He guys, I've rejeted my 250 a dozen times and it's a piece of cake. But I got a new yfz and it's time to rejet it. Do the same rules appy? I would think it would be harder because you don't have the major change in plug color with a 4-stroke. I've been riding for 15 years, i'm just new to this 4-stroke deal. lol
Thanks for your help!
