i have a 1992 750 with a fresh engine that has 128psi in each cyl. it has a set of 4 psi pipes and no other mods that i am aware of. i was wondering if i should go up or down in main jet size with these symptoms......when i get on the throttle, exspecially hard, the motor seems to pop a little as revs get in the higher range, plugs look good and i never foul any. the sled is very rideable and other than the little miss or pop which occurs as stated, gose great. it is just a bummer whar drag racing with the buddys that it sucks. but i do not want to lose all the good qualities by tryiong to fix that one problem.
thanks Todd
 
Has the thing been jetted for sumer temps, or is it running the same jetting as it does in winter?
have you cleaned the carbs??

A POP IS NEVER A RICH CONDITION. THATS A LEAN SPOT. TWO THINGS YOU CAN DO FIX IT. UP MAIN JET OR CHANGE NEEDLE / CLIP POSTION WHICH I SUGGEST. 3:16 (yammie tony)
