Ignition timing

[redmandan]

Thanks mate! I think my logic is sound I just wanted some confirmation.

I've had the head off a Yanmar marine diesel engine before but its easier when you're going to go +-10mph on a sedate river jaunt vs 70mph+ on 2 wheels!




I realize that smashing a piston into an open valve is probably the worst thing to do so I made sure to turn the engine over many times by hand before I buttoned everything back up. I had to anyway to check the valve timing.


This was all because I hated the tin can rattle of my top end and the most likely diagnosis was a worn cam chain.
