That is your oil injection system. Unless you are premixing (I use 32 to 1 synthetic), you better have that hooked up or you'll fry that baby.

If oil is coming out, it's working (NICE), so may as well hook up and run straight fuel.

[junkrider]

btw- I'm jealous. I gave one away after my divorce and regretted it ever since.

[james9r9r]

I,ve been running it without and that hose has been soaking the whole thing in oil...

SO where do I hook it up to and isnt that crankcase oil coming from the hose???

and my motor shouldnt be fried yet should it cause ive ran it for a while???

[ceaserthethird]

What is that thing .... LOL

[james9r9r]

LOL Well I almost just fried my dam morot cause the oil tube wasnt connected.

LOL Well I almost just fried my dam morot cause the oil tube wasnt connected.

That’s why a lot of people disconnect the auto lube and run premix. As long as it works, put on new lines (clear so you can see the oil) and use clamps. My brother had a YT125 for a short time, I only had a chance to run it around the yard for a few minutes before he sold it, that was long enough for it to dump me off the back though! Careful with those machines, they can be a handful.

It looks like it is in nice shape, so may of the YT's are beat. Was it an ebay find? It looks familiar. Oh, the front forks are on backwards, it should be a trailing axle instead of leading axle. Maybe it would handle better the way it is now though, those things need weight up front.

[james9r9r]

no i got it 20 miles away and are the forks on backwards????????????????

I notice some bolts are missing and someone must have dumped it because the handle bars are bent

[junkrider]

james-


I was correct. The oil injection hose does definitely go to the fitting you had circled in the picture. If you do decide to skip injection and run premix, then you absolutely must cap that tube, else you will run lean and melt the piston.

Here's info from the archive from 3ww.com:

-mike. 100% sure that it is absolutely the oil injection tube.

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
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?
