Other standup bikes I've been building (50MPH goped video inside)

[nidyanazo]

So... Decided to build some killer standup bikes.
Using the venerable GSR frame, and on this first one I've got a ultra rear $2,000 Trevor Simpson 62cc modded motor, ported by chris bartolone

Ful porting throughout motor
Eton fan cover and upgraded RC coil/ rpm limiter removed.
MSD plug wire w/ champion plug
Custom Bartolone racing pipe with heat wrap and a carbon fiber silencer,
K&N Filter, delrin intake spacer (heat shield) and one **** of a CARBERETTOR, with a 1/2" velocity stack..!!

15:1 compression dome, runs VP red 110º race gas with Maxima Castor 927 @ 25:1 ratio..

Here's the Italian Polini engine, this is a brand new 5 port, with a black race crank (impossible to get) and a bunch of crazy mods. Same exact setup that won the world championship.

Also putting it in a GSR frame. This'll do 55+mph and wheelie off the line. Should be a bit faster then my 13+hp Morini 50cc street sprinter bike.

These things are seriously fun.

Here's my 6+HP 30cc hard tire fully built esp ported sport

nice. where did you get that clear cover on the polini?

Wow , and I thought my Morini was overpriced. Those are nice toys and (thanks for sharing) all Id just rather sit down and cruise Im pretty put off by the on/off nature of 2 stroke race engines anymore. These low RPM higher displacement motors (HS, Honda GX, Harbor Freight 99cc) just seem to lend themselves so much better to the typical 70 plus mile cruises we do here in San Diego. I dont think I could do 70 miles standing

Fast, yes! How about the brakes? Driving between cars!?

Every riding video you post seems to have the exact same theme... full throttle racing on residential streets, dodging in & out of traffic & generaly just breaking every law there is.
