1. Remove seat bucket.
2. Undo the bolts that hold the factory-fit air cleaner on to the transmission housing.
3. Follow the rigid pipe from the air cleaner to the rear of the carb. Undo the pipe clip and remove the pipe from the carb.
4. There is a small pipe going from a little valve at the front of the exhaust to the flexible pipe on the intake to the air cleaner. Disconnect this at the air cleaner end and stow it somewhere out of the way.
5. Remove the air cleaner intake hose from its mounting; you can now completely remove the factory-fit air cleaner and bin it.
6. Put the free-flow filter onto the carb; sometimes the throttle cable gets in the way in which case you may need to make a short intermediate tube as detailed elsewhere in the forum.
7. That's it... But you now probably want to adjust a few things as the extra air means the engine will be running very lean:
a) The needle valve inside the top of the carburettor.
b) The air/fuel mixture screw on the carburettor.
c) The main jet inside the carburettor. You probably want a bigger (about #90) one; you can get them from scooter-assassins.com (accepting paypal again, as of 24 Sep 06).
Advice for a), b) and c) is available elsewhere on the forum, with a bit of digging.
By the way: does anyone know much about the little pipe running back from the exhaust to the air cleaner intake?
I gather it's to put a bit of exhaust gas back into the engine to reduce nitrogen oxide emissions, but when it's disconnected will this make the scooter emissions illegal?
If it is left disconnected, is there any difference in engine power between blocking it off and leaving it open at the end?
And if it is connected back into a freeflow filter, does this recirculation of exhaust gases significantly affect engine power?
