Running Rich

Hey, I am new to the sport and picked up my first sled this year. It is a 98 Ski doo Touring LE. It is in great shape from what I can tell. However, it does seam to smoke and run rich. Is there a way to adjust the amount of oil that is injected? I do know that the guy i bought it from replaced the oil injection because there where air bubbles in the lines, or so I am told. On my jet ski's I jut remove the pump and install a block off. Is there a block off readily avalible for these? Is there any reason why I wouldn't want to be premix on a sled? Thanks in advance. JB

It should nearly stop smoking after the engine is warm. (5 min)
Have you done plug chops to see if the jetting is correct?
Most a set up a little rich from the factory as a precaution.

Excuse my ignorance, assuming you mean reading the plugs? They are a bit on the wet side. They are still the stock carbs so I would imagine jeting is fine. It definetly smokes a little more than I am used to as far as 2strokes go.

To get back to my original question. Is there a way to adjust the oil injection? Is there block off kits to buy for these like there are for jet ski's?

The injector pump cable should be adjustable, but if your not familiar the sled or the process, I wouldn't attempt it. I had a smoke problem with my 89 Eltigre and just changing to a synthetic oil eliminated 95% of the smoke without messing with the factory settings.

If you follow the cable to the pump (below the carbs), you will see and adjuster on the casing. There are marks on the lever and pump housing that should line up at idle and WOT. If at WOT, the mark on the lever is past the one on the pump, it is too rich.
The lever should not even begin to open until the carbs are almost 1/4 throttle.

this quoat is exactly the info ive been looking for my 95 ski doo formula stx 583 rave. is this the same as far as the oil injection goes? the lever shouldnt even begin to move untill about 1/4 throttle? look forward to hearing back as i cant seem to get an answer on this one. my oil lever end was moving 1/4" before the slides began to move and i was getting rediculous dark smoke when pinning the throttle
