I've been having problems getting rpm up. so I finally let it rip on the stand. Runs up to 7500 hard and hits a wall. Like it has a rev limit. I found a smart valve stuck and removed both. Same result, 7500. Shortened center distances ( maybe the belt is too short) No, thats not it. Then all of a sudden, 8200 and it hits a wall there. I would think on a stand I should be able to run it up to what ever my nerves could stand. Any Ideas?
