Now I know this won't apply to many people here but just in case you are still running the stock exhaust and air filter do not hesitate to upgrade it. I fitted our hosts british made exhaust system, fitted a cone filter and rejetted the carb. I have just completed a 1hr run back from watching the olympic road race in surrey to my home. I could not believe the difference it made, the bike runs so much better and the extra grunt up hills is well worth it. I kept mine stock for 5 years (350 iron barrel) - i wish i had changed it sooner, if it is left stock you are not getting the best out of these wonderful bikes.
