ENGINE WENT BANG
Posted: Mon Jul 22, 2013 1:16 pm
Just bought a ZXR400 (think its an L3 on a 1993) model, it sounded like it had a cam chain rattle/incorrect valve clearances etc.
Anyway got it home after doing a round trip of 550 miles, started it up!
Only firing on 2 cyclinders which explained the rattling, anyway I got the other 2 cyclinders working (could tell by the sound of the exhaust and no rattle - and all 4 pipes were hot) it went bang and immediatley stopped.
Turned engine over by hand and imagine that the socket bar was at 12oclock, it would turn to 6 oclock then stop again, back to 12oclock then stop again.
I think its dropped a valve and bent it, cams and chain still look ok and so do the valves (from taking off the rocker cover) just wondering now if its someting at the bottom end like a bolt sheared :smt013
Will post a video on you tube of my findings and let you know what I find it was.
NOT A HAPPY BUNNY
