67c2tr upgrades /cdi

[m in sc]

few things on this I've been wanting to take care of, for years.

1st thing was the ignition. always wanted a cdi on it, but the crank end is an odd size. bought a vape for a ke125 and while the stator works, the stock crank taper is smaller than most. its a 3 year 1 model motor, so odd.  working with economy cycle and vape directly, a suitable rotor was decided upon after test fitting and me 3d printing different taper adapters and relaying I info back to vape directly . the rotor that will work will be on way next week. 

also, I bought all nos rear sprocket parts to replace the stock dual sprocket setup. tgis is a weird one, so I thought olid post up a few pics of the new bits. yes, the large sprocket moves out for offroad gearing.

re: dual range sprockets. Always wondered if alignment between CS and rear sprockets would cause a chain problem? Seemed like a good idea at the time but wouldn't it necessitate carrying a separate length of chain + Master links to change on the fly when you are out and about. Would kind of take the cool factor out of it for me.

it came stock with them, the extra master and section of chain. the large sprocket is dished so as you tighten the 4 bolts up, it lines up. its a bit manual & rudimentary, but very clever.  I never use the big sprocket but have ridden w it. its a wheelie machine in 1st gear and won't go over like 30 mph maxed out in 4th. lol ive had it sort of off road once, its dismal in anything but a relatively smoothed paved area.    lets be honest, its a mid 60s designed camping bike.

Very cool

Now that is way before my time and a first sighting for me. Very unique motorcycle and pretty to look at. I imagine in this day of age it must draw attention from all age groups. So how fast or rather how does it scoot along using the smaller rear sprocket?

[m in sc]

you and me both, i was negative 5 when that was built.    itll do 60 pretty easily, will hit 65  its a 4 speed and has the rotary shift pattern or n-1-2-3-4-n-1-2-3-4 and so forth.

its actually 115cc. weirdly the g series went to an iron cyl in 1970, this ones aluminum, and honestly just better.  its a tiny bike but it gets attention for sure. I've owned it since 2013.
