i recomend building one from scratch or at least from a frame that is ment to cary a engine mounting a big enough one on a bike would be very tricky

if you can weld make one if you cant find someone who can and design it all out with some where to put a good size lawn mower engine

something like this

with that design, when i run out of gas im screwed. thats why i chose a bike

The chain from the saw has teeth on it

If that caught your leg you would not be very happy.

The pluses off this project for me:

if it works i may be able to ride it.

i will learn soemthing new.

The minuses:

I'd be to afraid of chain sawing my head of to ride.

his parents wouldin't let him do this.

:withstupid:

chain gaurd IS a major duh isn't it? :violent2:

I'd go with the lawn mower.

how do you adjust speed on a mower engin btw?

well you take the gov linkage off and then attach a cable to the throttle butterfly in the carb

Well first off I had the same idea but I never completed it because of lack of money and materials. But there is no reason why it wouldn't work. A chainsaw has plenty of torque to spin a bike tire and theres not really that much that you could mess up on that would put you in danger. You would probably need a welder to atleast weld a bracket for the chainsaw. But I would defenitly try and use the chain that the bike came with. All you really have to do is attach it add a centrifigul clutch and just put a throttle cable on. You could just use the front brake handle as the throttle handle since you wouldn't be using the front brake anyways. And I would not use a lawnmower engine because they are heavy and almost all of them are horizontal shaft engines.

how would i mod the harnd brake to be throttle?

pyromaniac · Tue Apr 10, 2007 7:12 pm

My dad could weld that for you.

I saw this thing on instructables about some people who used a pneumatic hand drill and an old propane tank filled with compressed air and they geared it up to a bike and it worked. I reckon if you had a better drill (maybe even a steam engine) and a larger tank (say a dive tank) you could make it have quite reasonable range. you can look it up on instructables for the full details.

I just thought that might interest some people because its kind of related.
