RAVE Maintenance
There is very little that wears in this system and there are no adjustments to be periodically checked. The only possible maintenance required would be cleaning of carbon deposits from the guillotine slide. Cleaning intervals would depend upon the user's riding style and the quality of the oil used. Even when using Ski-Doo injection oil, it is suggested that there be an annual cleaning of the valve. If a customer uses a lower quality, high ash oil, more frequent cleaning may be required.
No special solvents or cleaners are used when cleaning the valve.
