Frequently Asked Questions
Follow the vehicle service manual. Most modern intake/exhaust gaskets are designed to be installed dry. Excess sealant can squeeze into the port and cause leaks or flow restriction.
No. Intake and exhaust gaskets are generally considered single‑use wear items. Reusing them greatly increases the chance of leaks and poor performance.
Common signs include ticking noises near the exhaust flange, sooty deposits around the joint, popping on decel, rough idle, and in some cases poor throttle response or backfiring.
On most motorcycles and ATVs you only need to remove the header or manifold from the head, but access can vary by model. Check your service manual to see which bodywork or components must be removed for access.
A properly sealing gasket restores correct exhaust and intake sealing, which can improve throttle response and reduce popping if your old gasket was leaking, but by itself it does not add power beyond restoring factory performance.
Installation Guide
Difficulty
Medium
Est. Time
30 min
Tools Required
- basic metric socket set
- ratchet and extensions
- torque wrench (inch‑lb or small ft‑lb range)
- scraper or plastic gasket scraper
- shop towels / rags
- brake cleaner or non‑residue solvent
- light abrasive pad or Scotch‑Brite (optional, for surface cleanup)
Pro Tips
- Always check the service manual for the correct torque spec and tightening sequence for intake and exhaust fasteners.
- Dry‑fit the manifold or header first to ensure the gasket aligns properly with ports and bolt holes.
- Use a plastic or brass scraper to avoid gouging the cylinder head or manifold sealing surface.
- Loosen and re‑torque bolts in sequence (usually from center out) after the first heat cycle if the manual recommends it.
- Inspect manifolds and flanges for warping if you see repeated leaks in the same area.
Common Mistakes to Avoid
- Re‑using old intake/exhaust gaskets instead of replacing with new
- Not fully cleaning old gasket material from the sealing surfaces
- Over‑torquing or under‑torquing the manifold/header bolts
- Installing the gasket backwards when it has an orientation
- Using excessive RTV or sealant where a dry gasket is specified
