Took the 500 for its MOT today, but never reached the test centre. Bike started first time, and ticked over nicely while I finished kitting up and opened the garage. Stopped at a red light, everything still OK, but as soon as I moved off the bike stuttered like it lacked fuel, but got me to the next set of lights though still rough lights changed and as I pulled off the bike lost all engine power and began backfiring then stopped altogether. Phoned and cancelled the MOT, then called the RAC. Chap turns up in his van, I explain what's happened and his reply threw me. Because the bike had no MOT or Tax he could only arrange recovery to a garage, not my home. After a brief conversation between us he offered to help Push the bike back home, (fair play mate) which is exact what we did.
Anyway, stripped tank off to get at plugs and gave the cylinders a compression test. I have zero compression from the right hand cylinder, and I am stumped. Why has it lost compression now, yet has ran lovely whilst stationery and up and down the alley to check the gears
