How fast will it go?

[LabDude661]

My 70 cc cruise real comfortable at 25. If I go a whole lot faster, the vibration kills me. I've hit 30 on the flat though.

My Monteray(32T) will do 35, The Jaguar, (36T sprocket)I just finished is faster, (lighter)
I think the way the engines are ported, tuned and increased Compression, make the most different in speeds.

Whoa, that could of been the ultimate in entrapment ever done!

35mph with a #13 gear on the flat is the best I have managed.

However considering thats from a piped 32cc engine its fairly impressive.

The highest verifiable increase from a pipe I have seen is 40% more power than stock which means 1.6hp x 1.40 = 2.24hp. I dont think I am getting that much but there is a fair power hike..

Oddly enough the pipe doesnt seem to have made a massive difference to fuel consumption.

My unconventional homelite weedwacker friction drive runs 22.5 on the flat, 15-20 uphill, and 33.5 downhill sitting upright (handheld gps). I've now gone thru 2 bottom end cranks since changing the top to a 30cc. new numbers have been 27 flat, solid 20 uphill, and 35 downhill - fuel burn 168 mpg....
I can't believe I just found out about motorized biking! Oh yeah, I've only got $25 invested and that was for 4 parts weedeaters to go with the one I started with. Last count, Frankenstein had 8 donors.

My 5-1/2 hp Jiang Dong on the Monarch with the 3-speed in 3rd runs 3100 on governor (cruise control) and goes 41 uphill,42 on flat, and 43 downhill and off a cliff. I am using approx. 2/3 of the engine. The "Happy Time"? runs about 35 but strangles wide open due to a restrictive fuel tap at this time. The 3hp Clinton in the Monarch an honest 40, but has seizures due to Clinton uses a round piston rather than cam ground and my rebore is a bit tight. The 20" Schwinn/Briggs & Stratton model N about 30. While I have the floor, AIG will write minimum liability for $43 for a whole year (in Oklahoma)

On my Trek mountain bike with Staton chain drive, Mitsubishi TLE43, I average 27-28 mph on my 20 mile trip to work, cruise at 31-35 mph generally (on flat ground) and have seen a maximum top speed of 40.35 mph.

yes - ones are very interested in MBs and do ask those same questions

wow - that is a mighty top speed you got going there

and certified by the pooolice man ------- pretty cool
