I took a ride today with Specro GL6 in the tranny. Impressive. Down shifting not as noisy but up shifting is effortless. I was impressed with that precision click as you shift. Finding neutral was also better. I would definately use Spectro again. I also used Bel Ray 10-50 in the engine. Even though there were no metal shavings with the Quaker State I will continue to use the Bel Ray as it has better viscosity at colder tempertures. The Primary also got replaced with Bel Ray Primary oil. I found the Bel Ray was more fluid than the Harley stuff and also noticed that clutch operation was alot smoother.
