Hi Larry
Now how did that happen? Find any thing else strange during the teardown?
Take care and ride safely dear friend
Yours Hank

I'm guessing when i made my own custom variator to handle the power, I'm guessing more of the stresses and pressures were transferred to the piston, because the variator and belt didn't break... Just a guess but there's really no sign of anything hitting that piston..
Every thing else looks pretty normal...

dang that's kinda cool actually, I guess that means you've got some serious compression/combustion going on!

looks like you where running lean to get the piston hot enough for the compression to reshape the piston

Too Much Vacuum in the crankcase.
Put some compressed air in the vent Hole.

OK the verdict is in and it's not good.. Fawkes sustained more damage from that thin oil i used than I first thought. I'm afraid the stroker crank sustained damage, so Fawkes is way worse than i suspected. A top end rebuild is not going to be enough it's going to be a total rebuild.

 Ouch! That sucks. What a beast in his prime. What are your plans for the rebuild? Same setup or going to try something different?

Not sure quite yet, this really was my fault not the strokers, I knew better than to use that thin oil.. I needed to get to work, and fawkes was parked outside in the winter, This is my fault... I think for now Ill buy a scrappy engine, to get going again. then spend the summer rebuilding this one, And this time taking my time to do it right. Don't worry the Beast will be back |

Sounds good to me  Don't beat yourself up over it, stuff happens, I've blown many a motor ;D Can't wait to see the Beast return. Best of luck, long live Fawkes!! |

Ok Here's the Plan I just bought this engine from scrappy.. GY6-100 complete engine, 50mm  Ill take my Big Bore head, HP cam, performance exhaust, short shaft and gears from Fawkes and put them on this. Then Ill rebuild Fawkes old engine with a new stroker crankshaft.  |
