I'm thinking of putting a 33cc chainsaw engine on a bike with a torque clutch and a number 14 tractor chain. This will be my first time doing something like this.Does anyone have any tips or tricks ? Feel free to brag about stuff you have built.
Get a bigger engine... 55cc 62cc add a second sprocket that runs free in reverse , then u can peddle to take off and let the engine work under less load. You can have a look at some motorised bike kits online
As long as it's done right the added wear from friction drive will hardly be noticeable.
I prefer the simplicity of friction drive over chains, spockets and jackshafts.
With friction drive you can have it going over a weekend. No messing around with machining adapters to hold a sprocket to the rim and aligning jack shafts.
>I don't wanna pedel though
He's not suggesting you pedal the whole time, he's just suggesting that you don't use a chainsaw engine to tug your fat ass around and actually get yourself moving before you start breaking the fucking motor
Get something like this
I bought a similar kit, welded up an expansion chamber to replace the shitty muffler, added a chain tensioner and built a larger fuel tank. It will do about 35 mph and gets 60-80mpg. I've had to do two top ends in about 4000 miles, the bottom end will probably need replacing soon since there is a pretty strong rattle at idle and some play in the crank.
