New trike owner (yamaha). Help?

[TheCamaroGuy]

So I'm new here, and new to trikes in general.
I just picked up a Yamaha 125 and 175.
The 125 (tri-moto?) runs, but I can't seem to be able to pull start it, it just won't fire. But the guy drove it here and said he push started it. How do I do that, and can it be done with just one person?
The 175 tri-moto is in parts at the moment, and the engine needs to be rebuilt. After suffering multiple kick-backs from trying to start the 125, I've decided I want a kick start. Is one easy to put on? And the foot pegs are also broken off and one missing, can I buy new ones?
And what kind of mods can I do to these things. I would like to get more power out of my 175 for sure, but what can I do, and what can be done to them other than motors.

Thanks for any help guys, I've never even driven a trike before, so I look forward to taking them for a ride. I hope I like them.

to push start trailprotrailpro bike have it in nuetral then when u get it goin like adown a hill works good slam trailprotrailpro but down on the seat and pop it into 1st gear at the same time and it will start

[CRAZY70MAN]

Welcome..... awesome sight for new triker!!! These guy's will help you out with all of your needs. As for the push start, you can put it in neutral and get some momentum....jump on seat and put it in gear at same time ot put trike in a higher gear with it switched on and begin pushing that way? It would be easier if you had a buddy or your wife...:lock: :lock: :lock: just joking, push you while you were on it just to get it running. Sorry, don't know much on the Yamaha side of thing, Honda 70 freak here..... good luck and welcome.:beer :beer :beer

spray some quick start in the air intake it will fire the first pull mostly likely.

[old-yellow]

welcome to the boards and if you need parts try posting in the ATV classifieds forum or checking on ebay.

[old-yellow]

Oh yeah, try cleaning the carb and putting a new spark plug in it also check compression, if you still can't get it to fire try pull starting it behind your 4 wheeler

[yamaha_ripper98]

some models if you hold up on the shifter it wil be in a neutral then let off and it will go in...... the higher the gear the easyer to push and turn over i donno much about the moto's but my 225dx does this shouldnt be as bad on a 2 smoker tho less compression

[trimoto.125]

I have started my trimoto 125 a different way before. Put it in first, grab the rear grab bar or axel pick it up push it for a few feet drop it.Works good when you don't have a hill.

[TheCamaroGuy]

Thanks for the help guys. I'm gonna give those a try. I'm looking forward to some warmer weather to start working on these things. Gotta get rid of the yellow.

EDIT: If I get you guys the vin number off the front, could you guy's tell me the year, ect?

[yamaha_ripper98]

If the 125 is kicking back alot when you are trying to pull it over, its possible that the timing is off. I don't think a kickstart can be put on a 125 or 175 trimoto engine. As far a mods go, you will have to talk to vealmonkey or someone else on the board with a tricked out trimoto.:TrikesOwn

[TheCamaroGuy]

I will make sure to check the timing when I get it running. And I'll post up pics next time I see the thing, it's sitting in the back of my bronco right now (kind a tight fit lol).
And I'll make sure to send him a message.

[brapp]

if you want kickstarter look fo ra comlete it175 motor its abotu your only option and you pick up a manual clutch too.

Does that come off of a motorbike?
And here are some pics, I'm assuming the guy before me swapped the skins and front end, because the one that says 175 is actually a 125.
The 175 right now is in parts, I just put the wheels on (gonna bolt up the front end tomorrow as long as all the bearings are there)

The 125 we were going to try to start today, but the tires are low on air, and it was too cold for our old compressor to start up

[daniel_250r]

haha i'm liking the pegs welded onto the forks for cruisin

[TheCamaroGuy]

Lol yeah, I'll be grinding those off next time I have the grinder out.
How easy are 175 front forks to find? I definetly want some front shocks on this thing.

[old-yellow]

Looks like you got your self some decent trikes on your hands, you going to love building them up to there former glory. Also if you need parts post up a wanted ad in the ATV classifieds I am sure someone is got what you need laying around and if you need help getting them to run let me know and I will try and help the best I can. By the way there a blast to ride especial when they got front suspension.

[TheCamaroGuy]

So I got the 125 started (it was slippery so putting it in first didnt work. So we push started it in 4th (yes push lol), ran it for a few minutes, then I didnt adjust the choke and it stalled. Couldnt start it after.
And the 175 is missing more parts than I though.
So far my list is
Need: choke cord, brake handle, steering ball bearings, pull starter, foot pegs, and whatever to make the engine run.
Could use: Seat cover, brake cables, handlebar grips (fox), Tachometer (anyone know the redline?)
Want: Front shocks, new handlebars (fox?), paint job.

I'm a big fan of fox racing equipment, but have not been able to find what all they make that could be put on a trike. Does anyone know, or know of an online catalog?

