Installation note: On some applications, the cylinder cooling fins at the base may contact the flywheel. If this occurs, the affected fins must be ground off for clearance. This does not affect cooling performance or cylinder longevity. Use a grinding bit and proceed carefully — any damage from modification is the owner’s responsibility.
Off-road use only. Not intended for use on public roads or land. Not legal for use in California on pollution-controlled vehicles — check local laws before installing. Performance parts are not covered under warranty.
