2004 Skeeter zx225 with HPDI.
Ive been trying to track down missing RPM's. At WOT im only seeing around 5400 RPM's, maybe 5300 if fully loaded. (All year, not just in heat.) Ive had my 25T1 prop re-worked and blue-printed. Filters didnt do anything. Prop shaft is 2.25" below the pad. Decided to sync my throttle plates, and see if they're opening all the way. Followed the service manual instructions to sync them. Pic is when the hotfoot is pressed all the way (Made sure the stop screw on the hotfoot isnt stopping it prematurely.)
Is that cam suppose to rotate further to where the white roller bottoms out? Throttle valves aren't getting to 90 degrees at WOT.
