Reason I'm asking is because my welding class starts in about a week and I was thinking about making something like a folding version of a Riot (Seat, full suspension, etc...)
Now engine wise, the HF 2.5 HP is the most bang for the buck, but I think I want something lighter, and all the goped and robin subaru engines in the 20-35 cc range are expensive as ****. Anything cheap like this? Also anything that will like a CVT/multispeed pocket bike transmission? Also which ones could handle nitrous? I'm thinking a smaller engine plus nitrous on demand would be good for still having some speed but keeping weight down. I know you have to increase the amount of fuel when you add nitrous, so I was also thinking instead I could use a pre-mixed fuel/oil/nitromethane blend and just inject that (so the extra fuel comes with the extra juice right off the bat). Anyone know what would be best for cooling? I'm thinking either ethanol or methanol for the supplementary fuel.
Also, what would be my best options suspension wise? But OEM goped suspension, fab it, something else? I think I got and idea for the rear suspension (Get a coil-over of some sort and use a quick-disconnect like they have on those exercise machines, and then once it's swinging freely use that as part of the folding) But the front suspension annoys me.
Also, frame wise, I know I'm gonna use steal tubing, but any advice what thickness and such? Also I'm thinking maby using thinner steal, but getting carbon fiber tape and wrapping the frame and epoxying it. Is this a decent idea or a recipe for death?
Also, people who have worked with CF tape, how do you like it? I'm thinking it would be a good material to fab parts from because the goal would be to keep weight down. I know I'm either using this or kevlar with the running boards
