Well I just got done remounting my zoom "80"cc motor on a new frame.
The old Jamus kept braking at the seat tube. So I got a "new" frame at City Bikes in Portland OR.
It was a older Giant 20 inch and I asked for something with an 1 !/8th head tube.
The frame I picked up had a 1 1/8th head tube but it was not set up for suspension fork so it was
unstable (BB too high) so I dug around and found a 1 1/8 threaded fork Then I brazed on new V-brake
bosses for it. I also found a stem that fit (140mm) along with some old bars that are alot older than
quite a lot of people I know.
Since the headset I had in the shop was bad I got another and then I installed it and the brakes + shifter
I only need one chainring because with a 34 in front and a 11-32 in back I have lots of range and with my
SBP pipe it really can get out of its own way. Its been about a month since I have a motor between my legs
and I forgot how fast that thing can go.
Its got a SBP tuned pipe and a thinner head gasket plus a 36 tooth rear cog that I have bolted to a DEORE disk brake hub. last time I had a computer on it It came very close to forty on the flats with my old frame. I am hoping with the better rider position I may get a few more mph out of it.
I have been riding my pedal touring bike (read heavy, poderuous but stable) and my road bike (lighter,quicker but
winpy motor) Now I can't wait to get my motor bike on the road. All I have to do is set it up with fenders,
rack and some lights and I will be set for the rest of the fall and some of the winter.
I will post some more pics as I get it done
