Hi can anyone help me, i have recently purchased a Gilera vx 125 2008 new shape, it has been running fine for about 2 weeks, then i decided to get a scopioni exhaust which works fine, all of a sudden one morning the bike did not start tothe point it killed the battery, so i replaced the battery to discover it had the same problem of not starting, so now i have also replaced the coil aswel as spark plug, but for some reason it still does not wont to spark, i have been advised that i may be able to reset the bike with the master key?? can this be done? please if anyone as come across this please let me know how it was rectified, other then that the bike was a good ride, i travel about 16miles every day into central london and bike works a treat when it did work.
