I hear all this stuff about pulleys, chains, sprockets etc. and I know what they are and thats about it. What do they do and how to use them is what I don't know. I want to build a mini chopper but I don't really know what to do.

I NEED HELP :confused:

pulleys or sprockets set the ratio... chain or belts transfer the energy. ratio (to keep it simple) means how many revolutions it takes for the drive gear to rotate the driven gear once. So, in a 5:1 ratio, it takes the drive gear 5 revolutions to turn the driven gear/sprocket 1 time. For small engine setups, the drive gear is typically a part of the clutch and is driven by the crank. The driven gear is the sprocket and is attached to the axle or hub. The best way to think about it in our setups is that the closer you get to 1:1 ratio the more load you put on the engine the more top speed(assuming that the power is there) and the worst wear on your clutch, but the farther you get from 1:1 obviously the less load, but at a sacrifice of top speed and the benefit of less clutch wear. To get your ratio divide the driven(sprocket) by the drive(clutch) such as 60 tooth sprocket divided by a 12 tooth clutch = 5:1. I hope this helps a little... Oh yeh, with a pulley, its the circumference of the driven divided by the circumference of the drive pulley

Only because it won't go any lower :lolgoku:

... & since we're talking about post counts, you can't talk; you've been here 5.5 years, I've been here for 2 years & my post count is 5.5 times the amount of yours :toetap05: :lolgoku:

But what gets me.....uh hum.... my pet peeve. ...all that time and still no profile?

In my case, it comes down to nothing better to do. I'm sure, if I had a full time job, my post count would be about half what it is...

Might? That infers a possibility, it's not a possibility, it's a definite...

Technically, I'm not unemployed, I'm a full time carer & by full time I mean 24/7 so, not much chance of that happening in the near future...

This is about the basic and simple we can do for you. There is a bit of using ones own imagination with all of this.... hence this is DIYgokarts.com
http://www.diygokarts.com/chopper-plans/mini-chopper.html


Have a good look at a bunch of our bikes and you can come up with something, thats what I did when I joined. many years ago, and I even won a trophy at a bike show.

Edit- Pardon me, Fabroman has posted this link eariler.
