64 ish Kawasaki B8 125 - Looking for piston rings!

Hi all!


I am assembling an engine for a 1964-65 B8 125cc road bike.
I have a new 1.5mm over piston but need rings. I broke the top ring on install!!! AHH!

Any help?

Thanks all!

Did you try eebbaayy? EB search = Kawasaki B8 piston. or rings

The B8 isn't listed in the parts diagrams at Partzilla, but I did see a parts manual & workshop manual on EB.

Thanks for the tip. I have been checking ebay every day for 2 weeks. There is no piston or rings available for a 1.5mm overbore as of yet.

Total Seal

I called everyone

Wiseco said - That's not our part - The piston says Wiseco on it, the box ix Wiseco..I know its super old. The dude was a total jerk. Kept cutting me off.

Hastings
- The woman didn't even ask me the motorcycle specifics. Literally said we dont have rings for that. I never told her the bike!!

Total Seal
- We have rings for that on the shelf - Yes!!! Not cheap but available.

Hope this info helps someone.

The fact that Total Seal has rings on the shelf is amazing. Price is relative to rarity, so the fact they have them makes them a bargain. Wiseco is usually really good about custom making rings for one off things. Might be worth another try. BTW, don't waste your time and money on "OEM" NOS crapola from Asia. I've spent 12 years behind a Kawasaki parts counter and run into all kinds of horror shows from that s**t.

If you have a machinist buddy you might be able to convince him to machine a new ring for you. All you need is a lathe and piece of good quality cast iron.
See link below. If you don't have a buddy and you just go to a machine shop, chances are the cost of doing so will make the Total Seal rings look cheap. Good luck regardless.
