From first hand experience this can hurt you. IMHO, Yamaha has not done enough to publish/remedy this. SrIuSlY 01-31-2010, 10:41 AM i run a yz 250 '02. ive been running a mixture of 40:1 for 8 years this is the best mixture that will not foul your plugs. nothin wrong with running rich but youll be changin plugs like crazy. but that is a great bike ive never had a problem with mine. crazzzy fast. run a 52 tooth rear sprok for more bottom power. | |
