I have an 05 YFZ and i have some mods done too it i have read that you can buy the YZ450F dirtbike crank and put it in the YFZ and it will bump you cc's up too 449 or 450 cant remember which... But the crank is $350 and i was wondering if it is worth the money?

Thnks Jamie

 

y do u think that will help u any? i mean i won't against my super raptor LOL. No i wouldnt seriously you'll lose reliability and only gain a couple of hp. I still wan't to be a formidible opponet not just a warm up.
