Engines for pit bike (140cc+)

[Legal_Brap]

Hey guys. Chain broke on my bike, then it broke the entire engine casing. It currently has a lifan 125cc, I was looking to installing a big bore kit. I thought well this is a good chance to just buy an engine, since repairing the damage plus the big bore kit would probably cost around the same. I want a 140cc and up to 180cc. Any ideas on what engines I could go with?

Most pit bike engine's will fit.
You might need a longer clutch cable for the one's with a rear mounted clutch.
GPX125, Lifan 140, Lifan 150, YX150, YX160, Z160Ho, Daytona anima 190FDX should all fit
And what's your budget?


What sort of bike is it? any pic's ?
The only thing is the bigger cc engine's are longer, so you need clearance to your front wheel with full suspension travel.
