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) says: Apr 2, 2012. 8:00 PM
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

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 says: Jul 18, 2011. 11:25 AM
what kind of tires do you have to take that speed ?????
snowluck2345 says: Jul 31, 2011. 5:07 PM
I'm wondering that too.
mo5 says: Apr 27, 2011. 11:33 AM
is that a pocket bike motor? and how did you mount that?
Plan B (author) says: Apr 27, 2011. 5:30 PM
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) says: Mar 10, 2011. 9:27 PM
The black bottle is nos.
The whole bike was about $ 500 in material
and about 40 hours to build
BIGHAIRYDUDE says: Apr 20, 2011. 7:16 PM
what made $500? im thinking about $350 in motor and parts without bike
scraptopower says: Mar 16, 2011. 3:07 PM
Way cool! I want this for a zombie dodging survival vehicle! Hope you win! Will it run on decomposing corpses ? :p
Plan B (author) says: Mar 16, 2011. 5:14 PM
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) says: Mar 11, 2011. 4:25 PM
Thank you axlejor
I wanted to keep the clean lines of a road bike on this build.
With much more speed :)
