love the pipe......more info!!!! did you buy it or build it?

I always like experimenting with bikes. I don't have a regular homemade motor bike like this, but I do have an electric bike. I am also working on this gear idea called The Gearcycle. Ever tried a recumbent bike?

Hey man, great build! What expansion chamber are you using? Is it the SBP one?

the steering dampner of a motorbike is a nice touch, heck my motorbike does not have one lol

Totally Sick machines!!!! Awesome job! It would be awesome if you could tag the pics with the special info for each shot, such as engine, carb, and such. Its easier than writing a full instructable. And, is that a Nitrous system?

Very nice with the tank and paint and everything. Those are my favorites, but what is the tank made out of? How did you do it? Also what is that piece connected to the frame and extends out to the handlebars?

Plan B (author)madwheels372012-04-02

The tank was welded from 2 inch Al tubing
This is a Steering damper
These are used to absorb vibration mostly on motorcycles
Thank you

Steering dampener!

Its a modified 66 cc 2 stroke with 24 mm mikuni , Over 12 to 1 compression,
bike goes over 65 mph ( checked with GPS )

pyrogreasemonkey (author)Plan B2012-01-03

you must have really modded that thing like crazy to get 12-1. i have one and the ports are not good at all stock. what kind od dremmel bit do i need to smooth out the intake ports? they are at a weird angle

Koolaide58 (author)Plan B2011-07-18

what kind of tires do you have to take that speed ?????

snowluck2345 (author)Koolaide582011-07-31

I'm wondering that too.

mo5 (author)2011-04-27

is that a pocket bike motor? and how did you mount that?

Plan B (author)mo52011-04-27

Hi there
The engine was bought as a kit on e bay . The engine had a universal mount but they do not fit most bikes very well. For every bike i build i also fabricate a new engine mount on my milling machine for best fit.
The engine has been modified by me for speed :)

is it me or does that black bottle look like a nos bottle

nice bike how much did it cost ya

Plan B (author)hightekrednek23962011-03-10

The black bottle is nos.
The whole bike was about $ 500 in material
and about 40 hours to build

BIGHAIRYDUDE (author)Plan B2011-04-20

what made $500? im thinking about $350 in motor and parts without bike

scraptopower (author)2011-03-16

Way cool! I want this for a zombie dodging survival vehicle! Hope you win! Will it run on decomposing corpses ? :p

Plan B (author)scraptopower2011-03-16

Good Idea
I could add a pressure vessel for the corpses and turn them into swamp gas.
Then mix it with some NOS and force it into the engine.
For Battle speed . ;)
Thank you for your comment

Very nice build. Normally I don't like motorized bikes, but this is really cool. Good job!

Plan B (author)axlejor2011-03-11

Thank you axlejor
I wanted to keep the clean lines of a road bike on this build.
With much more speed :)
