wr400 compression problem
Posted July 26, 2009 - 06:00 AM
Recently found my wr400 00' model had no compression when kicked over, removed engine from bike and had it stripped down to find piston, rings and valves were well within tolerances. The engine was rebuilt with new gaskets. I then replaced the decomp lever cable as a precaution....The engine is now back in the bike but still no compression!!!!!! Please help im at my wits end!!!! Thanks guys:banghead:

It's like a valve sticks open for a while then shuts.
I kicked it once and it was like the decompression lever was pulled.
walked away came back later and it was fine again.
Has not ever happend again in over 4 yrs?

Sometimes, a valve will stick open and cause the same problem, just keep kicking and it should come back...

It may be valves or the piston rings...
