Jetting for T5/172

[H,POOL GADGE]

Orite lads, looking for ball park Jetting for T5/172, pm pipe. with am told a 26mm si/g carb, cud be 26mm px or 24mm px or g until i see it!!!

[soulboy]

on mine with proper t5 carb its got a 128 main and runs sweet as a nut ..that's with cut and polished crank and casings matched

[acko]

125 should be about right.

I wouldnt risk it on less than a 130 till its set up on a dyno

and dont forget it also depends so much on everything else ,not just main jet size .

thanx for you replies lads! question was for a bit of background knowledge as to were the jetting is on these 172's, as one of the lads has a problem when coming off throttle and stopping "it's cutting out"...i got him home with a bit of side of the road tinkering with carb, but carb tickover screw and air mixture screw were'nt adjusting throttle response as they can, could be flywheel seal, shite in carb/tank or this n that, i'll know better the weekend...

Now gadge
I got my main down to 125 after doin plug chops, and running 3 % oil, with a sip jl pipe.
I also had similar probs with it cutting out when stopping and coming off the throttle, ended up getting a 24mm Spaco carb which cured it.
