Yes you may need to remove the fairings on the front side of bike to access the top of engine where spark plugs are located.

Bill,
What you are describing sounds like an ignition coil breaking down as soon as it come up to temperature. It could also be as simple as a spark plug and most probably is. I tend to disagree with the suggestion you received about the contact points (if your motorcycle actually has them). Generally points will make a mess out of starting and if they are failing wouldn't wait 20 minutes to let you know. I'm going to say spark plug(s) (change 'em both) then possibly a coil OR the high tension lead is shorting against the block or some part of the frame. Now I can't say names or someone will get upset but a German made motorcycle doesn't generally work to well with spark plugs made in America. Been in the Recreational business for a lot of years and if there is one spark plug that just works it's found in every Honda MC and of course is made in Japan. Hope you picked up on were i was trying to lead you ;-). Cheers have a great day, hum you riding your motorcycle and I'm up to my bum in snow and getting another foot of the stuff :-(
