Frequently Asked Questions

Q: Does this kit include everything needed to seal the exhaust pipe to the cylinder?
A: Yes, this Vertex kit is a comprehensive package that includes the essential O-rings, springs, and washers required to properly seal the exhaust pipe junction on your CR125R.

Q: How often should these exhaust gaskets be replaced?
A: You should inspect your exhaust seals every time you perform a top-end rebuild or remove the exhaust pipe. If you see signs of dross, oily buildup, or carbon staining around the exhaust port flange, it is definitely time to replace them.

Expert Pro-Tip: When installing new O-rings on your 2-stroke exhaust flange, put a tiny dab of high-temp silicone grease on the O-ring. This prevents the O-ring from binding or tearing while you slide the pipe into the cylinder, and creates a superior secondary barrier against leaks.
