Need a little help from anybody who has done a four stroke shifter, I have a Kx250f four stroker that I have on chassis, (unfinished project from another owner), and it has the stock drive gear which is meant for a 520 chain and I am needing a drive gear that is for the more commonly used 428 chain. Anybody know if the KX 2-stroke gears will work? or can something cross over from another manufacturer? Anybody known where I can purchase? Thanks!
It’s probably not made so you’ll have to make it. Take your gear and get a machine shop to cut it down then make a spindle and weld a 428 sprocket to it. I had to do that when I put together a CRF 450 Kart.
