Vader Big Bore

bman393 · 10-15-2018, 02:03 PM

Ive been thinking about engine swapping my vader 125 with a cr250 engine, but then I would run into problems on finding parts every time something breaks. Now im thinking about putting a big bore kit in, but not sure if it fits the vader. Anyone know if it'll work???

As far as I know all the horizontal engines, from 50cc to 125cc, like the GY6, use the same block. Doesn't matter if it's Japanese or Chinese. The same big bore kit that fits the 50cc CRF also fits the KLX110.

Bore kit will work. you just need to get one that's the correct pin size. There are slight variations.

How much are you looking to spend? For about the same price as a bore kit, you could swap a 150cc Piranha. For a bit more, you can do the 190cc.
