Tuned engines will be allowed again at the two sidecar races at T.T. 2014.
Organisers have decided to return to "Open Class" regulations after talking to many of the competitors.
For the last two years, crews were not allowed to run tuned engines in their outfits in an effort to bring costs down.
However, after consulting with the teams, operating budgets appear not to have signicantly reduced.
