Pioneer 620 - Won't rev up clean to full throttle

[cdahl383]

Ran up to the hardware store this morning and got some stuff for the flywheel puller. I have this bigger puller that's sturdy but the slots/bolts that came with it are too big for the little bolts that thread into the flywheel. Got some spacers and washers and nuts for the three bolts that go into the flywheel. Now they fit into the puller really well.

Got it set up and sprayed some Kroil on everything to help loosen stuff up a bit. Will try wrenching on it later today. Hopefully it will come off without too much trouble. But I doubt it haha! I made sure to put the nut on the end of the crankshaft too. A buddy of mine forgot to do that once on a dirtbike and attempted to pull the flywheel using a puller and he mushroomed the threads on the end of the crank. Not good!

That'll work. Tighten the puller and pick the whole mess up by the puller threads and hit it with a hammer. Ought to pop off.

Presumably, you've grabbed all the available threads with your little bolts. I think one time in 15-20 years I had the threads tear out of the flywheel.
