Just fired up the 650 with its new engine for the first time and took it for a spin around the block. YEEEEHAAAAW. Runs perfect, shifts perfect, sounds, smells, tastes perfect. Not finished with it yet, few odds and ends to go on, a few more tweeks here and there and then a final deep cleaning and polish. First ride of the season, although short, was great. I can barely type I'm so happy.
