Organisers have changed the running order for this evening's TT practice session.
Solos will go first, 6.20pm-7.50pm, with the riders hoping they'll finally get the chance to take their big bikes out ahead of Saturday morning's opening Superbike race.
At 7.50pm there will be a lap for the seven Lightweight competitors who are only in that class.
Sidecars will then head out from 8pm to 8.50pm.
As usual, the Mountain Road is scheduled to close at 5pm, the rest of the course at 6pm.
