First 150 miles my impressions are pretty much what I noted on my initial impressions BUT : after removing the ugly smog canister the fuel tank started leaking around the edges where main fuel line enters the tank to the fuel pump. All the lines were either plugged or routed properly. Tank pressurization? The canister was put back on and no more leaking. Hydraulic clutch oil leak behind hydraulic cylinder near the countershaft; will take back to dealer for warranty repair. The bike handles GREAT although the fueling at idle is rough which makes opening the throttle in slow speed corners a little difficult but I'm sure that will get better as the bike breakes in. No stalls. I'll keep posting my impressions as the mileage builds up but in the meantime any suggestions on the canister removal?
Try removing the canister but leaving the line(s) from the fuel tank to vent to atmosphere using a one way fuel tank valve/vent. If you previously plugged these lines, it could have caused pressure buildup in the tank as fuel expands, causing the leak.
I plugged the line to the cylinder and extended the vent line that exits from the front left side of the fuel tank and routed it along the right frame rail under the engine.

Careful with this. When you are on the side stand and fill your tank, the gas will flow right out the left side top vent onto the ground. There is a slight delay, then it seems to go on forever. Embarrasing really. The hose needs to route up higher than the tank or a decent check valve has to be inserted, or never top off your tank.
That's no different than what any other bike of mine has done from the factory. That is, until they started bolting on those ridiculous charcoal canisters.
Gas Cap By eliminating the stock gas cap and using this one I am able to fill my tank to the brim.The tank vent gets plugged and all vent tubes removed,now I can squeeze another quart of gas in without leaking a drop.I drilled out the inside of the vent on the gas cap so it's no longer a one way valve and there is never any pressure build up.It works great!
??? Am I missing summat? I´ve filled mine to the brim and we´ve been experiencing the hottest heat wave for over 100 years. Not lost a drop and certainly don´t think that it´s been getting chicken wings .... PS What I would like is a somewhat better insulation on the header under my left knee.
I've had the same problem on my SM630 twice now on very hot days. If I pop the gas cap, lots of pressure is released, and the leak from around the fuel pump stops immediately. The canister was removed long ago. The vent line runs down the frame and is not pinched. Any suggestions? I would purchase the gas cap that Husky666 is using if I knew where to buy one...
Is there still a valve in the vent line. I think it's a good idea to take it off especially during the summer.
Mine used to get 40 mi/gal (6 liters to go 100 km) for the first 1000 kms but after I added the leo and JD unit my numbers are more in line with yours. but that is only over one tank so not much data.
I looked at it again more closely. What I thought was the vent tube must not be. For some reason the dealer just blocked off the vent hole in the tank with a bolt when they removed the canister. Thankfully, I still had the original piece that screws in and allows a tube to be attached. All better now.
Unless he's talking about the drain over the fuel pump... That is just to drain water and excess gas from around the fuel cap (in that pocket). My original tank came with that plugged and the second one had a hose to drain the overflow/rain.
