my home made clutch v. chainsaw

[Magice]

I have a 100cc husky 200cd that was just rebuilt, and I wanted to put it on a gokart. I couldn't find any pre modified clutches so I modified it myself

Works wonderful! :wai:

The pic is unfinished.. the final one is cleaned up more, and the spacer is ground down.

It seems to hold up good on a chain without breaking.. not on an actually kart yet.

Will the larger tooth configuration cripple my speed?

It's two bike sprockets riveted together. I then took a cutting of big metal tube, stuck it on clutch, sat sprocket ontop of it and brazed it.

I would have welded it, brazing never seems to hold up in a application like this. IDK, you can try it. A chainsaw go cart is badass, those engines are so torquey.

[Magice]

I couldn't get the welder in there - brazing it was hard enough.
I'm actually looking for a 200cd clutch to rework the idea of adding a sprocket to it. I had an extra laying around but I can't find it anywhere!

I'll keep you guys updated of how it works when I mount it on my track kart :)

2 bicycle sprockets?! So tell me... what chain does that use?

[newrider3]

Bicycles use #41 chain, which is just a narrow version of #40 or #420.

[Magice]

a #40 works fine.

The brazing will break :(

[Magice]

I'm thinking of sticking little chunks of metal in there and welding it to re-enforce it. I have quite a bit of clearance to work with before it hits my chain.

[athif]

Im guessing that metal is Cold rolled. If im correct, brazing does not work well with cold rolled metal.

You should of welded it shut.

[I like karts]

Wow... that kart will rip. Chainsaw engines are awesome

[Ibnzmonkey]

wheres all the pics?

[aelo]

nice can you post me more pic.

chainsaw engine don't have that much torque they have to rev like 8000rpm before they make a power

have you ever cut down a tree with a chainsaw bigger than 50cc? those things got some power to them, especially if there a good brand (husky). My 1970s mcculloch which is like 54cc has so much power too it, it will shake your arm right off.

[motor_head]

they cut easy because at 8000rpm it only takes a little bit off at a time
as to shaking your arm if you mean vibrations then its poorly ballanced

[Kaptain Krunch]

Ok fine, bad example, have you ever actually used a chainsaw engine bigger than 50cc in a minibike ? They have plenty of power and torque, they used to use 100cc Mcculloch engines in racing karts back in the day.

[motor_head]

i guess 100cc would be good but you have to gear them down so much 12:1 idk something like that but you end up running 6000rpm just crusin at least with smaller one like i said 100cc might be good though
