Hey all, been a while since I've been on here. Winter time in the great Northwest and I had my Ruttman stored away. With good weather coming up, I've decided to "soup it up" a little. I already ordered parts, but I have a question. Will a gear ratio of 3.5 to 1 work? I ordered a 17 tooth...

not sure what a good gear ratio to shoot for is. I have a 6 horse with a 10 tooth clutch and 60 tooth sprocket and I will be adding a jackshaft but do I want to stay with 10 tooth spockets (final drive 6.00)on the jackshaft or like a 13 and 17 (4.59 final drive)...I'm not looking to set land...

Forgot I had this little engine sitting in the shop. Kind of cool with the gear reduction.

Have had this stored for many years. It is a 30 tooth #35 chain 1st gear. Has the bearing support, keyed for a 5/8 shaft. Mounts to shaft with a roll pin. Maybe fox or ??? 58.00 shipped. Postal money order only please. Regards, Joe51

I just want to hear some experiences with high gear ratio and the other factors that go into play along with them such as: Weight of mini-bike (or go kart) and operator combined. Gear ratio. Size of tires. estimated top speed estimated time to get to top speed. `My personal experienced...

Built a drift trike but having issues with standard centrifugal clutches burning up. Decided to go with a TC but current frame design prohibits normal mounting. Is it possible to mount the driven gear on the outside of the jackshaft? If so, will the bearing be able to withstand the chain load...

Hi, I have started making a frame for a minibike. The rear wheel is a 15" diameter (395mm), has a 70 tooth sprocket on it #428 pitch and size chain. The engine I have is a 3hp briggs. What gear ratio would I need for hill climbing and going slower for the kids? I can get a 12...

Hello everyone, questions from a newbie. I just recently acquired a 5hp Briggs I/C motor that I was hoping to use in a mini bike. It has a reduction gear so when I took it apart I found that it has a splined crankshaft for the gear, not the round shaft with keyway I am used to. I am a lot more...

Hi all, obviously brand new to the forum. My cousin and I have been working on restoring an old mini trail bike. To be 100% honest I'm not confident it's a Bonham brand, it very well could be a Sherpa or some other random manufacture. I've installed a new engine in it which is working fine. The...

Hello. I recently bought an old (1968) 2 hp flat head Briggs on a local swap meet. It seems to be in good shape except for the gas tank, which has seen better days. Now I'd like to build something fun with it and I thought of a minibike. I don't know if the 2hp is strong enough though, what...
