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?
 
From what we discovered this weekend(crf450)
U will have MORE than enough power...work on handling
If you can Put the power to the ground and you'll b upfront
 
Thanks for the info
Im sure I will have more questions along the way
I pick the motor up Saturday can't wait
 
Ok u will need a oil tank then and or the block off kit from DND that is a rip off but a nice kit i have had to buy 2 of them kit makes me sick
 
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.
 
Thanks for the link
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
