Another desirable thing about a 212 is a power feed for lights and such. I don't have a schematic at hand but I am sure there is a voltage unknown power feed.

Well, that hidden shutoff switch would give newcomers a problem. I wonder if she still has it?Lynne of MBrebel had a brain f@rt on a 78cc Pred. She was a 2smoke builder. Somebody nicer than me musta showed her the ON-OFF switch. That bike and it was a nice one, ran when I looked last. She lives bout 1/2 hr South of me.

If she has a cassette on that bike I bet she doesn't have many miles on it. The Shimano cassette on my bike was not usedYup, she found the switch, and is a runner. Interesting set up. Rear single speed cassette freewheel.

Lynne developed a (system) probably pirated from some one else that incorporated a drive sprocket and brake disc on the left side of the hub, meant for just a brake disc. She had a built wheel somebody returned with a cross threaded broken screw in it. Lynne gave me the wheel to do with what I wished. I had been providing machine shop services for her.If she has a cassette on that bike I bet she doesn't have many miles on it. The Shimano cassette on my bike was not used
for shifting it was used as a single speed bike and the 212cc buzzed the bearing out at a little over 500 miles on it.
The bigger single speed bearing assembly with a coaster brake would have lasted longer and that's the reason I went
with the mag wheels with sealed bearings and they haven't given a minutes problem since.
I suppose it was a jackshaft end with a disk rotor for braking?

Got the broken screw out easy. Rethreaded the 6x1mm to 1/4-28. Cassette was only ever meant for pedal drive.

ah bummerRocket, you can’t run a headlight from the oil sensor wires.
The sensor is a simple “open seeking ground” switch. Probably filled with mercury. When the switch is tilted, the mercury connects the end and center contacts inside the sensor and shorts the coil wire to ground.
This turns the engine off.
Thanks 5-7Heaven, I was wanting to put a minibike headlight on my bike and maybe a "SuperCap" to hold a charge so the headlamp doesn'tFor $20 on eBay, you can buy parallel charging coils for your 212 engine. It bolts directly onto your engine block, replacing your single ignition coil behind your flywheel.
It’s designed to run a headlight from it.
oh perfect. I'll go buy one now.For $20 on eBay, you can buy parallel charging coils for your 212 engine. It bolts directly onto your engine block, replacing your single ignition coil behind your flywheel.

I take it the OEM is a tapered shaft if I got this right?The dual coils will work on an OEM flywheel, but not with an aftermarket aluminum flywheel.
Another thing, the aluminum flywheel is meant for racing only in rpm ranges exceeding 3600-6500+ rpm. Like the old high-performanceI take it the OEM is a tapered shaft if I got this right?
