I have an 03 and it has 23,000 miles on it and has always been cold natured ( especially in cold weather). I have found that if i leave the choke/enrichment pulled out a little for the first 3 or so miles, it runs great. These bikes are mostly all cold natured. The next time it starts bogging, reach down with your left hand and pull the choke out until it stops bogging. Then push it back in after a few miles.
There is nothing WRONG with your bike, it is just a combination of factory lean condition and restrictive intake/exhaust.
Yes, you can make it better, IF you want to open up the intake, add an aftermarket exhaust, and rejet the carb. Too much money, when you can just pull the choke out a little. Just my 2c
Plus, i would run some seafoam thru the fuel system to finish cleaning it out.
