On my way down to silverstone my vee k7 suddenly developed a engine fault,basically the engine management /oil light came on with F1 fault.the engine started missing and would not rev without spluttering and farting.I stopped and killed the engine and restarted it ,the light went out but still sounds really sick.up to top gear it makes clunking noises and misses like hell.if it was a four cylinder bike I would describe it like it has dropped a cyclinder but I am guessing it is an air intake problem or intermittent plug or fuel injection system,but am just guessing.can anyone please advise me what I can check myself without going to the expense of taking it to a dealer.
