Our friends at Black Magic Racing reminded us to remind you to go out and start up your sled, like right now. Seriously. Where is your sled and how did you put it away at the end of the season? Did you take the gas out of the carbs?... Read more
What is considered “normal” oil consumption for a 1000cc Yamaha RX 4-stroke engine? Anything up to one quart per 1,000 miles, according to Yamaha.

Owners of Polaris models fitted with plastic airbox fittings (that the carb vent lines are attached to) want to verify these fittings are not broken. If they are broken or cracked, the carb vent lines and float bowls will not “see” the proper airbox pressure, resulting in a rich... Read more
A good number of Summit 1000 (and some Mach Z 1000s) that we spotted in the field last season had removed the plastic deflector that shields the intake filter material on the left side of the machine. Most riders commented on how this area would allow snow to build-up... Read more
If you own or ride a 2004 Firecat (or Sabercat) you might want to pay close attention. There is an oil line under the engine that is known to chafe and can actually break, and we all know what happens when a 2-stroke doesn’t get any oil. If you... Read more
