Guys, i have about 18,500 miles. My bike is mainly a weekend rider with a few track days in between. Basically, I do my oil change every 3,500 miles and just changed my chain, sprockets, and air filter. When did you guys do your valves and did they find anything major wrong?? I know that job will cost me $$ so just wanna see what i'm in for.
