This morning started out with low clouds... but part way down the road the sky cleared spectacularly, at which point I switched on the video. "Easy", the bike I am on, is in much better running condition since the last time out. There was partial blockage of the primary carb's valve seat screen/filter... so the fuel flow was limited for higher rpms and speeds. In the process of sorting out the problem, I managed to break the tip off the mixture screw... and was frustrated with its symptoms before finding out, the second time the carbs came off. Anyway, 4-20 was a beautiful day and we would later be in Petaluma for the Eggs and Butter Day Parade.
