i premixed my oil and i just wanted to be sure that i should not put oil in the tank. correct?
Right, as you add more fuel (throttle) the pump keeps you at a constant 50:1 fuelslamdry said: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.Luke said: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.slamdry said: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)
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.
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.Luke said:Right, as you add more fuel (throttle) the pump keeps you at a constant 50:1 fuelslamdry said: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.Luke said:Im pretty sure that 50:1 is 50:1, at any engine speed.

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.
do you not quit, you have no idea what you are talking about AGAIN!!!!!!!!BRP-4-LIFE said: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
Run 50:1. Nearly all sleds that ever came with oil injection were designed to run 50:1.BRP-4-LIFE said: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

thats also plus the oil injectionstormrider62033 said: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,
