Nice looking bike. Wish I'd found one with original paint.
Seconded on the clean the caliper. you might as well just order a new seal for it as well, cause they're like, 5 bucks and if the thing leaks you've contaminated your spanking new pads. Brakes on these things aren't crazy good in the first place. Consider upgrading to stainless steel lines.
Don't know on your lack of power issue. Around here, you'd better be able to go 75, eh? From previous discussions, you might want to make sure that your fuel delivery is good (tank vent clear, fuel filter clear and good routing if installed, clean carbs). There's a filter above the float needles that was practically packed full of crap on mine.
And subscribe to the DC area rides thread over in the regions forum. Maybe we'll actually all manage to get together for a run some day.
