Thanks for your help
Thanks for your help guys, it did turn out to be the plugs.
It is very difficult to remove and replace them but it can be done using the tool in the kit provided for the bike. One thing I did discover is that you cannot start this bike, or any other I suppose, rev it up then shut it off. This fouls the plugs almost immediately. If you have to start it over the cold season let it run till the fans come on then shut it off if you are not able to ride it for a while. Also dont trust your radiator fans to keep it cool while idling. If you have a portable fan sit it in front while the bikes heats up. Thanks again.
