Hey guys. I am looking for some help. I have a 94 V Max 600 that I bought last fall and ran it twice last season. Problem I am having is oil consumption. 110 miles and the low oil light comes on @ 140 miles I added 2.5 quarts to get to the full mark. I installed a new cable just after I bought it ( just due to age). Set the cable to 29 mm as per spec in the shop manual. I did notice a little "wetness" around the seal of the pump but nothing major. (removed pump to install new cable) I have read on here that when these pumps go bad they go to FULL RICH setting, is this correct? Any thoughts to correct this?
Thanks Mike

I just went through the same thing with a 94 and 95 sled I bought.
If nothing else is broken on your sled, then the consensus is that the manual spec is too "rich" on oil, and the cable adjuster needs to be reset so that the index mark is moved back about 1/8" with throttle wide open.
When you close the throtle, the stop on the oil-pump indexer will engage before taking all of the 1/8" you just adjusted into the line. But at anything past 1/4 throttle (approx), your new setting will reduce oil consumption.
The goal is approx 1 qt per tank of fuel, or 50:1 if you convert gallons to oz.
I made this adjustment in two stages, just to be certain that oil consumption didn't drop too much because of other unknown factors. Obviously, oil starvation to ratios well in excess of 50:1 would be very bad.

I never really measured them. After reading the tech page info and other similar posts, and after using 1 qt every 40 miles, I knew they were unchanged from the too-rich factory setting. My objective was to adjust until the indexer mark was about 1/8" shy of where it used to be at wide open.
drop the clutch access panel, lay a flashlight down there pointing at the oil pump indexer. open throttle all the way with right hand, screw down adjuster with left hand until you see the index mark back off 1/8" from being aligned with the stationary mark on the pump. Tighten the lock nut. That's it.
I still recommend doing it in two steps.
Do a 1/16" tweak first, top off the oil res, ride 40 miles, top off the oil res and see how much you used. If it takes 1 qt, nothing changed. If it takes 1/2 qt, you're perfect. If it takes a 1/4 qt, you're way oil-lean and frying your motor.
What kind of mileage are you getting? Mine were getting 7 mpg at 5000' elevation, but I discovered they were jetted for 10K. WOW!
These sleds have poor fuel economy. The general consensus is to jet down 1 size per 2000' elevation above sea level. My '94 came with factory 151.3s with the needle clip in the middle position. The local dealer and board members here recommended 145 with the clip moved up one notch to #2 position. I now get 10mpg cruising and maybe 8.5mpg driving crazy. Unless you live above 9000', don't change from the stock pilot jet size. You can accomplish what you need just by adjusting the exterior "fuel" screw. This screw regulates air through the pilot loop. Back it out to allow more air (leaner). Mine were out 1.125 truns (factory setting). I backed them out to 2 turns out, and actually got a hot-motor light while my wife was putting up a hill. So I reset to 1.5 turns out, and they seem fine.

Is this the preferred method of checking oil cable? Based on the service manual I'm not sure how to check the cable...do you just pull the cable side towards the oil pump until its taught and measure there? I noticed mine was about 1 1/4 inches and changed it to 1 1/8 inches, but I don't know if I'm doing it correctly..any help is appreciated, thanks....
