Well.. after the test ride(s)... it is safe to say that the stock jets are not gonna cut the mustard.
InsuredDisaster: the surge tank, the air filters, the hoses and vacuum diaphram that are attached to the heads and such are removed during a shave. Unless you actually like removing/disassembling carbs, leave it alone. As far as the shave actually 'helping' things, I don't know I'd say that - the carbs were gunked up before the shave and that was making it harder to start. More Seafoam may have cleaned them out... who knows? You'd need tools, lots of time, possibly a helper, a place to leave things disassembled... and patience.
On the bright side, now I'll get to pull the carbs out again which should be much easier now and re-jet/shim etc. Just isn't rich enough at higher rpms.
The sound? Normal at low rpm, LOUD at higher. Not sure who besides the rider can hear it, but there's no sound baffle between the carbs and the world.
