I have a Briggs 3.5 on my Ruttman Toad and wanted to extend the exhaust a little bit. I'm pretty sure I can use just standard 1/2" pipe, since the port is threaded and I currently have a briggs thread on muffler on it. My question is, by extending it, at any length, will it negatively affect...

Ok...so on my cyclops mini bike redo, I was able to utilize a 5" internal drum brake. I'm leaning towards the 6" white steel rims for the FOX project and what little research I've done shows that I'll need a hub system and sprocket. What are my brake options? How do the parts fit...

Planning on running a Dellorto on a five horse Tecumseh on my Sprint. Really dig the look of the Rupp straight pipe with the turn-out. What's best for power on these motors? I've always thought some back pressure is better than none, except maybe at the strip. Discounting aesthetics, what...

Ok since I cannot find a rupp primary driver to save my life for my 71 roadster is there a comet or something I can use in its place? I saw a video on youtube of a guy who said he installed a new modified comet primary on his roadster. Anyone farmiliar with this or know where I could get one?

Hi everyone. I'm building a mx mini pit bike from a rupp frame to play around with and will be either using the animal or the world formula engine and am curious which torque converter would be best for my application. I understand that the comet 30,340, & TAV2 are only rated at 8 hp and...
