What are you people on here for if you cant help anyone

^ Why are you getting upset? We are here to help you, but its hard to know what to say, when you give such a description as "it just wont move" Have you tried to do anything on it? Its not going to fix itself. Check the obvious - you said it had a chain 3 years ago - check it! Make sure it is still there, maybe someone stole it, or maybe it came dis-connected! Are you shifting the right way? You need to move the shifter up for all the gears. If both of these fail, make sure the shifter is connected, and turning the shaft that comes out of the motor when you move it up or down. I know the YT's have the goofy linkages, connected to the shifter to the shaft. Make sure they havnt come loose, or dis-connected. These are all some good starting points. Its a lot harder to tell what is wrong hearing about it, and not seeing it in person. Good luck, and dont get upset, we are all trying to help!

If the shifter goes through all the gears and it doesn't move at all, maybe the clutch is burned out. Or it could be the shifter is broken internally and not allowing it to go into gear. But usually you can feel that the shifter doesn't feel right. But if you can push start it then the wheels and the engine are engaged in some way. Is the front brake locked?

Once you narrow it down more people can give you a more specific answer.

Can someone identify the ports on this carb? It is off of an 82 yt125. I have figure out the fuel and oil....but there are a few I am not sure of. Also, does anyone have the adjustments for the mixture screws and internal pilot within the float body? Any help is appreciated.

Here's a good idea, why don't you do a search on here for what you are looking for. There have been many threads and replies covering this same topic. You should be able to find all the info you want by just taking some time and doing some looking around. Trust me, there are plenty of pictures as well as to what the ports are on your carb. As for your trike not moving and you not riding it for a year, it could be many things. But mostly, since you have the trike and we don't, you ought to take the time and try doing a little fact finding mission by looking closely at your trike and see what is turning and what is not. Check to make sure you wheels turn freely-bearings. Check your chain, make sure it's not all rusted to the point where it won't move or maybe that it busted the master link and has fallen off. Or try adjusting your clutch. Most people on here have looked over and tried a few things on their trike first instead of just coming on here and asking what the problem. If you tell people that you have already checked over certain things, then people may be more willing to put their thinking caps on and make an attempt to give you some suggestions. But when the best thing you can say is the chain is fine since you rode the trike a year ago, well, then it's really hard for people to be able to take you seriously, at least me for one anyway as I shouldn't speak for anyone else. If you really want help, help us to help you.

I believe you are getting confused with the first guy......read the post from BENNETT. As for the searching...I have already went down this road. I have found some stuff, but the few I found did not answer the question. They were responses such as " I believe the black connector is crank ventilation" I was hoping for someone...possibly a yamaha guru to help me out. Anyway, This trike is the same model I used to ride when I was a kid....so far I have restored compression by freeing the stuck rings and it is actually running great and idles fine. But, It is peppering oil out of the exhaust and I believe it is running too rich. I am hoping for someone to ACTUALLY help me out with the adjustments and tube connections. The tube connections I am worried about are the two black 90 degree and the bottom float bowl connection. Don't know where they go.

For those of you who would like to know a nice trick for removing stuck rings and hard carbon....boil the assembly in a pot of water. Works like a charm. Make sure to give the piston a good coat of oil afterwards.
