More Roar 'n Soar

Waiting for start flag

Not a knocked over cone, but the outer limit of the course

Clearing the far end gate

Winding out a bit.

Took the wirewheels in to be re-balanced. They were over 6 years old and starting to show 'green' deterioration. I ended up buying a set of Michelin 205-60x15 tires. Smaller than the old Dunlop 215-70x15 tires they replaced.
