Is the tri moto 125 the biggest peice of junk ever

[rustbucket]

I am certainly inclined to believe it read my classified ad All it needs is a crank seal. Which i have. but one question do i have to split the case or will it come out without splitting looks like it might but i'm not sure.

[KayodicWeazel]

To answer your topic title, yes it probably is, second only to my 110. To answer your question, I dont really know.

Both sides can be changed without splitting cases, stator side is easiest need puller though, but other side side case comes off, clutch pack also so you can remove gear on crank to get at seal. But these aren't junk, just do a little maintenance before it brakes down all the time, Check crank bearings when seal is out for play if loos you might as well overhaul everything while your at it and it will run forever again.

The YT125 is an awsome hardtail trike. It'll beat the pants off any hardtail honda thats for sure. Anyway, I've found that the desire for any trike is not so much dependent on the price but more or less on the location. There is probalby someone on the board who would love to have it but ios too far away to make the purchase economical. I would love to have a YT125 again and sounds like you only need a simple fix. Unfortunatly michigan is a bit of a drive for me :-(

Yeah I have the seals. I got them with the gasket kit. See I re ringed it last summer but it died shortly after and i noticed that the bearings were smoked but i had another motor that had been rebuilt but thyey run it alot and hung a ring in the port and roached the piston so i figured I clean it up a bit and put my new top end on fired it up and for a bout a minute it was fine then the seal tore and it started to suck in tranny oil and smoke real bad worse than a worn out diesel tractor. But since i can change it with out splitting it I bthink I'll get on it soon.

They are far from being junk.

[edog]

I agree i have heard alot of good things about them.

I think I got a lemon here. I put new seals in , the old ones had popped out and were hard as a rock. Fired it up rode it a little and still smokes real bad and no power can't go any higher than 3rd It will load up a minute then you down shift and gas it and its fine for a while. This is the same crap it did before a redid it and it was a different motor. I think I may have to set it on fire on roast hot dogs over it I've seen johnson snowmobiles that ran more often than this thing.

Man, I wouldn't admit to letting a bone simple air-cooled 2-stroke get the better of me. Work it out.

[Louis Mielke]

heh. no hot dog fodder, hell i'd fix it for free for yah. Common get serious about it. What does the plug look like, is it lean or rich, get back to basics. Sounds like something simple.

Other than preventative maintenance, all I do is put gas and oil in my Tri-moto 125. Awesome little trike, and I beat the crap outta it. Sounds like "operator error" to me! (just bustin)

All right guys heres what I know None of the gaskets are leaking (head, base,tranny) Because they are new and theres no eveidence of it. Plenty off compression since the bore is fresh. I have brand new seals in it I put them in yesterday. both sides. If you pull the cord it usually starts but it won't idle well so i stomp it in gear and go you can shift a couple gears 3rd is the highest before it really bogs down but it will do it in first and second. It smokes really bad and not good smelling 2 stroke smoke either. It looks like a car I used to have that went through 1 quart every 5 miles. When i ride it theres a big plume of white smoke. Alos if i turn it seems to have a negative effect on it also. when it starts to die i let off stomp it down a gear and go and its fine for a few minutes. When it did this last summer i had a totaly different motor in it that had bad crank bearings that wopped out the seals. I had changed cdi box and coil and carb with no efect Maybe I have the oil too full and its building pressure and forcing it past the seal?

[LonesomeTriZ]

Even with all that going against it, it still runs.

Junk? I think not.

[kando]

How full do you keep transmission? you said maybe its too full? Don't you run it at the oil level bolt hole on side of tranny case, just pull bolt out and fill till it just starts to run out. Don't know if this is your problem but if you way overfill it who knows.

Ok, if anyone still thinks they are junk, read this post I made awhile back. http://www.3wheelerworldforums.com/s...ad.php?t=34432 Long story short, I ran it WITHOUT OIL for 3 tankfulls, and it kept right on running. Still runs great.
