Hi all,
I did some mods to my bike(xr650) and i'm afraid i've screwed it up. I read an article on "uncorking" the xr650, and did what they said to do, take airbox restrictor out, remove baffle, rejet, all that. the thing I was worried about was the jetting, but it ran PERFECT when I rejetted, so I never thought twice about it. Anyway...been riding it for a few months now uncorked, and this morning when I went out to ride it was making a knocking noise. I tried to pinpoint the noise, and I think its in the cylinder. I rode in a good bit of mud last week, but I washed everything off really good and made sure not to get any water in the airbox or exhaust. Any ideas? I'm guessing i'm really screwed if it's a knocking piston....ain't gonna be cheap. I tried to listen, and it sounded like I might have heard a snapping sound after I had already heard the knocking as well, but it's hard to tell since I can't ride on pavement. Please help!
