Holding up great runs like a champ

As far as the idle screw, it shouldn't be shaved down; it should be just the stock screw with spring all oem parts, no Chinese parts or carburetor they won't ever run right. The oil mod is a personal preference. I am already mixing gas, so for me, it made it easier to mix one for all quads. Plus, you never worry about the injection getting clogging.

Purchased oem from the dealer

Kill pull cord on the back of the quad should have a cord attached unless someone bypassed it

@@quadjunkie007 thank you, that will cause the pull cord to spin freely?

No the pull cord will just kill the Ignition spark. If your pool cord is spinning freely something has come apart and not assembly where it attaches into the firewheel you've missed something putting it back together

@@quadjunkie007 I was in a hurry and trying it out before I left, forgot to put break on lol after I remembered I didn’t do that, it worked fine. But after it ran a few minutes (4-5minutes) maybe after it heated up it kept stalling. Any idea as to why? My guess is gotta adjust carb. Got late and stopped messing with it.

I removed the oil mixing tank and pump. I mix my own because I am making it for 3 different 2 strokes. Now I make 32:1 for the 250r lt80 and the 50.

@@quadjunkie007 that makes sense. So if I leave the oil tank and pump on there, I just put normal gas in it correct? I just bought this 2004 lta50 last week and I’m putting new carb on it so haven’t fully looked into it.

Actually the main jet it came with ended up being fine. I removed the restriction screw in front of the main jet and then it worked fine. The pilot stayed stock

@@quadjunkie007 oh ok, that was probably the screw behind the main jet screw in your video correct?

Pretty much I wasn't going to split the case to do it wasn't needed

@@quadjunkie007 no problems so far?

@@POOL_EXCAVATIONS nope hade the quad for about 8 years

@@quadjunkie007 does it run any better?

I don't have it in a pdf but I'm sure you can find it on Google

Yes I do believe so

32:1 same as my trx250R

Yes it is a 2 stroke engine

My air filter came in a kit when I purchased the full mod kit for the quad. I don't have the info readily available at the moment. I'll see what I can do on finding it again.

I use benol for everything 2t I own.

There's a drain plug bolt in the bottom of one side of the cases. Remove that bolt drain oil and re fill from the top hole.😁

What type of oil did u use?

@@blu76blazer I used my honda 80 90 I believe it was

Your welcome I'm glad I could help.

Need a video of this or pictures, want to try it

No I used the stock manifold but you need to use a heat gun to heat it up and you can stretch it over the 38mm carb

Nope 32:1 ratio same as my 250R

I run 32 to 1 ratio same as my trx250r so I only have to mix one fuel

What size jet did you change the lt50 in order to run 32:1?

I don't quite remember what the trick was o did it awhile ago. Needle nose pliers. It looks like it's just sitting in there from what I can tell.

@@quadjunkie007 Negative. It won't come out.

I think I just lifted straight up with some small needle nose pliers. I remember it slipping down a couple of times and starting over. It's a tight fit. I see there is a notch in the side of the black plastic but I don't think it has to align up with anything. I can look tomorrow closer at it. But very small tip needle nose pliers and pull up. Try turning the motor over and rotating it around. Make sure it's in the off position though.

@@quadjunkie007 The pump is dead. It hasn't worked in months. Which is why I want to remove it.

@horsepower house your part of the big dogs views program. Nice job.

Nope I didn't find anything either so I broke down and spent the dough. You can buy the K&N air filter separately but you won't have the adapter to mount it.

@@quadjunkie007 Ridiculousssss

@@quadjunkie007 What about a different type of carburetor? Surely there is SOMETHING else that can fit that intake manifold and has some sort of air filter mount like many other bikes do.

@@HorsepowerHouse If you have a Machine lath You could turn one out of a piece of aluminum. The problem is there's not much demand for this small of a quad so most of the big manufacturers don't manufacture anything and the one that does has no competition. Welcome to motorsports none of it makes sense but we all do it for fun

@@quadjunkie007 ( if I had a device like that, I would not be here trying to find such a part...)

This is for the oil injection on mixing the gas with the oil and sending it to the cylinder to get burnt and lubricate the cylinder walls with the gas. The bottom end has transmission fluid in it that sloshes around when the crank spins while running. There is a fill hole on the side of the case for the transmission fluid and a drain plug on the bottom. Hope this helps.

