    I am seriously considering removing the cannister from my 09 Stelvio to make some room for aux wiring for horns and lights. I have most all the tupperware off already, and since I am here, I thought why not. My question is after the cannister removal, would I have to retune the bike, such as TPS settings etc. I have read all the posts i could about the procedure but am unclear that additional tuning is necessary. My bike was running flawlessly before i put it up for winter, so would removing the canister change the tune?

    Two other questions. The Instructions for the 2012 cannister removal; are they the same as for the 2009 ? Also, the vent line that runs up the left hand side of the fuel tank; where does it terminate? The right rubber hose has a clamp and an obvious nipple to reconnect with on the plastic that attaches to the top of the fuel tank. For the life of me I can't find a nipple/connector for the left rubber hose, and it doesn't even look like it was ever attached to anything. It has no deformity to the end of the hose and as i said there is not clamp. What am i missing??

    The body panels are different, vapor recovery system is the same.

    The parts book show the the vapor and spill tubes configuration without the charcoal can. The dump tube is up front, you may want to relocate it to the rear to discharge behind the trans as shown in the diagram.

    Both hoses connect to the gas cap frame bolted to the tank. One connects to the high inlet for vapor and the second connect to the spill trough.

    Okay, but what I am saying is that the left rubber tube looks like it was never connected at all given that the vent nipple on the gas cap frame is larger than the inside diameter of the left hose, and the left hose shows no indication of ever being attached. )size distortion, clamp, etc.


    Thanks for the reply. I will sort it out as i put it back together this week.

    If that hose is up by the airbox it is probably the transmission vent hose. Leave it disconnected.

    If I remember correctly, the left side one or the cap drainage one is smaller than the tank vent at the fuel pump. Irregardless, just strip out all the vent tubing making sure that you connect between the TBs with a single piece of tubing (keeping it away from the cylinder cause mine was touching and melted), and have them run down just in front of the rear wheel between the frame and engine. Then your good to go. Oh, and the 'tipover' valve? Just something else to clog up. Dump it. :D

    Thanks again for the timely reply Cruisin' Guzzista. Will do. Can't wait to get her back together again since spring is just around the corner. New horns, bright aux LED lights, and a cannister removal! Life is good. :cheer:
