Well today started out well, like any other day. Since my family was going to have dinner at my sister's small apartment in Denton, we had all the food prepared and ready to go. My mom left in the cage to haul the food but my Dad and I were not ready to leave yet. Since the weather was nice, we decided to ride up there. He rode his 79F and I rode the 79SF. I must say that I am falling in love with this bike. It still isn't my favorite though. Well to get to the point, this bike has had some engine trouble long ago that I was never able to recreate in order to isolate the problem. Well today on the 35 mile trip to Denton, it decided to show up. In neutral, the engine revs fine and sounds awesome. When I get up to around 70-80mph, I begin to loose power. I seems as though some cylinders are cutting out when I open up the throttle. I don't know how to tell which ones are cutting out because it only happens at high speed. Does anyone have any ideas about how to tackle this problem? If I could recreate the problem in my garage, it would be an easy fix. Well, in order to make it to Denton, I had to keep it up around 90mph. When I got to there everything was great untill I got back on to go home. I noticed that my right side cover was missing and the rubber gromet that holds it in place was destroyed. 
Now on the way home, the engine ran as though nothing had happened. The only good thing that happened to the bike was that lagging spedo finnaly decided to work properly. It wouldn't zero for about 3 min if you were going even 45mph.
I can not describe was is happening to the engine well enough because I have no idea what is happening to it. It seems as though just one cylinder is cutting our but I don't know how to really tell. If it is was a fuel problem, how could it just come and go like that? Being an intermittant and rarely occuring problem, that leads me to believe it is somesort of ignition/ wiring problem. I was thinking maby the pickup coil wires were bad, but wouldn't that problem only happen when THe throttle was opened or closed rapidly changine the manifold pressure? Could it possibly be the TCI getting hot and cutting out one coil? Or, could one coil be cutting out? On these types of days, I really feal like a meathead because I didn't notice the side cover flying off Although I am still laughing from when first saw my new status lol
