My plan was to go for a nice ride to the end of Del Puerto Canyon. The weather was nice- a beautiful 89 degree day with blue skies. I got dressed in leathers and headed out to Mines Road in Livermore.
Mines Road up to the Del Valle split was pretty good, as I was following a couple other motorcyclists. After the split, I started heading up the twisty hill. About two miles in, I was hearing weird pinging noises. At first, I wasn't sure what the noise was, but after I looked down, I realized that it was the gravel in the road being kicked up by my tires, bouncing off my exhaust system. There was a LOT of loose gravel in the road. I rode for about another mile, but after almost having the bike slip out from under me on a tight right-hand turn, I decided that the rest of the ride was going to be unenjoyable, so I doubled back.
After I popped out from Mines, I decided to just make the best of the afternoon and to take 84 back to 680, just so I could get in somewhat of a ride. 84 was nice and clear, not much traffic and no road hazards. I got back on 680, heading toward home and jumped on the throttle a little, just to open up the carbs. All good was restored again.
