A Crazy Idea, Advice Welcomed

Got the motor cleaned up today. Was leaking oil out of the left (alternator) side and had a lot of caked on greasy dirt, as well as that white chalky crud on the fins. I'm hoping the leak is just the crankshaft seal being shot. A new one should be here on Monday. A new battery is on the way and it's 5 1/2" x 5 1/2" x 3" so that battery box has to be pretty large and sturdy. I'll use the holder from the CM250. but it'll need a box-like cover which I'll fabricate from sheet metal. I think I'll use the levers and throttle off the CM250 as well, though they'll look a little goofy on such a small bike. But goofy is almost the same as crazy and that's what I'm after.

Modified the rear fuel tank mount, raising it about 3/4". I had to remove part of a fin on the head, so now the fuel petcock does not interfere. Also found that since the 250 motor and its exhaust is so wide compared to the CL90 frame, the brake lever had to be totally reworked. Ended up cutting the one off the 250 in four places, welding and extending it. Also got the drive chain mounted and geometry looks good, chain tension hardly changes with suspension movement. All in all, a good day.

Just a few odds and ends today. Installed brake pedal, rod, and now has brakes. Installed both sets of switchgear and levers from the 250. Hooked up front brake and clutch cables. Also installed the coil, barely fits under the tank. Then I gutted the headlight bucket of most of the CL wiring I won't be using. Tomorrow, I hope to start installing the 250's wiring harness.

I wonder if the front end from the 250 would be a better option for handling and the extra weight

The CM250C as a whole is much more of a real motorcyle, bigger and more substantial in every respect. Most parts (except the engine of course) would look out of place. If it had a front disc brake, I might have considered something. Now that I am starting to adapt the wiring harness, I've run into some issues. First, there are so many electrical parts to attach to the frame and making them look like they belong is a challenge. Secondly, the harness is thick and has turns and bends that don't fit the contour of the CL90 frame. I'm considering removing that vinyl bandaging that surrounds all the wires and redoing it.
