Frequently Asked Questions

Q: Why is it important to replace exhaust springs and O-rings?
A: Exhaust components lose tension and elasticity over time due to intense heat cycles. Replacing them during a service ensures a perfect seal, which is critical for maintaining proper exhaust scavenging and peak engine power.

Q: Does this kit include everything needed for the exhaust flange?
A: Yes, this Vertex kit is designed as a comprehensive 2-stroke exhaust sealing solution containing the O-rings, springs, and washers required for your specific model.

Expert Pro-Tip: When installing a new exhaust gasket, ensure all mating surfaces on both the cylinder and the exhaust pipe are completely clean of old gasket material and carbon buildup. A small amount of high-temp silicone or copper-based anti-seize on the hardware can make future maintenance much easier.
