Tri-moto 175 Oil line Q...

[MTS]

Hey,
The three lines in the pic, im assuming are for the oil injection? at least the 2 right behind the cylinder, and what about the yellow one? it come's from a fitting behind the crancase fill.....I need to know so i can block them off (oil injector craped out)

Thanks

yes, I would like to know the exact same thing hope someone can help us.

the 2 black ones are the to the oil pump itself. Cant tell where the yellow one goes in the pic. Theres a vent about 2 inches to the left of those black lines under the jug fin that shouldnt be blocked. I know what youre talking about now. The little tank on the back of that case with the black cover. Thats an overflow tank. Dont need to block that off.

Did the oil pump crap out--???---Or---

That cable shouldnt be kinked like that--the yellow hose just gets stuffed up in your frame tubing where it sleeps Fat dumb and happy---It has to stay unrestricted -----the other port at the end goes to your bowl vent

[yt175]

i beleive the yellow hose is the crank breather hose

Wich one go's to the bowl vent? and i kinked that cable i think...haha but from the looks fo the motor it looks like the pump died, im not takin any chanc's ill just pre-mix it :beer

[Unclediezel]

there is a small triangle box at the bottom of the right side case---with two ports on it ---one goes up into the frame tubing---the other goes to the bowl vent on the carb-----(The little black 90 degree plastic fitting)

The breather hose is connected to the fitting just under the jug fin.

There are little black 90 degree plastic fittings on both sides of the carb, Arent those for the oil injection? YT125/175 models have an overflow chamber attached to the lower right side of the engine.

[Unclediezel]

Exactly-----correct!

The oil injection goes on the side of the carb--Direct port into the throat--It doesnt get mixed in the bowl

[Unclediezel]

Josh- If you can take a new pic and just move down a bit so the bottom edge shows the vent box---I'll draw litle arrows and such---its tuff to explain----without being able to see the whole pic

[Yamahauler]

Did you get the crap cleaned out of your carb yet? That thing should be running by now!

[holmstrom]

heres 3 pics of an old bottom end. you can see the crank vent now above the oil pump hoses. The black end is off but at the bottom left of the case is the overflow chamber.

Allright,....Now the oil line injection is on the throat of the carb, bass fitting,,,,i gota plug that,
Also that Vent under the jug holstorm, that hose go anywhere perticular or dose it matter?

[holmstrom]

the 2 black fittings on the carb are the oil injection. The vent i just ran a hose out the back. I also when i changed my crank seal, took the gear and shaft off inside the case so its doesnt spin my pump anymore.

[Unclediezel]

holmstrom----

The two small black fittings are the bowl vents------!!!!!!!!!
The oil injector is the single brass fitting directly into the throat----If you push oil into the vents while they are expelling air--the oil wont mix --you will starve the motor--eventhough it no longer matters cuz your pump is inop---Just think for a minute---What stops the gas mixing with oil--instaed of oil mixing with gas--It sounds the same --but has very different results

[MTS]

OK so i need to or dont need to plug the black 90 degree fitting on the carb?

[Unclediezel]

They must remain unrestricted--or else your bowl wont fill to capacity and if you TILT the bike--the fuel sloshes and uncovers the jet----Basically like a plugged fuel cap---the reason they put hoses on them and stuff them in the frame is so they are away from the dust and flying debris environment your carb is subjected too

I guess i misunderstood what you said ealier. when i asked if they were for the oil injection and you replied " Exactly...correct." But i have had mine blocked off. I should leave them open? The oil injection is the one on the side on the base?

[Unclediezel]

yes---The two black fittings stay open --
You must cap the brass fitting on the side to prevent an air leak

I know this is a really old thread, but the rules say to post in an all-ready made thread, not a new one. So...

I was just wondering if anyone could go a little bit more in depth with what to do in order to run premix. I have attached pictures of my own, and have a couple questions.
1. Where are the 2 small black fittings on my carb?

2. What exactly is the small box type thing that the fuel goes through after the fuel tap, and why do 2 lines come from that? (The regular fuel line, then a black one which looks like it goes right into the piston)

3. I've read this thread many times, but can someone PLEASE tell me everything that needs to be disconnected, plugged, etc?

Thanks a lot :D :D :D

Wow blast from the past, been so long, i cant remember, Trace the 2 lines off the oil pump, plug em up where they go to, pretty much.

I'm not sure about the 2 black fittings but the "box" thing is the fuel pump and the black hose supplies the suction / pressure to operate the pump. The other line is the fuel line to the carb.

Is that ALL I have to do? Cause I really don't want to mess anything up.


And thanks freewheel3 about the fuel pump.

[scooterroo]

the yellow hose is your crankcase breather hose, do not block that off. the two black lines are the oil lines. cut em off, silicone them or plug them somehow, plug the oil feed line to the carb, and mix your gas, alot better then them junk oiljection setups.!!

[pimpallic]

Ok great thanks. But the yellow line is just the fuel line, not the breather hose. The breather hose is black on mine, and as discribed earlier, it starts under the jug fin.

[pimpallic]

Where does the oil even go into the carb on mine???

[pimpallic]

Is there even a line that goes to the carb, cause I don't see one???

I'm bumping this old ass thread.

I cant find a straight answer on what lines to plug up.

from my understanding the 2 black fittings on either side of the carb are breathers.(leave open)

The nipple on the throat of the carb is for oil injection (Block off)

The ones I'm not sure about are:

1. The hose coming out right beside the reed cage on the cylinder head (I think that's oil injection so I blocked it off)

2. There are 2 hoses coming out of the bottom end of the engine right close together on the left side (I think they are for the oil pump so I blocked them both off)

3. Finally there is (or was, I accidentally broke off the nipple today) a line coming off of a little triangle plastic cover right beside the clutch cover. (since I broke the nipple off I just plugged it with a screw) Hopefully I don't need it and can leave it plugged up.

Can anyone help? There are pictures a couple posts above to see what I am talking about. Thanks.

Hi there I have a Yamaha trip moto 125 frame with a 175 smacked in it. Does anybody know how to rehook the oil pump system up?

Do you have a manual for either trike?

[Tri-moto175]

No i t didn't come with manuals

[Tri-moto175]

Still looking for pics of how the system for the oil used to be hooked up and where each line went to thank you .

Me too .

I have a Yamaha dealer near me in Blackstock Ontario so I'm going there tomorrow to see if I can get a diagram cuz the manual I have doesn't show me anything on it

Remember to prime oil lines & bleed before running

[Tri-moto175]

Thanks man I went to the dealer and forgot to mention about the oil lines schamadic we got talking about air filter systems and totally forgot I have a headlight bulb on order and got some stickers. Does anyone know of the air filter guide? I'm missing mine :( if anyone knows somebody who has one they don't need I'd be interested

[Zoila]

i know someone who has had the filter guide remade- they are stronger using a 3d printer & they are selling them

[MTMinge]

Any diagrams available?
