    Hello everyone thanks for the add to this Forum. I have recently purchased a PK 80 stock NT,the only mod is a banana expansion chamber. NGK B6HS plug. Run 3 tanks at 16:1 now at 32:1. She runs very rich (4stroking?) at idle to 1/2 throttle, i have moved needle clip to top notch (helped some) running without filter helps a little also, set float to 22mm. Also in the cold morning runs much better. What about jetting? Thank you for your time PEACE!!!!!:-||

    I'd put 150 or so miles on it before I tried any real tuning - they always go leaner as they run in.

    I concur with Crassius... Wait until it's fully broken in before trying to jet it.
    (it might not even need it when it's fully broken in). ;)
