FWIW, ST1100 stock rear shocks usually turn into pogo sticks around 50,000 miles.

Weight savings if I keep the bike. Call me crazy, but I think I can drop 50lbs from the curb weight. Won't be easy, won't be cheap, I tend to do this a lot with a lot of the bikes I've owned. Some call it a sickness, some call it an obsession... my therapist calls it a "my catharsis."
A 50 lb. diet (I could technically cheat part of it by removing the bags and replacing the lead acid battery with a lithium one) and about a gallon of gas within would take about 100lbs. off of the curb weight of 700 lbs. and not far from that of an FJ1200. If I can do this, I'll take the ST to a trackday for sh!ts and giggles. C Group, of course, where speed will likely be limited by ground clearance anyways.

Thank you, that would explain a few things, lol.
So your going to vent the gas tank fumes into open air ? That is crazy.Weight savings if I keep the bike. Call me crazy, but I think I can drop 50lbs from the curb weight.

I won't do any differently than I do on my performance bikes on or off road. If you are referring to the environment, I've always lived my life well above average cleanly/greenly, well before it became a political issue. I'll live with the guilt
When gas get hot it expands. The gas tank is mounted behind the engine it does get hot, and builds pressure unlike a many other bikes.I won't do any differently than I do on my performance bikes on or off road.

"cleanly/greenly,"? A vapor canister, also called a charcoal canister, is a component in a car's emissions control system that absorbs fuel vapors from the gas tank, preventing them from escaping into the atmosphere and instead allowing them to be burned in the engine as fuel, thereby reducing harmful emissions.
Good point. Just a cautionary tale......
Several times over the last few years I have had auto repairs delayed because of crap like this. Latest was a suspension rebuild on our car. The mechanic called me up told me he couldn't find but one complete strut assembly...the bushings were missing from the other kits. He ended up striking out several times and personally visited his local distributor and they checked some of his stock. Most of the kits had been returned by other shop's than Roberts with the complaint 'will not fit customer's vehicle'. This guy is a neighbor and has been doing all the auto repairs I can't or won't for over 30 years now....so I trust his discovery. ALL the opened/returned kits were missing parts. Nice little scam by several repair shops in the area (Dallas/Ft Worth). The distributor now has his folk inventory returns before returning any $$$.
Just be cautious and do an inventory if the package has been opened.

Thank you for the lesson.
My first generation 49-state VFR and second generation FZR (carb,d like the ST) do not have 'vapor canisters', nor do several of my earlier model fuel-injected bikes. IIRC, nor did my first generation V-Max, Hurricanes, dirt bikes, Vespa, Monster... I could pointlessly go on and on, if you like. Should I add a charcoal canister to them to mitigate fuel vaporization? I typically run all open lines into a catch can located in a relatively cool area of the bike.
To clarify: I recycle everything (carry trash with me from vacation/business travel, and bring home trash from the office)/dispose properly, compost, walk/run/bicycle distances less than a few miles, solar, Army shower, do not drink plastic bottled water, collect rain water, etc etc etc. I am not a hippie, environmentalist, or a climate nazi. I simply do my best to not waste or pollute. But with my motorcycles, if I run leaded race fuel, remove PAIR.AIS during racebike prep, or vent/drain to a catch can, I don't lose sleep at night. I don't think of it as an offset... I'm simply a Gasshole, lol. YMMV. Thank you for your concern, though.

Please give it a rest. I'm trying to be nice. You strike me as someone who wouldn't have the cajones to say that to me in person. Just sayin'... good luck, and ride safe."I simply do my best to not waste or pollute. But"

FYI
all EC spec ST1100's have the fuel tank tray drain, the carb overflow and the fuel tank cap breather tube routed down, ending aside the main stand axle...
only the case vent is routed back into the air filter housing to "reburn" any blow-by...
so what does the canister do? What
Yes, so what is the canister for and why is there a purge control ?
A charcoal canister absorbs and stores gas fumes until it's purged and burnt when the engine is next run.
My point was to see if you understand how these things work because there is no performance increase by eliminating canisters or pair valves . Those things only weigh a few pounds . IMO
Exactly
Agreed. My Nighthawk 750's performance improved when I lost weight.
