start from smallest.. so, I'm little bit confused. Really I'm going to fit jet kit, balanced card to avoid "detonating mixture" and after that check the result. As I understood smallest jet give more "poor" air-fuel mixture and how it can blow the engine?

Lean air/fuel mixtures (jets too small) can cause detonation and potential damage depending how hard you'll be riding it.

Rich jets will be safer to start with, especially since these jets are such an unknown.

Mate,

You just mess all... Now I don't know what to do... I have 123, 125 and 130 jet.

Carburetor guru - I need collect you opinion what do to...

PARUS you could have tryed all 3 by now just put the 125's in and see what you've got.
It's only a pipe and filter that you have it's not a race engine.

Go and read the factory pro set up guide its all you need!

I have TYGA maggot and K&N filter. Ok, will try 125

Hi Parus,

Did you ever get any positive results with the Kenso jet kit?

Its just I see they do them for the NC23.

Cheers

It difficult for me to compare because I haven't set of HRC jet\needles, but looks like they do theirs work on my race engine done by RLRMotors. I'd tried 108\105\105\108 main jet with Kenso needles and it was too lean. Then we changed them to 123 main jet from included set and it was significantly better. Now I run on 130 main jet, but looks like it little bit rich for the road use, because bike mainly run on the middle\upper middle range. So, the best choose for me would be 126 main jet, but with ram air or HRC air box it should be good chooice.

Cheers Parus.

I am just wondering if its worth trying a kit for my nc23. If you have got positive results with your nc29 then I may give it a go at some point

Yakama, unfortunatelly I have not dyno test for this and this only subjective feelings.
Will be appreciate if you send me any info. Are you going to use it for race purpose ?
