I don't know what to call it, but it goes and stops now.
It's a project I didn't need, but bought as a roller a few months back because I couldn't pass up the funky thing.

It handles like...well, a shopping cart dropped from 10,000 feet, but I took it down the gravel road today and didn't die.
This is a one-of-a-kind home brew. That's code for booger welds galore (a few of them are mine). Understanding the original builder/s probably threw this together with things they had lying around, as a fun project, it's important to keep that in perspective to the changes I made.
New custom 1" rear axle (right wheel 3/4")
New tires all around
New left wheel
Used replacement right wheel
New axle bearings
New axle lock collars
New hydraulic disk brake assembly
New chain
New rear sprocket
New air filter
New carb gaskets
New spring seat
I converted the current engine from points to electronic ignition using parts from two other 5hp Briggs engines I have.
It was a bit more than I anticipated to get it where it is now. Mainly the rear axle and related parts. What they had on it was some type of riding mower differential that was a total mess and had axle stubs welded to it that were all kinds of off center and not useable. Literally couldn't replace the axle bearings without cutting the axles off. The gearing they had was for like 40mph, which is certainly reaper taunting speed on this thing. I got it set for around 25mph, and that's still not a walk in the park.
I tried it with a live axle, but with the steering geometry and such little weight over the front, the turning circle was in hectares, not feet. Now, the left is the drive and braking wheel, and the right is on bearings. Under brisk acceleration, it pulls hard to the right, but levels off with less throttle and goes relatively straight when cruising. From a stop, it makes a right turn in a really small circle. :p A left turn isn't too bad either.
I had to completely redesign the brake. They were using a cable operated rear master cylinder with a remote reservoir, and it was all frozen when I got it. The new brake is overpowered, but stops straight. No problem locking the tire up. The 'new' sprocket isn't true, so the brake pulses when lightly applied.
The rear axle was a compromise. The whole thing is just goofy and nothing is going to handle well anyway. The right of the axle is keyed, so it's easy to put a different right wheel on to make it a solid live axle and ride wheelies all day, it'll just turn poorly.
Obviously, the front forks have so much flex, rough roads have it bouncing like a caffeine infused, Mexican jumping bean.
I really don't have the room for this and need to focus on other projects, so I'm going to try and sell it. If I don't, I'll modify it to a theme to use in some nearby parades.
