Hey all I found out what happened to my motor.
FALSE TUNE! Had Idle gap too big.
Although I put a new motor in, I sealed it b4 i used it. I noticed that the sleeve is a diff color all shiny not dull and the top of the piston has a bronzeish looking top unlike the origional motor, the piston is gray all over. and the sleeve is like dark colored.
Which one is normal? Do you think I should contact SH and complain?
