06' 450F Hard to Start
Scott Marks:
They swapped all the electrical components and no fix. So it has to be in the valve train. We need to check the flywheel keyway, pull the head and inspect the valves, & hears something to think about! Cams, the gear is pressed on the cam, could be the gear has moved.

Push starts and runs fine, but won't kick start doesn't sound like anything to do with the valve train, are you cracking open the throttle when you try to kick start the bike?? I not sure but I think these bikes have accelerator pumps on them.
Scott Marks:
It's all in the head! All 4 valves are leaking, 2 really bad. Looks like a new head & valves.
Scott Marks:
The Kawi dealer put in a new piston, rings, cylinder, head, & valves. Still won't start. Kawi tech support is going to talk with the engineers to see what they think. Kawi service guys think there is something wrong in the bottom end. Bearing, or crankshaft.
Will let you know.
hughes:
Are you paying for the new top end or the dealer or is Kaw.?? This is crazy what's going on with your bike.
