t5 172 malossi standard carb and sito plus

as i pull away once the motor has been running for 15 mins there is a stutter as if ive hit the kill switch then it picks up with a jolt. it feels as if its between jets.

now and then it will give a backfire noise but not a bang but more of a release of pressure noise like a woopey cushion in the exhaust or air brakes.

when the engine is cool its ok though. is this an air screw issue?

any thoughts apretiated. (yes ive checked there isnt a woopey cushion in the pipe)

As this is doing it once its a bit warm i would be thinking pick up..my old 172 had the same symptom but im sure thete are better people with better ideas on it maye

i let it cool down and two hours later went for a spin and its crisp as anything again. ive been riding bikes so i cant judge if it feels fast or slow as my judgment goes a bit sque-wiff but its definately sluggish and hesitating when hot.

ive got a nos stator so that can be changed. is the puller the same as a p2 ?

any more thoughts would be apretiated

yes puler is same pal...mine was ok when cold it was just when warm but it could be anything electrical ie,plug,cap,ht lead,cdi

new coil, new stator, cleaned carb, adjusted air screw but it still farts if i de exelerate with the throttle closed then open it to 1/4 again.


it poppes out of the exhaust still.

help

have you had it dynoed ,does it really have a T5 carb on and not perhaps a P200 one ...as the slide itself is different and makes a difference ...?

no not dynoed, train driver is going up to diablos soon so i may tag along.

how do i tell the differance between the p2 and t5 carb?
