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

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)
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.
Right, as you add more fuel (throttle) the pump keeps you at a constant 50:1 fuel:eek:il 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.

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.

ok well since XCR-nuts said my sled is known for oil injection failure, im probibly goin to get rid of the oil injection. this isnt complicated to do is it? i just un plug it, then disconnect the hose right. whatdo i plug the hole where the hose was with?
 
do you have any pictures of the oil pump assembly?? that would make it a bit easier to determin a block off method.

no i dont sorry. but i was about to take the tank off and i noticed there is still oil in the tank. does this mean i have been running extra oil?

i just stopped by at a sled shop and he told me to mark were the oil in the tank is, and run some pre mix through it and if it goes down that i should just use the oil injection. so that is what i am goin to do. thank you for any info anyways
 
im no pro but i would just put a shut off valve in the lina and never have to screw with it again
 
If you want to see if its working, do exactly what that sled shop said...put some oil in and mark your tank. Then run pre-mix through it. If the oil line drops, the Oil injection is working. I eliminated oil injection on my Rotax/RMK. the Rotax was different than your set up i think. I had to keep an oil flow and loop the two inlets to the engine because these lube the main bearing of the crank.

If you want to block your oil injection off, just leave about 2" of oil line on each port. Then shove a bolt in each that is bigger than the I.D of the oil line, then clamp it for good measure. Anyone Disagree?
 
i run oil injection and haven't had a problem yet. i would probably premix but then i cant just put in gas, check the oil and go
 
say what you want ,but if you read the manuals for any sled ,,if its oil injected ,you're also suppose to premix the gas below -0,

thats also plus the oil injection
 
I recently bought a 06 fusion dragon 600 ho. it has been modded fairly decently, and the oil injection system is off of the sled. What ratio should i be mixing? rite now i am doing a 32:1, mixing 2.5 gallons at a time at the gas station. not a big deal to me but some people are like "that sucks blah blah blah". What holes should i be looking for? i know the basic operation of the system and i just wanna make sure my sled is up to par! last thing i wanna do is burn her up! look at my gallery to see some of the pics for the motor mods! PLEASE HELP!!

ALSO what temp do sleds run at? i was on the trial last weekend and it got up to 150 degrees but i was babying it and was trying to get back home on fumes otherwise i watched it and it was usually running about 130-135, is that warm cool or rite in the middle?
 
thats safe but i was always told 40-1 is alright
 
Any one running 50:1 will burn up there sled if they do any real riding if when rpms go up so does oil demand and if u hold rpms high 50 1 is to lean and u will be rebuilding it very soon and getting new jugs when ur rings snap off and scar the walls and fuck ur piston up . 32.1 if u like to bag it maybe a little richer if u hold it at 9 for long pulls . 50:1 ur all fucking cooked . Look up the specs it's not running 50.1 at 7 to 9000 rpm on any sled ever any were . Why would some one say that 50.1 is a good idea . this its not a chainsaw wtf . And so many benefits to premix better top end performance security that ur engine wont burn down. fuck that oiler and tank let it ride if the pump is already fucked its pluging the hole that the air can supposedly come through . and it cant deliver oil so how the fuck would it deliver or draw air . Make yourself work for no reason leave a little oil in the bottom of the tank if that's a concern and if it can pull air in those tiny ports u got broken oil lines between the pump and the engine . Facts .
