Fuel issues cost 23-time winner lap time on 600cc machine
John McGuinness says it was frustrating not to get two laps in on his Supersport machine after encountering a fuel problem.
The 23-time winner had hoped to lap the course twice on his 600cc bike, but was forced to stop of Ballaugh to make adjustments.
Last night's issue, along with red flags during sessions earlier in the week, mean McGuinness hasn't had much time on the Supersport ahead of today's final practice.
He says the fueling issue cost him valuable time:
