KZ650B1 Crankcase O-Rings

#1 PostAuthor: r3sc » Fri Nov 25, 2022 5:18 pm

Hello,

Could someone tell me where the two 8.8mm o-rings, item number 4 on the diagram enclosed actually fit?

They’re not for the oil jets as they are 10mm.

I can’t find any mention of them in the workshop manual.

Cheers.

Base of the cylinder stud. Alleged to stop oil coming up from the crank case. Two of the case stud threads are open to the crankcase the rest are blind.
I've found thread lock to be more effective.
