Variable Exhaust System (VES)
Maintenance of the Variable Exhaust System (VES) is limited to a periodic inspection and cleaning of system components. Bring the machine to your dealer to have the VES disassembled, inspected, and cleaned at the intervals outlined in the maintenance charts.
To ensure maximum performance and minimize required maintenance, follow the oil recommendations. The use of other lubricants may cause improper function of the valve mechanism and increase the frequency of required cleaning due to excessive build-up of carbon deposits.
