My 500 feels a lot more sluggish since I've put 2000 miles on it. When I bought it, the owner recently had the carbs cleaned and had it tuned up. I've changed the oil about 1500 ago. But the bike is pretty sluggish off the line...I also can't pop a wheelie anymore, Redlining at like 2 mph then dropping the clutch wont even get it up... Bike has 13000 miles on it.... Any suggestions?

air filter?
another carb cleaning?
tune-up?

pull the spark plugs and try to read them(and replace them, they are cheap). also it wouldnt hurt to change the air filter and fuel filter. you could also sync the carbs(need a vacuum gauge though)

How about a valve adjustment, and what is the chain tension like?
