Running Hot, really hot!

My thoughts were that its either something wrong with the cooling system or a very lean condition. I check out the cooling and the water pump is working fine as far as I can tell. Then I move on to a possible lean mixture. Two friends have the same bike and the same jetting and have no problems, so I rule out jetting for now. I find that my fuel hose from tank to carb has a small hole and that if I squeeze it gas squirts out. Replaced the hose and rode for about 45min with no overheating. Could that have caused the problem? Could I have caused any damage if I rode an extra 10 minutes back to the truck after noticing the problem?
The bike is a 2001 426, bought last week with 90 miles on it, air box/ exhaust open, stock jetting, riding at 6000ft. Changed the oil before riding, and after the ride.

I'm going to say that was definitely your problem. The engine would have been sucking tiny air bubbles through that hole and as those entered the carb, it would have the intermittent power loss situation you described, and as a result of the extra air in the fuel/air mixture, you would have been really lean as well. I think it would have probably been lean enough to cause the overheating you speak of too.
As for did you damage it, only time will tell. My first car used to overheat alot, and every time I did it when it cooled back down the head would warp slightly. I know this because about 4-6 weeks later it would blow the head gasket. Man, i got really proficient at changing that too...
Hopefully you'll be alright.