[TriMotoMan]

you should pit the two bikes together and get one nice one

[TheCamaroGuy]

No need, the 125 is a good trike, minus the starting/runing problems. Doesn't really need anything other than that.
And he 175 is my little project, gonna build it up beyond stock. Turn it into something I can race around with.

[old-yellow]

Mine would do the same thing in till I discovered That the carb was getting clogged with very fine particles of sand, So I put a fuel filter on it and cleaned the carb again and it solved my problem also set the carb air/fuel mixture screw to 2 1/2 turns out from closed and If you got any more questions about specifications I own the repair manual also have you tried checking compression on it, it might need to be rebuilt.

[TheCamaroGuy]

Thanks for the links. I saw the rear suspension one already, and I am very interested in trying to find a kit like that after I get back from paris and have some cash.
And my 175 came with a repair manual. Would the 175 and 125 manuals be closely similar?

[old-yellow]

It should be pretty close except for the carburetor,cylinder,head,piston and exhaust other then that, they use the same parts in the lower end and on the frame.

[TheCamaroGuy]

Okay thanks man.
I noticed the exausts are crazy different. is the 175 alot better? is there one i could put on to get some more hp?

[old-yellow]

Yeah here's one I seen on ebay even though it says for the 125 and 175, They do not interchange because only a 175 pipe will fit on a 175 engine and only a 125 pipe will fit on a 125 engine, If I was you I would put all my money into the 175 to get it running again.

[Howdy]

Too bad you don't live close to me. I would hook you up with a bunch of parts for the 125 & 175 cheap. Shipping would be a killer though.
Howdy

[TheCamaroGuy]

That would be sweet, but yeah it would be esp bad getting it over the border. But thanks anyways man.
And yeah most of my money will be into the 175, the 125 doesnt need much money, mainly just time.
Went to go order the steering ball bearings, $25 for the top an bottom, argh. Gotta see what ones I really need before I order them

Here's the links I use to find parts on ebay, you can try using your own this is just what I use.

Have you had any luck getting your trikes running again?

[TheCamaroGuy]

Tried the other day to push in 4th again, couldnt get it to turn over fast enough. And not enough energy to try again. Went home, thought about it, and I might have been in 3rd last time and thought I was in 4th, which would be why it fired then.
Might go try it in 3rd if I have the energy to push the thing this week.

[TheCamaroGuy]

Not yet, it's been too cold to do anything lately. -29c today. When it's nice out I'll htink about going out and looking at it.

[TheCamaroGuy]

So it was nice out today, and I finally found time to give er a go.
So we pushed the 125, poped the clutch and got it running (2nd try, not bad). It runs rough, It smokes, and we keep having to fill the crankcase with oil, could he two be related?.
We checked timing and it's on the first line (what one is it supposed to be on?), and coming from the carb there are like 3-4 tubes that come off of it but go no where.

I also pulled the rear plastics out of the garage for the 175 and started working on them. They were painted by the previous owner, so I took some time and started scraping and sanding it off so I can eventually give them a good paint job.
I'll have progress pics tonight of the fenders.

If you have to keep filling the crankcase with oil you have a bad right side crankseal or possibly the center case isn't sealed properly but more likely its the crankseal. I would replace both crank seals.

[old-yellow]

Sounds like bad crank seals and as for the carb there should be two breather lines at the top and one line on the front right side of the carb for the oil injection.

not sure on all the yt's but i have an 82 125 with an 83 175 pipe on it. i did this swap myself cause the 125 pipe was junk and the 175 was to far gone to try and rebuild. i had to have the flange from the 175 motor and made a short mount for the rear of the pipe.

[TheCamaroGuy]

Heres the pics of the skins. As you can tell I have only started on the one side. But its looks alot better than the rest already.
http://img.photobucket.com/albums/v77/bobthebrat/p_00035.jpg

I'm just ordered the bearings for steering. But if anyone has a choke cable for the 175, brake lever for the right hand side, or a good pull starter, for cheap. Message me up.

hey im kinda new to this forum thing but i just bought a yamaha 125 tri moto and i dont have it running yet but i dont think it needs that much work but im sure once i start working on it im gona find more problems with it but any way i just want to know more about them oh and i need friends on here 2

[chuk2695]

wow nice seat cover i want 1

[TheCamaroGuy]

Figured the 175 was too far gone to put more time into. Went out and bought another 175, perfect skins, original tool kit under the seat. The tires were bad so I swapped them from my now parts trike. It runs if I push start it, but the compression is at 80lbs, so I'm assuming too low as it doesn't like to stay running.
Tore the top end off (head and cylinder), and it looks like it needs to be machined (not too bad though). Took the top end off my parts trike and its a lot cleaner and the cylinder is in better shape. My new 175 is a 83 and my old one a 82, would all engine parts swap over? It looks like the ports in the cylinder are different.
If they swap over I'll toss it on, check compression, if it's any better I get a gasket kit for it and put it back together.
