what fuel should i run?

[blasterguy15]

alright so my dad got this 2006 yfz 450 and it blew up in 2 rides well the crank seized up and now we rebuilt it and it got rebuilt with a 3 mil crank and a 13:5:1 compression je piston should we be running race fuel? or can we mix 91 and race fuel?:-/

13.5 is pretty high, be safe run race, jmho.

Don't know about an 06, but look into "oiling mod" for yfz
