Condolences to you and your family Mike. It would seem your mechanical talents are hereditary.

LMAO, you can change 1/2 a ring by pulling clutch, and the primary drive link. ..wow!

Pull the oil pan and you'll find the rest---- bottom end failure

Bill/BentON Racing · « **Reply #607 on:** November 17, 2016, 03:54:02 AM »

Yep, it's next.

The Butch Pace bad temper one! Ex guide is fine ,pulled pipe. Life has been a zoo since I got home. Cylinder wasn't cracked in early pics!

Looks like more of the piston in there. Make sure not to lose any of the pieces!

Bill/BentON Racing · « **Reply #617 on:** November 17, 2016, 09:58:59 AM »

It's ok, cause I'm ok, thank God! Won't be repeating this one....Engine noise is Engine noise! My bad. Jim, get the welder fired up! LMAO, Bill Oh, Scottly. ...buttons, I'm getting old, lol. Looks like light weight pin broke!

kmb69 · « **Reply #618 on:** November 17, 2016, 10:13:09 AM »

That's some real carnage there!

madmtnmotors · « **Reply #619 on:** November 17, 2016, 10:46:33 AM »

I'm curious to see the #3 combustion chamber...

PeWe · « **Reply #620 on:** November 17, 2016, 11:05:55 AM »

WOW! Look like a maniac meat grinder went wild! Not much left to reuse, right? Crank and rods are gone too? Head + cam OK?
Thin piston pin caused it?
I'm curious when I have my engine apart, will grind upper case for bigger bore sleeves, file pistons ring gaps for 71.25mm JE pistons this weekend. German prim chains, std tensioner and Ape ultra crank... If there is anything to be aware of to protect the goodies going in.

No problem with cam chain + tensioner? My metal upper wheel w cogs had marks after cam chain.... 500km max.... std tensioner goes in next time.

No personal damages most important here! NOS old man parts difficult to find.

Bill/BentON Racing · « **Reply #621 on:** November 17, 2016, 11:35:15 AM »

Not sure if I am! Lol

Jerry Rxman Griffin aka MuthaF'er · « **Reply #622 on:** November 17, 2016, 11:43:21 AM »

Did it drain the oil tank too?

dragracer · « **Reply #623 on:** November 17, 2016, 11:43:55 AM »

I hate being right sometimes.

bwaller · « **Reply #624 on:** November 17, 2016, 12:12:45 PM »

Man oh man, a knock is a sign of trouble alright but how long did you run it when it started coming apart? Wow Bill is there anything good left? Any gearbox damage, cam ok?
