Engine or clutch sprockets

Post by Bob Alexander » Mon Jul 15, 2019 10:20 pm

Rummaging through my parts box today and found these sprockets. I don't remember any clutch or engine shaft with protruding cut that would accept these sprockets. Has anyone else seen one? Thanks...

Straight bore? Bore size?

From my memory without digging there was an direct drive deal that went on the crank & gear locked into it by simply tightening the nut. it was mainly used on direct drive karts for "quick" / easy gear changes. So you only have half of it! Keep digging for it's mate!

Rob - Looks a bit like the old Tabloc clutch sprockets ?

Nope! I have or had some of them. They slid into a slot on the back of the drum.
