Big bore

PostAuthor: Lawbreakingtrucker » Fri Aug 25, 2017 2:25 pm

I've read threads 6 and 7 years old threads about big bore for the 250 engines..
Do any of You guys still ride these bikes and did the engine modifications work for a longer period of time?
I've just got my first bike this year and I love to work on it in my garage. This winter I will give it some more power and I'm looking into making it a 280cc engine. If any of You guys that tried this in the past will point me in the right direction I would appreciate it a lot.

My plans for the bike is inspired by Larish41, bigger homemade exhaust (1-3/4"), 52mm pistons (280cc), maybe bigger carburetor and changing the sprockets to 17/40.

Any thoughts on this for my clonebike? Jinlun Spartan JL250V
