Message: [QUOTE="SAPPER, post: 1367526, member: 99815"] We built the 100 to a 112 and everything is good except for one thing. It doesn't rev all the way up. It hits about 3/4 way to top but then flattens out. I can literally sit there and hold the throttle wide open and it initially revs up like it wants to hit over-rev then cuts back down and holds there. I tried jetting (stock all the way to 160 main), clip position, etc. triple checked all the PV actuating parts. It moves like its supposed to. I'm thinking it may be in the powervalve. I had the thick, flat slide cut back. Does the butterfly piece have to be cut as well? Or I may try to contact Eric Gorr and order one that way I know it's right. But he's closed for a month. PC makes one but $230 is a little steep. The bike flat out rips till it hits that point. [/QUOTE]
