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!!!!!
