I figure that I am ahead of the game by simply having the single muffler on a standard.
And further ahead with alloy wheels.
Remove center stand? I will admit to removing it from my 1976 CB750F, primarily for looks; but having it on my Triumph and now on the CB1100 makes chain maintenance easy. Also, if I want to fully top off the tank, it gains 0.2 gallon (might not be good on a California bike)...some of my trips are a stretch between fuel stops: Alamo to Tonopah, via the Extraterrestrial Highway, is 161 miles (Warm Springs is a ghost town)...doable if the speed limit is adhered to...but not much margin.
Tools, Seal N Air, foot pump under the seat are a couple pounds, but I am certainly not leaving them home.
Remembering how my Yamaha XT250 behaved in cross winds in the mountains (more than once with gusts over 60 MPH), having s certain amount of mass can be good.
Do I need more acceleration? No. Getting on a freeway, I typically short short shift to second before twisting the throttle...easier to keep the front wheel down.
Stock, plus a Dart Marlin and a small tailbag suits me just fine.
