The original 05 Mach Z had an oil pump setting of 16.5 mm and was plagued with plug fouling problems. The oil pump setting was changed later that year and prior to the 06 sleds being released. The 06 sleds had a Warranty Bulletin because some sleds were delivered from the factory with the wrong settings. A Warranty Bulletin was created to resolve that issue. In early 2006, BRP issued another Bulletin that included the proper procedure for setting oil pumps on all sleds along with a tool designed to eliminate variances in settings due to improper methods used by dealer techs. The 3 procedures are listed below with the final procedure shown last.
The oil pump setting is important but is actually just a recommended setting to attain a given fuel to oil ratio. When BRP was answering dooTalk member questions, they stated that the fuel to oil ratio on the 1000 SDI should be 45:1. Now, how do you measure your actual fuel to oil ratio and what does it mean. The easiest way to understand the ratio is to look at it in terms of quarts or liters. I will use quarts as it is how I measure mine in the field. The ratio is for every 45 quarts (11 1/4 gallons) of fuel that you use 1 quart of oil should be consumed.
Here is how I ended up checking my fuel to oil ratio. With my oil tank near the top, I removed a little over 2 quarts of oil. I then let the tank sit for an hour and drew a line on outside of tank even with the oil level. I added exactly 1 quart of oil and then drew another line on the outside of tank at that oil level. I then added an additional quart of oil and marked that level on the tank also. You will now have 3 lines on the outside of your oil tank to monitor oil usage. I had already filled the fuel tank to a level you can see in the filler neck. Now run your sled until you use roughly 10 gallons of fuel. I use 5 gallon cans to fill my tank and monitor the fuel usage. After using 10 gallons of fuel, check to see if oil level is approaching the middle mark or 1 quart consumed. If you have consumed significantly more oil than expected, then your oil ratio is less than 45:1 or you are getting more oil than needed. The reverse is also true. If you use let's say half a quart of oil, your fuel to oil ratio is around 80:1 and you should definitely shorten your existing cable setting before proceeding with the second half of the test. If the usage is close after 10 gallons, then run until you reach the bottom mark on your oil tank. You should have used 22 1/2 gallons of fuel if you are at 45:1 fuel to oil ratio. Shortening the cable, increases oil usage and lengthening cable decreases oil usage.
The first procedure is from the 05 RT Shop Manual.
