MAINTENANCE
Good maintenance is essential for safe, economical and trouble-free operation. Here you will find a
maintenance schedule for your engine.
Routine inspection procedures are very simple by using basic tools.
Some service tasks that are more difficult or need special tools must be performed by Vortex technicians or
qualified mechanics.
Timing schedule periods are only indicative. Extreme carburation set ups highly modify timing schedule periods.
