What do I do first? Snap and stalled.

I'd like to see a picture of that piston of yours

PIC request granted. I just need to get them off the camera and attach to my next post, but will have to wait until I get home from work.

First up is the piston with a valve growing from its top!

Another shot of the piston.

The head that was beaten down!

Another head shot. Can anyone tell from looking at the valves if I was running too lean or too rich?

Here is the condition of the coils I found to be amazing. Consider the fact the this bike ran remarkably well even with monster cracks in the coils!

A better question is, how many rpm were you turning when the valve let go? That motor did a lot of revolutions with the valve bouncing around in the combustion chamber :woohoo:

On automotive engines I have seen them bounce pieces back up into the intake and then into other cylinders, one valve taking out three or four cylinders

im impressed!:evil:

Somewhere around 5000rpm. As soon as it blew it stalled and I pulled the clutch but where talking approx. 83.3 revs per second. So...."Bang! what the hell was that? (realize engine stalled) pull clutch" Estimate 1.5 seconds, revs 125.6. More than enough to beat the crap out of anything or anyone!LOL
I also noticed a sloppy primary drive chain which I'm suspecting was causing my rattling noise that would change when idle and pulling the clutch. I didn't know of course if the noise was normal or too loud because others have posted that these engines are a little noisey. Maybe just not as noisey as mine was.
As far as the coils. Can anyone suggest a good replacement?

Wow, Definately way rich in METAL. Thanks for the pics, that is awesome.
