  1. I'l tell you what. I think those toomeys like a leaner main than that. 270 or 280 should do it at that elevation and temp.

     

    Also, sometimes when people think they have a lot of oil it's actually condisation mixing with the dirty stuff in the silencers dripping out.

     

    Since yours doesn't run right though I'm sure you have a problem.

  2. I ride slow wheelies but my engine is modified. Like I said, try jetting to see what you get.

     

     

    Why does almost every post turn to a bunch of little kids whinning on bhq anymore. Has everyone noticed a lot of the knowledgable old guys don't come to this sight like they use to. This sights turning into a bunch of whinning little kids. If I wasn't so bored at work I wouldn't even bother anymore.

  3. You just need to give it more gas or your pilot/needle jetting may be to rich to begin with. Try leaning your pilot by turning the screws out 1/2 turn or so. Also you can try dropping the needle / raising the clip one notch and see if that helps. Could just be a jetting issue.

     

    It is a 2 stroke and does react different than a 4 stroke for sure but you should be able to get decent slow wheelies with it.

  4. I bought a sun brand from advanced auto parts for 30. Read the same as Boonmans $150 ... but, when it gets old they don't seem to work very good. The little valve stem things start leaking and sticking. Boonmans will be accurate for a very long time.

  5. If you haven't broke in the rings yet the compression will leak past the rings. Run the engine a few heat cycles to make sure the rings are seated ( filed on the hone to the same shape as the cylinder).

     

    To test compression the engine should be cold, engine off, throttle open and kick until the gauge doesn't increase any more.

     

    If the compression seems low with a good gauge, put a tablespoon of 2 stroke oil in the cylinder. Re-do the compression test. If the numbers improve a lot your rings are not sealing properly.

  6. Did you take care of your flywheel when it was off. You don't want to bump or drop a flywheel or it will mess with the magnets resulting in less power at low rpms.

     

    Is the pickup really close to the flywheel. I don't know the spec but I make mine as close as I can get it. Maybe you have a week coil to go along with it. If it ran fine before,the weather hasn't dramatically changed and you haven't messed with anything else, it could still be electrical.

     

    Okay, just realized you did a top end too.

     

    Are the carbs synced, carb slides in correctly.. cutaway in slide facing airbox, choke tube in place between the carbs, float bowl with brass choke tube in it on the left carb.

     

    disconnect the tors too, the little black box under the left side of the fuel tank.

     

    Make sure the throttle cable is not binding or pulled where it splits under the tank.

     

    Jetting could be a little different since you, in theory, should be pulling in more fuel and air with the rebuild.
