Your idling speed is my average:) I understood that an engine should not be idled high enough to propell the bike?

I've not heard that before... might be something to it, might not. I mentioned it because when Harley and I are out for a ride, I usually idle along with her while she has some throttle open (not a lot, she's not a speed freak like I am ;) ). I'm not sure what the top speed on her bike is, it's only just past break-in and she's not one to wind it out the way I do. I think her TS is around 40-45 kph, using the same 66cc but with a 48T sprocket on the wheel (and a bit more over-all load on the motor). If I ride her bike (apart from my knees hitting my elbows when I pedal) it'll pop the front end up if I drop the clutch at high RPMs due to that torque sprocket.
I've always run high idle speeds, years ago when I was a delivery guy my beaters used to be dialed in to idle at around 45 kph, just a little below traffic speed.

(By the way folks, a quick guideline is that 10 kph / km is a little over 6 mph / miles [6.21 if you want to get finicky about it].)

My bike is a tank (60 lbs) for being an aluminum frame, the shift kit is a good part of the weight, Im gonna change that with aluminum sprockets.

me 185 lbs
country black top simi smooth
5 min = 2.1 miles 2.1 x 12 = 25.2 MPH
still lots of throttle left I ran it full speed and it burnt out the CDI have replaced CdI and will stay at a comfortable ride at the above average
 
Update: Now running 36 tooth and loving it! Perfect powerband with my pipe setup and much calmer cruising. Very nice for flat areas even with a big guy like me!

On a calm day the Auffenauger will cruise at 30 and top out at 35 with a Honda 49cc 4-stroke engine and a 40-tooth rear sprocket. With that gearing it doesn't handle hard headwinds well.

Peerless Leader also has a 49cc Honda 4-stroke and is geared lower with a 48-tooth rear sprocket and will cruise at 20-25 easily in almost any type of wind.
 
Mr.B, those bikes are really something. I can't tell you how much I like that '09 Ecaliber.

Btw, the average top speed of the earliest HDs, Excelsiors, etc, etc, were pretty much all within the 30-40mph range. You gotta like the fact that many of the reported top speeds on this thread reflect very favorably with that of these early motorcycles.
 
I don't know mine goes faster than I can peddle for any length of time . I haven't found a speedometer that works on my motorized bicycle yet . I have mostly decided it gets me from point A to point B and back so I am happy .
