Re: anyone jetted a oko 21mm with a bbk? Have some questions.

Yeah, they are quite a bit nicer of a engine, but waaay bigger. I compared my spare basket case engine to the roadfox, and its like twice as big, no way you would be able to swap them without extensive work.

If there was a easy af16 available locally I would consider it. A quick look has turned up nothing, and engines are plentiful on yja. I figured a af18 as they have double bearings in the trans I believe, and might as well get an 18 with everything. the ports not a big deal, you just seal it up and w...

I ...
