Hi guys, just bought a cup bike and done two road Tests. Both times the engine cut out when dropping down the gears. I dropped the clutch while still rolling at 20mph but it wouldn't fire. It started as soon as I stopped and selected neutral. Any ideas ? I also get loads of screen vibration can it be cured. ? I need it sorted for the U.K. Mallory 1000 bikes festival in July. Any help appreciated. Thanks.
