Big Bore Kit for X-Pro 125cc engine

antagony · 05-04-2025, 07:50 PM

Hello,

I have this engine: https://www.powersportsmax.com/produ...ducts_id/23832
Here is a link for the cylinder head measurements:

I'd like to upgrade it with a big bore kit. Does anyone happen to know any compatible kits for this engine? I need to replace the cylinder head already. Would a head and body from a 140cc work as an upgrade?

thanks!
Nick
