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)

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 :?:

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 ...?
