Hi guys, my 2002 800 rmk has a terrible bog/distortion at high RPM (7000-7400) when you crack it open. If I play with the throttle I can get it to pull at 8000 but it just doesn't seem to be pulling as hard as it should.
VES bellows/stainless valves are clean and OK. I have never changed the primary and team secondary springs (only bought it this fall), so not sure if that would be a good place to start? Compression at 143/147 and new plugs. I rejetted from 540 mains to 500's...needle on #4. Primary has 64gram weights. New bottom end w/wide bearing, line bore and primary clutch balance done 100 miles ago.
My elevation is 1800' and being in the prairies I run a wide range of temperatures! If springs are where I should be looking what colors are recommended for a good setup? Also, the premium light doesn't seem to work, but flashes at idle regardless of key position till revved up then completely out??
Any help greatly appreciated, I'm lost on where to start!!
