John McGuinness was left to rue more misfortune for the second successive year at the Classic TT after retiring from the lead of the 500cc race on Saturday.
The Morecambe rider had set an unofficial lap record of 112.031mph on Friday on Roger Winfield's Paton to mark himself out as the man to beat and made a flying start, opening a lead of eight seconds over Ian Lougher at Glen Helen.
However, his race came to a premature end at Ginger Hall as a result of a front-end issue.
“I'm massively disappointed to have retired so soon in the race as everything was looking so good,” said McGuinness, who was dogged by an electrical problem on his classic racing debut at the event last August.
“Practice week had gone well and having not had the best of years, I put my heart and soul into getting a result in this race and, ideally a win. The bike was faultless during practice week and the 112mph lap on Friday evening felt really good, so I was quietly confident going into the race.
“I was pleased to be starting first on the road and I took full advantage of the clear track in front of me. I knew Ryan [Farquhar[ had a bigger tank so my tactic was to push really hard to try and make sure I had a bit of an advantage coming into the fuel stop,” he added.
“Everything was flowing nicely and to have an 11-second lead half way round the lap [at Ballaugh Bridge] shows what kind of pace I was on and it would definitely have been a strong opening lap.
“Just after Ballaugh though, I knew something was wrong and had no option other than to cruise along the Sulby Straight and pull in at Ginger Hall for a pint,” he explained.
“I've never had anything like that happen before and to be forced out of the race by a 10p bolt working its way loose is a hard one to take. I'm disappointed for Roger and the whole team as they've worked really hard and it's not cheap to get these bikes built and prepared.
“It's no-one's fault though and there's nothing anyone could have done to prevent it; it's literally just one of those things.”
Ian Lougher won the race on the Flitwick Motorcycles Paton from Dan Cooper and Bruce Anstey.
