And there is the problem of Wisconsin law restricting our MB's to 49cc's.

Tom, are you sure about the 49cc requirement? I thought Wisconsin statures are pretty liberal about this stuff. Take a look at the stature below defining a motor bicycle. Technically, if your friend's 212cc predator can really go no more than 30 mph but can get him to 30 mph in 1 seconds then it still could be a motor bicycle in Wisconsin. :D

340.30.a
A bicycle to which a power unit not an integral part of the vehicle has been added to permit the vehicle to travel at a speed of not more than 30 miles per hour with a 150-pound rider on a dry, level, hard surface with no wind and having a seat for the operator.
 
You know what the nickname for a helmetless rider is? Organ Donor.

Tom, my HT motor did about 32mph on its first trips out. Worked up to 36-38 as it broke in.
I agree with KC Vale's comments about blinking strobe during daytime riding. Needed.

Agreed as well on a better tensioner needed.
I was meticulous with no problems so far, but am planning a slotted bar between both rear tubes, and a 2" roller with real bearings.

steve, i slotted a bar too on my 2 stroke because the tube was too narrow to get a strong grip for the tensioner. my new bike bar has a much wider bar so i was able to get good torque on the bolts and locked it in with double nutting with friction nuts. the metal bars are like 2 usd at hardware stores, but mind the material.

Steve,
I have crashed on my R80/7 BMW road rash and some subdural hematoma I wished I had pictures of to show the grandkids. I own helmets and use them but my observation has been that when wearing a helmet I tended to take
more risk. There were some great rider defense articles in Rider magazine back in the 70's written by Stuart Monroe
that are a part of my every day riding/driving habits. With my buddy operating his Huffy Dear Row 212cc commuter
in town I told him to get a helmet.

bakaneko, The statutes in my ring binder and down loaded from Wis. DMV specify 49cc max. but you got to remember that these statutes are written by law makers in a lot of cases where all they have is other states case law to go by.
My buddy with the 212cc NOWS his is illegal cc wise (I keep telling him) and takes it in consideration. There is a clause in state law that allows cities to register and tax even 49cc bikes if they become a local nuisance. Some thing I don't want.

aye, aye. local municipalities can set their own statures regarding motorized bicycles that supercede the states. i keep it on the down low too. nothing too fast or crazy. i think 49cc is enough for a motorized bicycle. you gotta really know the engine and work for the extra speed and torque.
 
I've heard that the 49 can actually out run the 80 if done right due to the motor actually being balanced and since the oiston is smaller more RPMs

Hi Frankfort. Just as a pubic service I need to point out that there are no 49cc or 80cc 2-stroke engines.
They are 48cc and 66cc when measured.

Sure, with gears, a 48cc will kick a 66cc, and even an actual 53cc 4-stroke with gears will kick most any 2-stroke 66cc direct drive even with mods despite the extra weight.

My point is simply learn actual REAL engine sizes before you start talking about them is all bud, and if you want to talk to about speed think gears, you can haul butt with little power with gears ;-}
