when I had to take mod 1&2 due to a balls up by DVLA I hired a bike from the cbt school to take the test as I could not use my 250. In the car park of the test centre for mod 1 the examiner took one look at the bike and said "you cannot use this bike" when I asked why it turned out it was not taxed. left bike there, called school and told them they would have to collect it then had to arrange a lift home. Second attempt bike was FOC due to first time, and this time it was a wet day. Started well on test until it came to the swerve test. the bike was a Suzuki 125 with all the power of a 3 legged horse so had to rag it out of the corner to reach the required speed and cocked it up completely through the cones. went round again to do the emergency stop, though it was pointless as I had already failed on the swerve, but thought what the heck, lets just get it over with. went through the speed trap at 35mph, hit the brakes and pulled in the clutch at the same time! result, I locked the rear wheel and down I went. I put my right hand out to break my fall, and hurt my shoulder. I rode the bike home with a very sore shoulder, but just wanted to be done with the bike. That night I was in a lot of pain and discomfort so went to A&E for check-up. They diagnosed a pulled muscle and put me on physio. After 6 weeks of this there was no improvement and I started getting really bad pins & needles, so went to docs for examination. I got booked in for a MRI scan with a injection of some kind of radioactive solution to show up the joint as it is covered with a tough membrane that need seeing through. Turns out I had torn most of the muscle off the shoulder so got booked in for surgery. I had keyhole surgery to insert rawlplugs into the bone in 5 places and the muscle was then attached to the rawlplugs with stitches. None of this put me off riding, as soon as I was fit enough I bought a 1988 Honda cb125 twin, that has 16BHP and took the mod 1&2 on that, and this time I passed both. The pulling in the clutch was a rookie mistake, which I put down to the frustration of ballsing up the swerve test
