my 2000 still burps when i whack it (hehe). when i am riding i can pin it and it goes fine but at idle it will bog. is this the mixture? i dropped the needle 1 clip and it did get better. i was afraid to go two clips so any suggestions? ekp clip 4 from top 48 pilot 100 pilot air 170 main this was suggested by J.D. and has worked ever since, i just wondered if i could get it gone altogether. by the way, BK mod (didn't notice anything), airbox lid gone, pc t-4 exh, yz timing, no gray wire, no throttle stop, and ride at 0-50 ft elevation 90% of the time. 0-2000 on the occassonial trip.
