Hi All!
I just want to thank you for having an active forum, with a wealth of info.
I bought a CMO10 (China) ct70 w/ a 90cc 4-speed auto elec. start.
I have no idea who made the engine :confused:
It came with one piece alloy wheels, so no disc brake kits :(
I've ordered the 17t front sprocket. Can't wait to put it on.
It's gun metal grey in color and had 178 miles.
Mods I'm looking forward to:
Raising the front fender.
Michelin Reggae tires
OEM skid plate
4-speed manual engine w/ more cc's and electric start. (after I wear out this one)
Q; How big a motor, before you have to mod the skid plate or front fender?

Nice to have you here! Bike sounds very nice.

I just put a 140cc on my bike, didnt have to modify the front fender at all, I dont have a skid plate though.

I saw your 140cc project.....super:cool:
I think the electric start is one of China's best improvements:eek:
My kick starter pushes my foot off the peg so I'm going to get the strait style for that.
I was wondering about the raised fender.
I was thinking of using the Dax style from R-Designs (euro)
Has anyone tried this one

otherwise I'll go with
CHROME FRONT FENDER CT70 K0_TO_1978
I understand the bigger tires will not fit with the low fender.

How big a motor?

I have a 110 Honda Nice motor and the OEM spark plug guard/skidplate fit fine, a little snug but bolts on just the same. I would strongly suggest this especially if you plan on riding "off-road" at all. Good insurance.

You might want to keep an eye on the rear hub, in the area of the snap ring retention groove. There's a surprising amount of sprocket movement on the hub, enough to "walk" the snap ring 360 degrees. Some Chinese hubs have a ferrous metal snout integrally cast into the aluminum, as do OEM Honda hubs; some do not. Aluminum is too soft for the application, can wear rapidly & break. A magnet will tell you if the hub is all-aluminum or not.

Kawasaki-knockoff motors have larger upper engine mounts than Honda used and the frame must be cut to clear the engine in that area. Some of these engines have much larger external dimensions than anything Honda ever produced for a bike with the Z50/CT70 engine mount pattern. Thus, you'll need a different footrest assembly, including kickstand and the stock engine guard very well might not fit. Any Honda horizontal engine with Z50-pattern egine mounts will coexist with an engine guard, regardless of displacement as will most Chinese engines that are copies of Hondas

With a low (fork leg) mounted fender, it will depend on the specific bike and tire size. Some guys run 120/90 x 10 tires which is the limit and a lot taller than stock. Extending the fender mount brackets isn't too difficult, but with a tire this tall you'd need to keep the clearance very tight to keep the fender from hitting the lower fork tree should the suspension bottom-out. For that reason alone, an OEM Honda fender, mounted directly to the lower tree, might be a safer bet.

Electric start is strictly a matter of individual preference. They're only to be found on Chinese engines, unless you can source a Tiger 120 from Thailand.

Great info, Thanks for responding.:D

I just installed the 17t front sprocket. It came in today's mail.

What a difference! I really like the shift points, and no fear in city traffic. It still pulls steep hills with my daughter added (I'm 220lbs). but I do have to shift down to 3rd on the steepest :red70:
My speedo broke @ 200mi. so I'm guessing it's pulling about 45mph now, sounds so much better using the lower rpm'
I still have the 42t rear, but the 17t really makes the bike work for me.

I'm pricing the Reggae tires locally so I will need a fender soon

I would like to replace the speedo, but I think most of what is available is the same Chinese one, that just broke.:(

I might buy another bike for the manual gear box, and save the auto for my oldest daughter to ride and friends to ride when they come to town

I should have pulled the rear wheel to see if it has a steel liner for the brakes, but i would shocked to think the pads are pressing on a bare aluminum hub :eek::eek::eek::eek:
