Tragic motorcyclist William Dunlop died in an accident after his bicycle spilled oil on his rear wheel at high speed.
The 32-year-old top runner was killed in an accident at Skerries Co Dublin on July 7th.
A source said, "One theory explored is that William had just crossed a lump on the course, his motorcycle hit the bottom and it ripped off some of the sump."
Open sump poured oil on the roadway – his rear wheel pbaded over this web and he lost control
