    Powervalves Removed?? Opinions...

    I tore down one of my skiis last night...xlt800...and first off i wanted to say how dissapointed I am in yamaha engineering I am on this one! I should have just yanked the freaking motor out, would of made it a ton easier...

    What i found was both powervalve heads missing! The faulty clips and the broken tops were still in there!! dumbasses. There was a slight knick on one of the pistons, and it appears that they installed new rings and ran it. What i dont understand is why they left the top of the powervalves intact and pulled the rest out? again, dumbasses. And secondly, if i were to replace the valves i would do it right and spend the big bucks...and i dont really have the money right now to do that. Anyone run that 800 without the valves? Ive had srx's and sxr's over the years, so i have an idea of the performance difference, but no experience with this 800 twin.

    yea the 800 is alot of fun pulling apart
    1200 is alot easier to get to the PV due to difference in exhaust
    you can buy replacement valves for $60
    yea they arent billet but are better than the first version OEMs
