01 yz426 clatter after valve adjustment Heyguys, I have an 01 426 that started leaking water into the oil. So I tore it rdown, replaced water pump seals, bearing, head gasket, base gasket, and while I had it apart new rings and valve adjustment. Now it starts first kick every time , no coolant oil mixture happening now, but has a horrible clatter coming from I think the valves. Had the thing apart many times now checking specs, and everything is by the book but can't figure out the clatter. Did not do it before I tore it down but now is driving me crazy. if anybody can help me out is really appreciate it.
