I dont know anything about this K+B motor..It has a wierd drive shaft that threads out like a stud.
The stud was a standard K&B thing, if it's bent it's cheaper to replace than a crankshaft.
The whole Sportser series .20, .28, .45, .61, 1.00 were built to be cheap to make, special aluminum with hi silicon content made it so the didn't need bushing or sleeves. I had a few, none where very good, you got it at the right price
