So, if the LEADER engine runs better without the evap hose connected, who's to say we can't just remove the cannister altogether?

The idea struck me as I was at the San Jose Vespa/San Jose BMW dealer yesterday checking out the Portofino Green LXV (ma-ma!) and saw ALL the BMW bikes had the evap cannister prominently attached way outside the frame and in a very easy-to-access spot. This seems like both an afterhtought for us "Baum-Umarmen der Kalifornier" and a way to let the buyer know that it can be taken off easily; it was almost begging to be removed.

So, I want mine gone off my GT. How do I do it, and what do I need to connect to what?

It's not so much that they run better without the evap system, just that the evap system is easily overwhelmed the first time you overfill your tank. On the GT, simply disconnecting the evap hose at the carb will remedy the problems caused, and allow you to reconnect it later if necessary. You could remove the cannister, but it'll only save you about a pound or two.

The GTS is a bit harder, because the clamps are harder to remove and because it appears to fail in a different manner, allowing vacuum to form in the gas tank. I think there's a valve that gets stuck, independent of the evap cannister, and requires removal of the gas tank vent hose from the valve.

I left my evap canister in there because it was a bigger pain to remove it than it was to just disconnect.

This reminds me of the crappy truck I bought recently where the previous owner removed certain evap components and subsequently made it a nightmare for me to get it smogged. Leave it in there, you never know when the smog nazis will require us to smog these mopeds of ours.

I just cut the hose. Easy to splice back together that way.
