Sudden loss of power under acceleration

Thanks for all the great advice. I think I found the problem. Check out the crud caked onto and around the fuel filter (pictured). Was pretty easy job to pull out, clean up and replace. I did the plugs and air filter as well. He's running a lot better now, needless to say. Be warned anyone who buys a bike with claims of it being well/recently serviced. Check everything to keep safe and get home 

Bloody hell, surprised it ran at all, might be an idea to have another look after a couple of tanks of fuel to see if there is any more in there

Glad its sorted Mate. Did you have a good look around in tank? Has to be a reason why so gunked. Id be running a couple of tanks of good fuel cleaner or even a tank of E10, will suck any water through and burn in motor. E10 is fill and ride until empty, not to sit around. I do it every year or so.
