This might be a stupid question, but please bear with me because I'm still relatively new to these buggies.
I understand that there are countless different versions of these GY6 motors, and that each of them has their own differences. I recently got a used Razor Vision Z-2150R. The engine on it looks just like this one which is advertised as a 150cc engine.
It burns oil bad, so I was going to rebuild the top end of it and get a kit, but to make sure I was getting the right thing, I went ahead and took apart the top according to a guide I found somewhere online (can't remember where) and I noticed the cylinder stated 124cc.
Also, on this piece, it says 125.
Could any of you help me identify my engine? Is it a 150cc or a 125cc?
Thanks everyone.
