Need some ATC110 advice

[Micahdogg]

I've decided that a few ATC90/110's would be good toys for the backyard. Upon telling a friend this, he said, "Hey, I've got one that you can have for free. Just needs a clutch."

So I picked it up. It's a 1984 and is fairly complete, except it looks like someone took the clutch apart back in 1995 and left it like that. I got it, and the bucket of parts home, and upon reviewing what I have, it looks like I need quite a few pesky things:

- Recoil starter (is gone)
- Air boot from carb to airbox gone
- No dipstick

The rest is all inside the clutch area. I'm missing:

- One clutch spring
- All four bolts and washers that go to the springs
- Gear selector arm up in the top left corner that keeps you held in gear (have the spring though)
- Need 3 new friction plates obviously
- All of the clutch actuator parts that go on after your clutch pack is installed, but I have the arm that mounts to the shifter shaft.

So this is it, doesn't sound horrible, but......I also know nothing about this motor. I removed the plug and put my finger over the hole while turning the clutch pack by hand. It didn't feel like it had ANY compression. So I don't know if it wasn't turning fast enough, or if the cylinder/piston is shot as well?

What do you guys think? I have never messed with any ATC110's and never even saw one in the flesh until I picked this up. I've just been going over parts and looking at online diaghrams and figured out what I'm missing. Is this thing worth saving, or is it a lost cause?

Sounds like a mess. Might be better off looking for a donor motor.

It doesnt matter how fast you spin the motor it should still have some compression even with your finger. It sounds like you should check the top end just to make sure everything is ok and check the piston and jug those are the main issues for compression. These bikes are always worth saving if you know how to do the work and these motors are very simple and friendly to work on. Esepcialy clutches. Get some pics up of the motor.

I am inclined to get this thing running.

One thing that is puzzling me about the clutch is the spring arrangment on the first steel plate. I've only got 6 springs, 4 long and 2 stubby. I can't figure out how it should all fit with the fibers and other steel plates.

Here is a bad pic of how I found it:

If you follow tblumer's scematics you should be able to get the clutch together. As for the engine were you able to find out any more on it.

tblumer, I assembled it that way at one point and it felt good, but until now I didn't even know for sure if these short springs were ATC parts. Thanks for the link.

200...I haven't looked in the motor any further. I was really hoping to just assemble the thing with new friction plates, pick up a recoil starter and see what happens. But it looks like it'll nickle and dime me before I even get to that point. I just noticed last night that I don't have the starter pulley on the stator.....and the stator nut/washer are gone too. Almost looks like someone was trying to pull the stator. That doesn't give me warm fuzzy feelings.

looks like a basket case. I would part out, save what you want & get one that won't give you problems. I have a running 90cc engine complete you have for free but I don't know if shipping would be expensive to ship an engine?

[Stonewall]

I think you can ship those engines for $25-$30.

Anyone know if a '79 90cc motor would swap right in? If so, would my 110 carb work ok with it or would I need to obtain a 90cc spec carb? I don't like the idea of removing the 110 motor, but if this will keep it from going in a junk pile then it might be a good alternative.
