Hey PM.

Going to install a stroker this weekend.
New clutch springs and discs as well.

It's pretty straight forward.

But I don't know what the hell this little piece is for or where it may go. It came with the stroker. Any ideas?

Its like a half circle? Woudruff key holds the flywheel in place. There's a machined slot on the ignition side of the crank.

Good stuff TP. The unknown piece fits into the slot at the front of the crankshaft where the flywheel goes. There is a groove on the inside of the flywheel that lines up with it . It basically prevents the flywheel from spinning on the crank.

I guess there is a wood piece in there already?

This other one must be a spare...

Thanks Tmas

Yep looks like you already have one in there. You're gonna love that 108. The stroker crank makes a huge different with the low end torque.

Alright pretty much done the install.

I have noticed that the 51mm stroker has side to side movement. The flywheel to the clutch basket theres about 2-3mm of free play.

Not really a big deal. This link also talks about the 2-3mm of free play.
