ok, now i'm lost. i've checked all screws, reviecer is cushioned with double sided tape, wires aren't crossed or wrapped in any way, brake discs and all are fine. i can't figure out what the heck is going on. I ran it this weekend, leaned it up a little (finished with break-in) and it got a little better, not as much glitching. i didn't notice before but the throttle is also glitching when i get to the higher revs. i have been reading about the tuned pipes... could the sound frequency cause the glitches? any more suggestions? if needed, i'll record some video of it glitching if someone thinks it'll help figure it out. Thanks for all your help so far!
