first off i want to say sorry so long but i want to try to tell all i have a 1999 stock, i just put pro circuits, jets 300, third ring on new needle,v-force 3,boost bootle, and uni filter. my problem is i rode it the other day for about 2 hours run like a top out running modded honda 450r, then all the sudden it started bogging on the top end and i noticed that the right side pipe was cool. so i put it on the truck and went home well the next day i went out to hopefully fix the problem but it wont start. i checked compression 120psi on both sides. checked spark good on both. so i got a spray bottle pulled air cleaner out sprayed fuel in the carbs and she started and run but only the left side blow a little smoke and pressure against hand nothing on right side except while squirting fuel in air box. took right side carb off and cleaned main jet it had some dirt in it but still the same thing so any help would be REALLY HELPFUL!!!!!
