Hey guys, I recently rebuilt a kx450f from the ground up, after I rebuilt the motor I turned it once or twice to make sure all was good and it sounded fine perfect. After I installed the engine back in the bike this grinding noise came up, sounds like it’s coming from the piston, I put new crank cases from Kawasaki, crank bearings/ countershaft bearings/ transmission bearings, All new seals, hot rods crank and rod, wiseco prolite piston, new timing chain, Hinson clutch cover on a stock clutch and a boyesen supercooler.
Just pulled the valve cover off halfway through typing this
And the noise stopped, put the valve cover back on and it came right back.
Weirdest thing ever, anyone heard of this before???
