37 mph by the radar chrono
My Kings 70cc/ 44T, on max-inflated 26-inch street tires, with me hunkered down low and throttle wide open, clocks in at 37 mph at my nearby "Your speed" radar warning display before a sharp turn.
Coming from the other side of the turn is uphill at a pretty decent grade, with another radar warning, and I consistently clock 30mph UPHILL. I weigh 180, and my bike weighed 29 or 30 lbs before the motor.
Funny thing is, as long as I watch out for bumps, the bike/motor felt stable at the speed. At least till it busted the bike frame last night. The engine leaks quite a bit fuel from... somewhere... but runs strong.
I use 87 octane, which someone told me was less sensitive to humidity, and I put a little bit of isoHEET and Stabil in each tank.
Oh yeah... I took off the lower part of the muffler and drilled a hole in the bottom of the pipe to let the gases flow straight through. The sound bouncing of the pavement is probably 95dB and I have to wear earplugs, but I appreciate the fact that drivers can hear me comin. From WAY back. Sounds like a 2-stroke Harley.
