Hello all. On my second tank of gas. Bike ran well and had lots of power. Easily got to 20+ mph. Now i can barley get up to 10 maybe 12 mph. I checked carby for leaks and put plumbers tape ect around it to secure for leaks. Now i spray starter fluid to check for air leaks .while running and the motor stalled out? Did this several times with the same result. I am at a loss. Any ideas? Still has no power!!?
