Correct.

 

ok thank you

 

wait wait wait. why did you premix? do you still or are you still running the oil injection?

 

yeah please dont listen to brp, wait and get some good intell before you make up your mind

 

i bought it last spring and the guy who i bought it from said he doesnt like useing oil injection because it can fail, so that is why the oil light was on he said he always pre-mixed it. so i decided i might as well to. i just wanted to make sure i wasnt supposed to put oil in the tank also. i kind of thought no but last time i went with my gut i did stuff wrong so im not taking any chances.

 

If you premix the oil into the gas in the gas tank you DO NOT need to put any oil in the oil tank.

 

thank you for the info im just wondering, why did slamdry say this?

yeah please dont listen to brp, wait and get some good intell before you make up your mind

 

its because BRP hasn't made too many friends here, hes not ALWAYS wrong though, well, on second thought i take that back

 

Well what im wondering is if your gona premix, why is the tank even still on there? Im not sure so ill ask, Is that even safe to keep the oil injection set up on the engine while premixing all the time and running NO oil in the tank?

 

look if the oil injection is still on the sled and is functional you are bes tto use it. It will mix the fuel and oil as needed as opposed to the same mixture all the time. (IE if the sled is running harder the oil pump can add more oil were as if you are running pre-mix thats all you get)

No
If you intend to run only Pre Mix, you need to disconnect and plug the injection system port's
If you leave the injection system intact, you will draw Air into the engine'=Lean=Burn down.= NOT GOOD.

I was actually thinking that. Thats messed up, it would suck air into your engine where its not supposed to be. And im guessing this guy would have done this, left the tank completely empty and burned the motor down.

BRP is Not Always Wrong, but
He's Rarely Correct!
He's young and full of himself, and his info could lead you to Worse problem's than you already have.

This is a Vey Good answer.

 

I read the exact opposite of that. That the oil pumps arent oils adding the right amount at the right times, like the throttle is halfway open and almost all the way on the pump. But i dono, people are always gona believe whatever they want haha.. Im fine with both types i guess, wasnt a fan of the premix when i got the sled but ive been using it, Well only a couple times so far ive ridden it but still. Either way as long as its getting oil its good to go haha..

I`m guessing you have just bought a 87 SRV Yamaha?
If this is correct, the previous owner is PARTLY correct.
These engines have been known to have the gear on the crankshaft that
drives the oil pump, come loose. Also they have a rubber coated expansion plug that likes to fall out of the pump. Been there, done that. Some of the early Phazers do it too. Had thet happen to me as well.

As one of the guys stated, plug the oil lines if you do not use the injection system. They are right about drawing in air. May not be a problem most of the time, but when it gets REAL cold out and more fuel is needed, this open line will NOT be your friend.

 

Just a personal belief I have.
I would rather run Rich and Over oiled, and replace a few Fouled plugs, than have to Have to Rebuild a Burnt down Engine.

P.S. I have'nt fouled a plug in the past 4 yr's.!

Im pretty sure that 50:1 is 50:1, at any engine speed. Premix supplies more oil the same time that it supplies more gas cause its already mixed in with the gas.

Eliminating the oil injection removes one mode of failure (mechanical) while introducing another(human). If this sled is prone to oil injection failure, then I would remove it personally. If you do, be sure to plug any holes or ports and be careful not to mix it too lean.

im not farmiliar with the yami but the mechanical on the older po's are driven off the throttle lever, so as you yank it harder it ads more oil for proper lubrication. i guess its personal opinion weather or not to use it, i know i love to pull up to a pump and jsut fill up without having to worry about how much oil to add to the tank for the amount of fuel i put in. but thats my opinion.

 

I think thats actually the other thing i heard, its a constant supply of the same oil ratio, i dono for sure. But ya it is just personal preference. I have yet to get real riding in and be filling that damn 440 tank up all the time since it sucks up a bit of gas, mixing the oil is gona get old i bet, then its time to throw that injection set up on it haha

 

i wont lie, i push my sled harder then most people would dream of and have done it for 4 years now and have yet to have a issue. 3500+miles and i spin it at 9K+ and its still stock internals, holds between 120-125psi per cyl so i cant complain

Right, as you add more fuel (throttle) the pump keeps you at a constant 50:1 fuelil ratio. With premix, your at 50:1 weather at idle or 9000 rpm, cause the fuel is always 50:1.
Im def a big fan of oil injection too. I hated mixing at the pump in my older sleds. I was always paranoid I screwed up the mixture. But in 87srvsnow's case, I think I would be more scared of the injection failing just cause of the history of his particular model.

 

I wouldnt recommend running straight 50:1. I know some people do, but I definitely wouldn't. Whenever I pre-mix, I keep it between 32:1 and 40:1

i agree he jsut needs to decide on one or the other so he doesnt bring more issues. Witht he previous owner pre-mixing and leaving the oil pump on that would be why it has such low compression now. But we are still waiting for him to get a screw in comp tester to determine the actuall compresion of it.

do you not quit, you have no idea what you are talking about AGAIN!!!!!!!!

Run 50:1. Nearly all sleds that ever came with oil injection were designed to run 50:1.

I wouldn't recomend you give ANYONE else advice on what to do with their sleds. It's like your just trying to fuck people up by giving them the shittiest advice you could dream up. I seriously hope your not as retarded as you make yourself seem.



P.S. I HATE you, and stop giving people advice, moron.
