I have come across a Yamaha yz426 engine for cheap
Jumped timing
It can be repaired pretty cheap
How would this motor be on a kart and are there performance parts
Like cams maybe bore it to make a 450
Any thoughts

Bad to the bone, on a kart. You may want to leave it stock and sort out all the chassis tire stuff that'll go with it. then when you think you've gotten all you can. you can start looking for more hp.

Yup. Make a 430# kart handle. Then look for power.or more power.

Tim, did you ever get crf bottom made?
 
the yzf426 is nothing more than a destroked yzf450.

Tim u had a remote oil tank on a honda 450? I thought they were all wet sumps but i dont know

I have a 08 rmz 450 and I chopped off the tranny and made a remote oil pump and reservoir. I'm making molds to cast conversion cases now so people will be able to convert a 450 to a kart and all my kits will have a remote pump and reservoir.

I'm going to try to do a lot of it myself
If not I know some pretty smart people with better fab skills than me
