00' wr400 cylinder damage
Posted March 24, 2002 - 10:17 PM
The piston and cylinder are scored about an inch wide, due to rings melting. The only other noticeable issue is a bit of bluing on the cranks, right next to the rod. Is it possible to rebuild with a 426 piston,cyliner and rod? All of this could have been avoided with an ignition cover guard! I'm sure happy that Yamaha waited until 01' to figure that out. Thanks for any help,tim

what oil were you running, when was it last changed, how did you realize the cylinder was scorded, and finally, good luck with the fixes.
