Hey all... Before I started this "little" project, the engine was knocking, making bad noises ect... The bike was ran on low oil for too long. I have ordered a new piston, rings, and head gaskets from the local Yamaha dealer. The piston was worn and scratched pretty bad.... and the rings were worn out. Now that I have all of the Top End apart... I was able to inspect the Bottom End a little bit. I was told by the dealer, that when this certain bike is ran on low oil... Its the bearings that usually go on them. The arm that attaches to the piston... There is slop in it from side to side. Is this the knocking noise I was hearing ???? or was it just the worm out piston??
BTW... I'm probably going to have the cylinder sleeve honed out by a professional... Its not nearly as bad looking as the piston was...
I just want to make sure I know what the problem is before I have to take the bottom end apart, which I am NOT looking forward to.
One more thing... this is my first bike, and my first rebuild. ( 1986 Yamaha XT350) Any tips and advice is appreciated!!!
