    After three weeks of waiting on parts I finally got my TT350 back together and am working on getting it ready for the season. It's backfiring through the carbs and out the exhaust and I'm pretty sure tight valves are part of the problem.

    Intake was 0.003
    Exhaust was 0.005

    I don't know what the specs are, but something tells me all the valves are at least a couple thousands too tight.

    I have this tool for my other Yamahas, but it's no good on the TT.

    Anyone in the Boston area have the correct one they'd be willing to loan me? Or is there a workaround? I might just pull the cams to do it if I have to. I really don't want to wait another week for more parts - it's finally warm out and I want to ride!

    I think this is all I need.

    I must be able to find something I can wedge in there instead. hmmmm..

    I posted about this a while back (XT350). You can evidently use a screwdriver just fine (with only modest care).

    Cept you don't even need to. According to CLymer, spec is 0.003-0.005 intake and 0.005-0.007 exhaust.

    I think you got a different Backfire Demon.

    Interesting. Thank you for the reply nails. I was thinking a big screwdriver might be the ticket - but I guess I don't need it afterall.

    I know I'm still flooding a bit, so that and my carbs being unbalanced must be the sources of my backfiring.

    Thanks!

    I'd take out the cams before using a screwdriver, one slip and you'll screw up all sorts of things. I used to take out the cams all the time before getting the tool, just takes a bit longer. I use metric dimensions, intake .08-.12mm ex .13-.17mm
