Ratio

The stock injection pump is variable mix. At idle it is 100:1 then at about half throttle is is 40:1. For premix I would go 40:1

I run 32:1 . Run as much oil as you can till the plug fouls out then back off a little.

Are you switching to premix and removing the pump? 40:1 is generally recommended, but 32:1 is easier to mix.

If you are pulling off the pump and going premix you need to mod the case to get oil to the PTO bearing.

Well my buddy who i bought this sled from already did all of that! i have never owned a sled that i had to premix the fuel! but i do appreciate all the help and good answers!im thinking ill try 30-1 most likely

I wouldn't go heavier than 32:1, that is more than enough. It's nice because you can mix 4 oz to a gallon and get the right ratio.

Go buy a ratio rite, you can get them from any dirt bike store. They have the ratio marked out on the size, makes it stupid easy.

I was manually running the pump to fill the lines this morning after rebuilding the engine and it seems like carbs get alot more oil than the crank lines. And the Pto side line might be getting more oil than the mag
side. Does this seem right?

 

[sled_guy]

Carbs should get more than bearing lines... you use a lot more oil through the gas mix than dribbling in to the bearings.

I don't think there is a difference between mag and pto though. But if the PTO gets more oil that wouldn't be a bad thing.
