Hi everyone,
Just picked up my next little project - a bit of a relic but great fun hooning around this hills. Still runs fine and didn't cost me very much (my dad has just retired and was clearing his sheds and decided I can restore this one and he will restore his beloved TS185).

Now the frame says CM75, but the only model I can find that is similar is the TS75 from 1975 (thanks to suzukicycles.org). 72cc air cooled two stroke, 4 speed manual. Almost identical to a TM75. I am assuming the "CM" prefix was a country specific thing. No idea of HP or anything like that - but blasts around at about 60 or 70kph which is good fun, and only weighs 78kg so I can handle it pretty easy.
Anyone out there ever come across one of these? I am particularly interested in sourcing a carb gasket kit and new brake pads to start with. I will probably also need to sort the clutch out as it is a bit sticky (although to be fair it has been ridden much over the last 15 years). If I can get an idea of commonality to other models it will widen my chances of getting this thing back to shiny new.
More pictures will follow once I get this underway... :icon_mrgreen:
Wow. I was 8 years old in 1975. I can't say that I'm familiar with that exact bike but it looks like almost every minibike that kids around my area had. Really cool project...
That definitely appears to be a TS75. 5HP (appx). Check here:

Maybe you are correct about the CM75 being from another Area. (Overseas, Canada, etc ?? )
Project update:
Managed to source some compatible TS75 bits including:
- Clutch plate set (arrived)
- Brake pads (arrived)
- Fork boots
- Muffler
- Tail pipe (arrived)
- Condensor + Contact points kit
Have got my eye on a replacement tail light, there seem to be some "new" ones coming out of Thailand - anyone had one of these on a restore job? I am suspecting the chrome is probably going to be fairly average / rubbish... may be better off sourcing an original and getting it re-chromed along with the bars.
EDIT:
Just found some information on the CM75 - may have been a Japanese model only - Suzuki Minikuro CM75.

Restore job in 1997 by the looks of it - (did a basic translation with Google) looks like a neat little run around with road tires on it.
Well it has been a very hectic few months with a brewery project for my degree, but I finally managed to spend a few hours getting the bike running nicely.
First order of business was the clutch - bit of a procedure with the TS/TM/CM 75
- Drain oil - note that oil has become milky grey... know why the clutch has seized..
- Disconnect air filter hose and remove front engine support frame
- Remove kick starter and foot peg
- Locate every screw on case - loosen with impact driver
- Disconnect carb and remove yet another case screw
- Tap every edge of the case with block of wood and hammer
- Remove bonus hard to find screw that resides below the carb where you can't see it
Finally get the case off..

Note that the old clutch is well and truly seized.

Bit of a trick with the older clutch baskets that don't use bolts - gasket seal hook works well

Replaced with the NOS clutch kit (soaked in oil for a week) - replaced main gasket and buttoned it all back up. Had to readjust the clutch cable (getting a bit stretchy but not quite gone). Filled the Oil (700mL)
Replaced the points (27.5mm flywheel tool required) - set gap at 0.2mm 20 deg BTDC
Replaced the spark plug
Replaced the brake pads (old ones just have a hard glaze and have been saved for re-furb)
Bike now starts first kick with a small amount of choke when cold. Clutch is nice and smooth
Will hopefully post a few more photos in the next few weeks - more importantly I hope to take it out for a spin :cheers:
