Went to dunes this weekend. Bike was doing fine. Pulled into camp, had lunch. Went back out and bike wouldn't run. Starts and idles normal, runs fine till 1/2 throttle. Over that it falls on it's face. Kinda fills like its crazy rich. Swapped over from another bike the coil, stator, flywheel, wiring harness.Tried new and old plugs. Swapped over the other bikes carbs. Pulled reeds and power valves and inspected them. Tried a buddies alky. Did a compression test. Swapped whole fuel tank and pingle...I'm baffled....Bikes a stock stroke 68mm PV cheetah. 38 alky lectrons. Tried going up and down on needle. And adjust pj, made no diff past 1/2 throttle. Redline port and domes. It's been fine and ran flawless many weekends till it sat literally an hour... Any help is appreciated!!!
