ive posted on here a few times about my sv. i got it MOT'd on a friday and they said it ran perfect, it rode awful with stock exhaust but when i put my skorpion can on with no baffle it ran sweet as for the whole weekend. on the following tuesday i rode it and it started backfiring constantly. after a few mins i tried to start it again but it constinued to backfire. now the bike is cold it wont start, it will turn over and sound like it wants to go but wont. this happened before but i thought it was other issues so i replaced, plugs, HT leads, HT caps, ignition coils and i cleaned the carbs twice and it seemed to work after being stored over the winter on an optimiser. could it be the rectifier or battery not giving a strong enough spark or no spark?

Any advice would help.

thanks,

Sam
