Guy Martin will miss the inaugural Classic TT races on the Isle of🌠 Man after failing👍 to meet the signing-on deadline for the event on Wednesday.

The road racing superstar arrived on the Isle of Man yesterday but has been excluded from competing on the M𒅌ountain Course, where the opening event of the 2013 festival takes place with the 500cc race tomorrow.

Martin had been due to ride fo꧃r Tea💧m Molnar Manx Norton in the 500cc race.

"There's be൲en a lot of trouble with the protoꦑtype Manx Norton. It wouldn't run properly until tonight (Thursday)," he said.

"I arrived over this morning (Thursday) and the organisers wouldn't let me practice - so there was no option other than to𒁃 head back home. Bugger!"

Martin took the Ulster Grand Prix by storm last weekend at Dundrod, winning thr💮ee races for the Tyco Suzuki team, including both Superbike🦩 events.
