    Yamaha Royal Purple/Amsoil

    Ive heard good things about Royal Purple and Amsoil motor oil, my break in period is almost over and I am wondering what the best oil to run is and how often I should change it? Thanks

    YZ exhuast cam in YFZ

    Its going to the dealer in the morning so we'll see what happends..I agree that it may be the timing because If im running both YZ exhaust and intake cams why wouldnt the timing be the same as the YZ I think the dealership left the YFZ timing instead....another thing is did the dealer screw me by telling me to buy the YZ exhaust cam instead of keeping the WR when all that had to be done was retard the cam timing by one tooth?

    Yamaha YZ exhuast cam in YFZ

    I recently bought an 05' YFZ I had the dealership throw on an HMF slip on K&N Pro Flow kit and jet kit and a YZ exhaust cam. The engine acts like it wants to start but it wont without giving it a tiny bit of gas. The problem is it backfires and shoots a flame if I give it to much gas. Possible timing issue or jetting issue?...Anybody have any ideas?
