GP800 wont rev over 4800rpm
I brought a 1999 GP800 as a project, have done a full rebuild on engine .75 oversize.
For some reason it wont rev over 4800rpm even on the trailer, i have been told it was a hire ski so im wondering if it would have a limiter? it jumps outa the hole and gets 38mph @ 4800rpm i cant fault it apart from the low revs. I am running 40:1 premix and no oil injection, new plugs, spark seems fine, plugs are a little black but that should of been the assembly oil burning off. powervalve servo is dead but i have disconnected it and have tried opening pvs manually but to no avail.
