I had to google oil vapor catch can, to figure out what it is and does..lol
It seems semi important to crankcase breathing and overall life of the engine. But that was just my take on the article I read. How important is it? Do I even need to have it hooked up? |

During normal operation, pressure builds in the bottom end of an engine, and it must be allowed to vent (or it will find a way out). Most dirt bikes simply have a vent hose that goes from the top of the transmission (just under the carb) to the ground, routed between the engine and swingarm. The problem with that design is that dust will be drawn in to the engine. A catch can allows the oil vapour that is forced out to be collected in a reservoir. It is also usually connected to the air box, and that can turn an air filter black due to oil vapour contact. The simplest way is to use the dirt bike method, but stick a filter on the hose to prevent dust from entering the engine.

I'm betting it's a charcoal cannister to collect fuel vapors. Trace the final hose and see where it leads.

Remove the single bolt for your gas tank and dis-connect the fuel line then pull off your tank and inspect where this line is going to, my personal Xf does not have a separate vent line connected under the tank anywhere just a vented gas cap. Remove the charcoal canister, air pump and all the extra hoses as they are not needed and are not going to damage or affect the engine if they are not in place.

If 09FX200Q's cap is not vented, he'll need to retain the hose and at least put a filter on it. He might be able to get a vented cap through Taobao.

Yeah I took the tank loose and it is an air hose. I removed the charcoal filter and capped everything but the air hose to the tank. Added some extra hose back to the breather hose and it's running great. Thanks to everyone!

Is your tank venting with that hose now?