I’m wondering that myself, the transmission fluid is for the transmission not the bottom end/main crank shaft bearing. On regular 2 strokes, a small part of the oil air mix goes below the piston and lubes the bottom end when running. Since this motor isn’t made to allow that small seep,(assuming since it is plumbed to have that injection oil go there and to lube the cylinder rings) I feel that by blocking the oil injection off will eventually lock up your main crank.

@@christiantillman84 Fuel goes into the crankcase first and up through the transfer ports to the top of the cylinder. When you use fuel/oil mix it will lubricate the bottom end of crankcase first.

Main jet 80 Needle clip 3 down from the top

I don't remember the pilot jet I will have to check a d see if I can find the record on It

thank you much appreciated.. I’m going to purchase the kit now.

Jets themselves shouldn't cost 200 bucks. You can buy jets for like 5 bucks each from your dealer it's a stock OEM carb. Buy the jets from the dealership or parts store. I wouldn't pay 200 for jets. Now if you are buying the kit including the air filter and jets and air filter adapter different story. I was told the wouldn't sell just the jet kit though you had to buy the entire exhaust pipe kit including the carburetor kit all at once.

Actually jets are around 100 after looking more into it. Going to purchase the pipe and kn filter +adaptor and get a jet kit seperate on amazon.

OCD

What size jets are you running in yours right now I just got a 90 lt50 and I want to eliminate the oil injection system to run 40:1 ?

@@_.southern_cali_rc_5966 90 on the main jet stock I think on the pilot. Although I think I could go up a size or so on the pilot idles fine once started but must give it gas in order to start it.

I don't ride it just my kids do and it does just fine pre mixed.

@@quadjunkie007 I beat the piss out of mine and nothing happens lol

Steve, I don't know if you'll see this but I have a dumb question. Why would keeping the oil injection tank and everything allow you, a heavier guy, to ride around all day? How does it help?

@@jeffglauser4108 Because me being a heavier guy puts a ton more stress on the little engine which means more heat and the more oil you can get the longer the engine is going to last because it’ll have a lot less heat with more oil so less friction

@@steve5912 and premix wouldn't provide as much oil as the injector?

It's a 2 stroke I believe in to 2002

CT racing Google it I pulled it right up. LT-A50 50 it's a package deal you have to buy the set up. They won't sell just the pipe.

ua-cam.com/video/OnwjlzpKjAE/v-deo.html

Sounds like it could be time for a rebuild or it's just oil build up and a oil Saturated exhaust system. I bought the package from CT racing it came with the pipe filter piston and aluminum round thing that attaches to your carburetor for the K&N air filter to fit. You also have to send a head in to have it milled it's an expensive package but there's quite a bit of difference between that and stock. Plus you need to remove any of the restrict or plates that were put in by the factory if it hasn't been done already in the muffler and on the intake.

I am pre mixing my gas and oil together and no longer need the oil injection system. This way I can control how much oil is being used. The oil injection system run extremely rich and if they ever get clogged up you'll burn up the motor this solves that issue. I have 3 quads it allows me to mix one set of gas and use it across all 3.

Nope it runs like a champ.

Yes there is the hose coming from the oil tank reservoir going into the pump to push it into the carburetor and get sucked into the cylinder. I blocked the intake off going into the pump and removed the reservoir.

That's the oil injection hose. There was a hose coming from the oil tank to the injector pump that's what I removed.

Thanks for the quick response Robert. The hose that i am referring to is the very small one that is connected to the silver looking cylinder and on your video the hose seems to lead to the pull start. At .49 on your video you almost zoom in on it before you head back to the table.

At .49 on video its on the top left side of the shot.

That is the crank case breather tube connected to that silver cylinder.

Yes the I had to re jet it and go up pretty big on the main jet.

What jets did you end up using and where did you get them from? Having a hard time finding bigger jets

@@quadjunkie007 Yeah what jets did you go with

Are you planning on de-restrict that little beast :)?

Yes I changed the jets out on the carb.

@@coronadoegsi All the factory restrictions have already been removed along with re jetting aftermarket racing pipe K&N filter and piston and milled the head.
