I have a 2002 250ex that has a pro circuit t-4 slip on, 108main, and 4, 1 inch air box filters.
Now, my question is:
I am getting constant backfiring and popping when I let off the throttle under load and not under load. The engine runs fine and there is no smoke.
But the backfiring cant be good on the bike.
Has anyone had this problem? What size jets do guys run with the best luck?
I would greatly appreciate any help with this problem.
Thank you.
