Evap?
 

I replaced my air cleaner today on my '02 F4i and I noticed that the vacuum hose from the bottom of the gas tank going to the evap canister was not connected. Also the overflow hose right next to this one seems to be M.I.A. My question is, would hooking this back up effect my bike in anyway? or could i just remove the evap canister?

You should be able to hook it back up without any problems. I thought your bike would have thrown a code for it not being hooked up, but maybe that doesnt trigger a code. Personally, I dont think they do a whole lot in the way of polution control, but they are required on california specific models, so I would just leave it on there, it doesn't hurt performance or anything.

As for your overflow vent tube. You really should find out where it is. If its kinked, it will restrict air into the tank and can limit the amount of fuel that able to be pulled from the tank. It could even starve the fuel pump and the bike will die out.

the other issue with not knowing where the vent tube is comes in the event that you purge some gas out of the line, and the line is not directed away from your rear tire. You go into a corner hard, the tank purges some gas out and onto your rear tire. sudden loss of traction. This scenerio will more than likely never happen, but its a good idea to get that tube pointed away from the rear tire.

Doh! wait a minute.. Does that bike use the evap tube as the vent?

I think the tank vents through the evap line. It wouldnt make a lot of sense to have an evap line, then a vent line, it would defeat the purpose of having the evap line..

It actually has 2 lines coming off the bottom of the tank. the smaller one goes to the evap and the larger i guess is the fuel vent line ... but i don't know where it goes from after it comes from the tank.

There should be a loop down by your left foot peg that the hose just simply slips into. it just hangs down and the loop keeps it in place.

Sweet found the other hose ... i guess they guy before me had zip tied it to the frame near the left foot peg. I am going to hook it up next time i have the tank off. thanks
