the only other hose I had to deal with on my 2013 FI R* when I removed the AIS
, was during the removal of the charcoal canister. It has tubes that go from the roll over valves from the fuel tank to the canister, then from there to the back of the air filter box.
I simply removed the hoses off the canister, then I removed the hose from the air filter box, and put the rubber plug over the tube, that the kit came with. I routed the hose from the roll over valve down the frame so that it vents the tank down under the bike.
If you aren't using an AIS removal kit from barons for our bikes, and you aren't removing or do not have the charcoal canister on the bike (it is on california models only)then there isn't a vacuum hose on the FI bikes that I know of.
Also, I would go ahead and just get the barons kit with the two flanged covers for the place the AIS tubes bolt to the jugs.
I removed the AIS on my bike, and it stopped all of the popping and backfiring. the kit is only about 25$
getting to the place you have to bolt the covers over the hole on the rear jug is kind of a pain in the butt, I had to loosen up the atmospheric sensor module and move it out of the way a bit to be able to get to that spot.
