Beginning with no bodywork, 27-year old tires and a single operating brake (rear), I rebuilt the clutch master and slave cylinders and added a hydraulic line which gave me an operating clutch. Next, I bungeed the instrument pod in place as its mounts are broken. I wanted to add lighting fore and aft but decided it wasn't worth the effort for a 1-mile test ride. I would need a little fuel, of course, so, lacking a better alternative, I zip-tied my fuel bottle to the handlebars with just enough gas to feed the carbs without leaking from the lid. Finally, I needed somewhere to sit so I slid the seat into place, which actually worked okay considering the rear latch wasn't mounted. And off I went to a nearby straight stretch of country road long enough to allow up- and downshifting through all six gears.
Success! My contraption worked long enough to determine that the old clutch functions well and the shifting feels fine. Back on the lift to strip it all off the bike — it's not actually ready for those components at this point in time. This test gives me the confidence to move forward with the project.
