Mine would bang from the primary when starting hot and would make a bunch of clanking when shutting off hot, basically all that noise means it is putting a lot of shock to your cranksaft. Yours does have the so-called heavy duty compensator already but mine after 10,000 miles is already banging and clanking once in a while. Under engineered junk but that is my opinion.
ok, thanks for the heads up. I do not have any of those symptoms when starting or shutting off, only the little rattle between 2k and about 2400 RPMs.
Will keep an ear out.
