honda atc 200 but which one?

[MisterRoboto]

i just got this atc today

cant seem to find a vin on the neck but i found this serial on the engine

and this on the frame

tried to use the decoder online but it wouldnt take this serial number
anyone know the specific model for this one? is the engine not original?
thank you very much

[RDH/86200X]

Looks like an 83 and its got 83-85 200x rear hubs and rims on it.

Pretty sure it is a 200M. According to the vin decal, it is an '84 or '85 model (depends on the month it was produced).

[MisterRoboto]

according to this thread the engine serial is an 83 200x? or am i reading that incorrectly?

should the vin be stamped into the neck or was it a decal/sticker on the neck?





also if it helps the identification my engine does have high low and reverse.
what is the lever on the head on the right side near sparkplug/valve cover?

[MonroeMike]

Is it shaft or chain drive? (I can't tell, my monitor is too dark, even on the brightest setting).

You may have found an error in the serial numbers, I double checked the manual(s). I copied it correctly, but their info may be wrong. I will update the page, after this is figured out.

You "might" find a VIN by taking a wire brush to the circled area.

The lever on the head is a compression release that allows you to use the recoil starter while still retaining full function of your rotator cuff. I see parts from a few different trikes on yours. The tank looks like it came off an S model, and the forks are from a 200M model. If the trike is shaft driven, the engine and frame are from a 200ES model.

Looke like a 200 es

[MisterRoboto]

it is shaft driven


wire brushed it some and didnt seem to find anything.


my main concern is finding out what engine it is so i can get some gaskets and prob timing chain for it



i really appreciate the help guys thanks

If it has hi/lo/reverse then the engine is a 200ES. Looks like someone frankentriked it with a tank and forks off of other models.

Edit...

For some reason when i was on my phone earlier i didnt see the above post with the added pictures... Definitely a 84 200ES motor at least! The rest seems to be bits and pieces from other years.

having a real hard time getting the bottom engine mount bolt out.
there is no way to remove the head without taking the engine out of the frame is therE?

searching the net i found another post on this forum in which the guy needed to get a broken exhaust stud out and instead of removing his engine he could remove the head studs to get the head off. so i think im going to try to do this before continuing to remove the entire engine... wish me luck

The engine is defiantly a 200es

Pull the motor to work on it, you will be glad you did in the long run.

DONT remove the top end studs... You can't anyway unless you pull the top end off most times. If you unbolt the rocker cover you won't have much stud to work with to get a hold of, and chances are you will just break one or rip the threads out of the bottom end. They tend to collect moisture and get corroded into the cases, i have had to pull the top end and soak in PB Blaster and apply heat from a torch to get them out before.

I have unbolted and removed the motor from a 200ES more than a few times now, its a pain but better than breaking something. To get that bottom bolt out get a long punch, aka a drift, or even a long philips screwdriver if you have one that you don't mind pounding on, then just it out. Once you get them all out before you put the motor back in clean everything and grease the bolts!

Edit...

Looked at your other pics, thats odd there is no VIN on the side of the downtube, there is on every one i have worked on. I am guess its not an 84 200ES frame but rather something else someone cobbled together. I think some of the other years had just a sticker, which would explain why yours doesn't if they took a frame from another year/model. Just guessing though, but that spot you wire brushed is where the VIN should be stamped in for sure!

[MisterRoboto]

i might take your advice and continue to try and get that bottom bolt out. i tried pounding it out for probably an hour with a socket extension and it wont budge -.- rusted in there real good i guess i was going to take the studs out to avoid removing the shaft drive as ive only ever had 1 other atc and that was when i was 13 so i havent worked on one yet


went and beat on it for another 15minutes. wont move... tried to double nut and remove one of the studs and i did not like how it felt so now im not sure what to do. i have an air but not a good attachment for it maybe ill see if i can find one that will work tomorrow
wish me luck

I think the serial number is stamped on the right side of the neck and the sticker was on the left

That is where the serial number appears on my 250es trikes.
The serial number on my 1984 200es is stamped vertically on the front right area (when standing in front of the trike) of the steering head tube, just under the headlight.
