Oh lord, the TDC thread.

So you can reuse your stock piston? Your'e just changing the cylinder? Or did I misread Nobrakes's thread?

 

In NB's thread his second pic shows a new piston.

 

Ahh, I see, says the blind man. So just the 300 cylinder and piston and new gaskets? Is that all? Is there a parts list somewhere?

 

Dunno, I'm learnin too. I'll keep lookin!

 

Part numbers:

1 x barrel p/n 11005-1983
1 x gudgon pin p/n 13002-1109
1 x set piston rings p/n 13008-1071
2 x gudgon pin clips p/n 92033-1054
1 x Head gaskit p/n 11004-1314
1 x cylinder gaskit p/n 11060-1740
1 x Piston p/n 13001-1463

 

But if you're going to the expense of the 300, why not go 331/340/351? Not that much more.

 

What are the costs of these upgrades.....just the jug and carb stuff......not including exhaust?
