400ex tires fit yfz?

[400exfan19]

will my sand tires meant for 400ex fit a yfz? and one more question, after having a exhaust added and no lid, do i have to rejet after having the cam mod done?

[YFZ450Ridr]

the tires will fit just fine, the stock rim sizes are the same. the rims however will not fit, yamaha has a different lug pattern. i think most people dont rejet for the cam mod, mabye a few turns of the fuel/air screw but nothing with taking the bowl off. yfzcentral has lots of good info on this though if you search cam mod.

My stock tires and rims from my 05 400ex fit perfect on my 07 yfz. I don't know what he's talking about, but maybe it's just the 05 ex's to the 07 yfz...........

The tires will fit... But the bolt pattern in the wheels is different. The wheels will not fit. 05 EX rims will not bolt on a YFZ. Heck I wish they would it would have saved me a lot of $$$.

You don't have to rejet for the cam mod, but if you added a pipe and pulled off the air box lid without rejetting then you should because of that.
