First of all a thanks to Rich for the ida and the advice. This scooter was given to a friend of mine and he wanted me to build him a custom. I'm kind of going for a cushman eagle look. The engine is getting an 88cc big bore kit, performance cam, 150cc carb, big valve head, 1500rpm torque spring, and 9.5 gram sliders. I'm going to weld in a tube from the steering collum to the seat mount and mount a fuel tank on it. The seat is an old style harley solo seat. I will post picks as I go along. Attachments:

The seat I'm going to use. I still have to order the springs as soon as I get the back mount welded in and figure out what size I need. Attachments:

Putting the engine together today with the new parts. Bore is going from 39mm (49cc) to 52mm (88cc). Earthman, I'm not doing a hard tail. I just like the look of the solo seat with springs and maybe it will be a little softer ride. Attachments:

Got the tube made. Still need to weld it on and paint it. Tank is just temporally sitting on it to see how it looks. Attachments:

First of all a thanks to Rich for the idea and the advice. [/size][/quote] Well, I'm honored....really. It looks like you already have something very special coming along, I will follow the metamorphosis of your project ardently. I envy your welding skills, that would have augmented my undertaking markedly. I keep passing this welder at Lowes everytime I go in there, I think it wants me to take it home.  Thanks for the great posts and the compliment. Rich |

Next time take one home. I just started welding a couple of years ago. I still have much to learn but I'm getting better all the time. The best advice I can give is to buy the best auto tinting welding helmet you can afford. It really speeds up the learning process being able to see what you are doing. I got a book at Home Depot that was a big help getting started too.

Today I moved the engine forward about 4" by eliminating the motor mount. It brought the cylinder more into the step through aria and the back tire dosnt stick so far past the frame. I think it tightened up the look of the scooter. Attachments:

Wow, looking great so far. Well you beat me to the punch on getting rid of that ridiculous Sino-motor mount. I was going to do that on this project but just too many barriers kept popping up. I plan on doing that when I do a BBK next winter. I'm curious, did you weld those braces in that you put the mounts in or are those part of the original frame. I have something like those on mine but they looked a little too thin to trust. Also, what kind of a welder would you recommend for a noob? It seems like the MIG type is mentioned more than anything else. Rich

They are the brackets that the motor mount was attached to. I figure that they were the only thing holding the motor mount and engine before so they should be able to hold just the engine. I used the original bolt but had to make new spacers. You don't want any side load on the engine mounting tabs. I cut steel tubing to the approximate length I needed and then ground the ends down a little at a time till I had a snug fit. As far as welders go..I was told that if I was going to teach myself to start with a stick welder. If you can take a welding class then a MIG is nice. The best is a TIG welder. A good stick welder can be updated to a TID welder with the addition of an ark stabilizer, TIG torch, and shielding gas regulator.

Thanks for the advice on the welder. You're right about the lateral load on those mount ears, I've looked at those things till I'm cross eyed and they're just designed for pivoting and thrust on the scooter. I do think one can get a little too paranoid about what the mounts have to do, the main weight bearing is on the wheels and shocks. Also, we're dealing with ten HP max here, it's not a crotch rocket. But I'd sure as hell not want the mount coming loose on me. When I redo my Sino-mount I'm sure I'll over engineer it. Hopefully I'll have a welder and some practice by then. Rich

Its a pretty good welder. I bought one a couple yrs ago for a project I was working on. Do like a lot of the reviews say and get some new wire for it. The stuff that comes with it is crap and you wont weld very good with it. The only other thing I would suggest would be to replace the ground clamp with something better. Oh, and go ahead and spend the money on a shield that will autodark and fits on your head. Its alot easier to weld when you have both hands available. Dont get the goggles, make sure its a shield or you will end up with some nasty deep skin burns.

Progress report. Still waiting on parts. The battery box is the critical one. Once I decide where to mount it that will help determine where I put the shock mount, wiring (will be inside frame tubes), and seat. I'm working on the rear signal light today. Hopefully I can post pictures latter. This is a little hint of the plan for the next naked scooter. Think 4 speed automatic using the original CVT, 125cc air cooled engine, and a jackshaft.
