So...B... What do the flip-flops save you over the riding bootsIts got to be huge!
Hi. I have done the same with my handle bar set up. On my Zx11 with the 1300cc kit I removed the balancer shaft. I had to cut down a freeze plug to fill the hole in the cases also had to drill and tape the oil passage. The rotating assembly was balanced. There was less going up in RPM but more coming down between 5500 to 4000 RPM. And c10 the fastest bagger at Loring is 194 MPH.First sorry its taken so long to answer your questions . From what I have researched ( credit XS1100 yamaha forum ) adding or taking away weight never removes vibration it just moves where it is felt in the rev range . A few examples my ZRX drag bike was very smooth with engine crank shaft balancer , but was terrible once removed . The ZX14 uses TWO crank shaft balancers were they Hayabusa uses 1 . The ZX is butter smooth where the Bird starts to give a mild vibration at 4700 rpms on up . ( still smother than most bikes ) Adding heavy bar ends or filling bars with silicone just move it a few hundred RPMS . I tried the heavy bar ends , and there was no noticeable change over the Rizoma end caps . Keep in mind I just did Three Iron butt runs in 8 days , and vibration was never a issue even cruising 100 plus mph at 5500 to 6200 RPMS . My next trick is to try adjusting the crank shaft balancer while my body work is off . Step one MARK shaft , and ARM before making any adjustment to return to original if a improvement is not found in the adjustment range . The factory adjust it pretty close , but they don't ride it afterwards , and the gear teeth wear in so a minor adjustment can help in vibration . It is adjusted by sound while engine is running . I'll make a video soon on the process .
Things to remember Jeff my bird has handle bars that are hollow , and a diffrent top clamp that is over 4 pounds lighter than a stock bird with its solid clip on bars .
Also if you like research Harmonics and vibration you will find some fun stuff . a Simple worn bearing can cause some peaks in vibration
Considering on gen 2 you need suzukis tool to shut off the ISC valve to do a TB sync, and no dealer will touch my bird ever it will likely never be looked at. The Fjr / R6 / and several other throttle body / fuel injection bikes I have done TB sync to have never been far off enough to see a difference Un like all the carbureted bikes I have done.
Gen 1 you can do that as no ISC valve on them.

I cant risk this one due to touring with luggage / racks / gear . Also when we get to our detestation we park wifes bike , and she ride into town on back of the bird for dinner . Shes good for 600 mile days , but at the end she just wants to relax rolling to dinner .
I have the big Shori @310 cca its is 3.1 pounds When I replace it ill go lighter .
hes going to build me a arm when i'm ready at a very good price. No tank or under bracing 0 to 2" with no over hang like the 0 to 4" . I imagine that would be a 8 to 9 pound arm 
I guess one would need the yosh idle adjustment kit then ?
Carb sticks ? I was referring to the idle adjustment cable like on the gen 1 and other bikes . I know yosh made something for the Gen 2
I'm glad for you buddy, Greg is the man!!I have the big Shori @310 cca its is 3.1 pounds When I replace it ill go lighter .
Talked to Greg Hickman today Fernando
