Whibley said: "A quick check revealed all was good there. Then I tried changing gears but still the bike wouldn't drive. I checked the gear lever and all was good there too. I finally found that something had hit the clutch cable and twisted it. Once I straightened it out, the free play returned.
"While I was messing with the bike, four or five guys went by and, after another quick stop to adjust my twisted clamps, I was back in the race.
"I began making my way forward, retaking the positions I gave up while working on the bike and by late in the second lap I was moving back into the lead.
"The rest of the race was pretty uneventful, putting in safe and consistent laps, eventually taking the win."
