Strange noise at high rpm and very low power.

[QUOTE="crashing_sucks, post: 1209083, member: 74634"] Interesting, might be a timing issue. I pulled that cover off on the resonator and found that it let exhaust into the resonator box at idle but almost immediately off of idle, (feels like 3-4k rpm but that's a WILD guess) the valve slides shut and exhaust stops coming out of that port. That makes me think the KIPS is working, but maybe the timing was off? I didn't even know the timing was adjustable until you mentioned it but it did strike me as closing pretty early, almost as soon as I flicked the throttle. Air filter was clean, airbox lid was removed so intake doesn't seem to be the issue. I was thinking I'd repack the silencer and if that didn't help things I'd tear into the top end. [/QUOTE]
