Biker carried on riding despite leaking machine
The Clerk of the Course has appealed for fans to pull off the road if there's a problem with their motorbike.
Today's practice and race schedule had to be delayed by 25 minutes following an oil leak on the Mountain Road.
The marshals reported the rider initially pulled in at Windy Corner before carrying on, resulting in a sweeper being needed to clean the road before the action could get underway.
Gary Thompson says it's disappointing to lose time:
