Are you sure? You can get 146cc BBK for the GPX and Jialing motors... Was it the whole thing or just the gudgeon pin diameter?

 

[gavgav]

the kit they sent me was for the jailing motor and the sleeve was too long

OK yeah... I'm not real sure on this one... i thought they had the exact same specs... must have been wrong. that's cool though someone else will give you a hand sooner or later lol

the sleeve was about 11mm too long

wow thats a massive difference... but you can get a 146 for the GPX... maybe just need to take a few measurements of you motor and look around... It might not be called a GPX 125 big bore kit or something like that... Ask dabomb he has a 146 kit on his jialing
