Thank you so much.
This is my first 4 cycle sled. What is a normal RPM?
Can I go WOT? Probably has a rev governor or electric timing retarding program?
What kind of mileage on a tank of fuel?
Maintenance? Change the oil etc?
Sorry for the not responding sooner. I kind of forgot about this thread and got busy with the holidays.
Normal RPM at WOT is 10,500rpm
You can surely go WOT. When I'm climbing it's usually right at the bars. The rev limiter kicks in at 11,000rpm and you'll hear it poppin. I've only blown 1 belt holding it WOT and that was probably a 1/2 mile pull in a stubble field with 10in of snow.
Mileage is right around 10mpg when you are playing and riding hard. That's usually what I get in the mountains. 120-150 miles per tank. Which is a good day of riding and I almost always have 2.5gal of fuel strapped on the back.
Maintenance- Front bulkhead bushings and A-arm/spindle mount bushings. I usually can tell when they wear because they will get sloppy. Make sure the A-arm to spindle mounts bolt stay tight, have had a couple come a bit loose and then the bolts end up bent. Usually every other year or so I think about doing these bushings.
Hyfax, ski carbides, susp mount bushings, just normal stuff. Steering bushings, those you can also tell because you will have play in your steering. Exhaust donuts, those are right behind the short flex pipes off the motor underneath the gas tank (dont't worry there is a heat shield and all that in between) if you start having backfiring issues those probably need replaced. I did my 07 and my 08 around 3000 miles along with spark plugs.
Changing oil, I personally do an oil change every fall before I ride and then and oil filter & oil every other year.
Gas and go really, I do all maintenance myself so with a little guidance, some time, metric tools, they aren't that bad to work on. Just takes some time getting to things like oil filter, battery, front A-arm to bulkhead mounts.
Clutches are pretty simple too. Then your chaincase oil/chain tension as well. Just normal snowmobile stuff.
Oh and the headlight mounts are known to break. Both of mine on my 08 are broke and 1 was broke on the 07 I had. Simple piece of bent aluminum riveted in place and thread tapped works just fine.
