How do you remove a restriction on a Yamaha PW80?
Pull the exhaust manifold down slightly to expose the round gasket resting in the recess of the exhaust manifold flange. Remove the gasket and the small restriction washer underneath it. Place the gasket back into the exhaust manifold’s flange recess. Mate the exhaust manifold back up to the engine and reinstall the two retaining bolts.
How big should the exhaust manifold be on a Yamaha PW80?
If you have a torque wrench available, tighten the exhaust manifold bolts to 13.5 foot-pounds to avoid any possibility of stripping the bolt or cylinder head threads. In the spring of 2008, Blaze Johnson decided to share his expertise through writing.
Why do I need a restrictor hole in my exhaust?
The purpose of the restrictor hole is to prevent the cold bypass water as it enters the exhaust elbow, from back-flowing down and into the manifolds. If the restrictor hole is positioned incorrectly the cold bypass water will flow downward into the manifold and prevent the manifold temperatures from heating up enough to prevent condensation.
Can a marine exhaust manifold be installed incorrectly?
Marine Exhaust – KEEL COOLING: Keel Cooling is often installed incorrectly and can cause manifolds to crack internally from excessive heat. Do not install exhaust manifolds into keel cooled systems that rely solely on the water circulation pumps with a small diameter pipe for its circulation.

Is it possible to mod a PW80 bike?
Yes the works shock raises the bike, but im not sure how much. Im sure if you look hard enough you can find some forks that will fit. I’ve seen many people talk about switching the forks but never seen it done yet. Not too many people mod pdubs we are a rare breed. Most people will tell you to sell it and buy a real 80.
