What engine do I have?

[James1968]

First I made the horrible mistake of buying a engine kit from bike berry. The reason that's a bad idea, well they don't know what they have sold you. I want an extra cylinder and piston, heck that should be easy! NO I call them, tell them i have the BBR stage 4 kit. And want an extra cylinder and piston. What they tell me is you will need to figure out what you have. So here I am looking for help! My jug is 40mm intake and exhaust, Type A piston, the rod says zl40mm. Can anyone tell me what jug to buy? a link would be great, the best quality I can get. I would like an extra jug,piston,and upper bearing. ported jug would be better, that way I would't have to do it lol. Thanks for any help that you can give.

sounds like the cdh 40mm stroke motor - does it have two fiber base gaskets?

if so, I get cylinders from mzmiami on ebay

I have been told it’s a b piston. It did come with two base gaskets. I took one out.

I don't care about A or B, I just looked at your pic and saw high wrist pin.

you NEED two gaskets there - they both, prevent piston hitting head, and ports being too low for best performance
