Reviving an ATC110

[MrGiggles]

I recently found a Honda ATC110 on top of a junkpile. I ended up taking it home for free, and have a few questions about possibly reviving it.

First is I need to find out what year it is so I can locate parts diagrams for it. Where is it located on there? It does have the larger style alternator though, as well as a headlight and H/L lever.

Another problem is that the engine is stuck. I figured this and I have the piston soaking in PB blaster. I took off the recoil and it looks like it could be stuck by the generator. It did have a spark plug in it so no water got in the piston I think.

How hard are the igntions on these to troubleshoot? I have not checked for spark yet because the engine is stuck.

This thing is going to need a lot of work, if it is going to be too much work or money I will part it out. The fender on one side is gone, shifter is bent. I will try and take some pics.

Thanks.

if you need to know what year it is...theres a couple vin number decoders you can use. http://www.atvstyle.com/index.php/atv-vin-number thats the one i use

other then that....i dont know much about the 110s....ive never used pb blaster to free up a piston...ive always used mystery oil, but i guess pb will work fine. other people on the site could help you out with the other stuff

o yea......welcome to the site!!!

Welcome to 3ww.

the vin is on the front of the frame on the left side of the the neck where the handle bars are. Is the headlight round or square? on the left side of the motor there is a black cover with two screws holding it on. on the cover does it say 'CDI' or is it blank? take the cover off if its blank to see if it has points. If it has points it will be a 1979-1980 model. I think honda switched to cdi ignition system in 1981. If it has CDI ignition it will be a 1981-1985 or whatever the last year they were produced. the 1979-1981 had round headlights also a 6 volt electrical system I believe. the 1982-1985 had the square headlights and a 12 volt system. the 1983 model was the last year for the rounded type plastics and the 1983-1985 had more of "squared off" plastics. I believe in 1985 the airbox will be square. on the earlier models they were rectanguler.

I have a small update. I did get it to free up, not sure what was stuck. It has hardly any compression though. The valves are actually in spec and being held open so they are okay. I could get lucky I guess and the rings could be stuck in their groove.

I also did a spark check and it has none. The plug does have spark on my Bayou. Where should I start troubleshooting the electrical system?

The headlight is round and it has points. The VIN is TBO2-2075175. I'm going to clean the points and see if it has spark then.

Update:

Cleaned up the points and it has spark now. I still have a couple questions.

1. On the recoil it seems like the rope is stuck around the spool. I have pulled on it as hard as I can and can't get it to come out. I cut the knot off that holds it in BTW.

2. The back wheels are stuck solid. Where is a common place for them to stick? I have verified it is neutral.

tear it down,take everything apart and clean,grease,repair,and buy what you need.

Sounds like that trike has sat a long time . the recoil will probably need to be taken apart and just force the rope out and do a rebuild on it .
A-lot of trikes with drum brakes when they sit for a long time the brakes shoes come unglued and jam themselves in the drum . your just gonna have to take the back end apart and install new shoes .

How hard is the recoil spring to put back in?

I will check that out when I get the recoil sorted out.

I will tear apart what I have to.

If you let the recoil unwind , remove the C clip and just wiggle it out it you might get lucky and the spring will stay in the housing .

I won't be able to unwind the spring all the way because the rope is stuck. I will probable give that a shot though.

Once I get the recoil fixed I just have to clean the carb, get the throttle cable unstuck, and put on new fuel lines and I will be able to see if it runs at all. If it runs okay now I might hone the cylinder and put in new rings,

There's a manual here.

my recoil on my 200 was acting up, I took it off and sprayed the hell out of it with some WD40 an let it sit all night. put it back on the next day and all has been well ever since
