Reply To: Help identifying mystery pipe!!
Hey.
The metal pipe that is at the rear cylinder or front is for fake emissions.
It steals piston energy & air from airbox to fake readings for emissions. (Euro3 nonsense!)
Not to worry. It is a good thing yours didnt. Early hyos didnt have it.
Here is what you do. Find a fat 10mm hose(thereabouts) .
Cut 1 inch of it. Get 2 metal clamps.
Put a fat bolt in one end or a metal bung/plug.
Shove the blocked hose to the metal pipe thats on engine.
Its best to do this before running it! Cant have pistons suck debris in.
