The bike is a '99 CBR600f4 with 7100 miles...I have had the bike for about a year now...when I bought it, it had 5900 on it....anyway, when I take off in first gear and get on it and shift into second, once in awhile it makes a mild clunking noise when shifting.....I've tried it quite a few times...sometimes it makes it and other times it doesn't....Could it possible be that when I shift fast the clutch doesn't fully engage? Anyone experience this?...The local Honda shop isn't my place of choice to take it to...so if I have to take it to be looked at, it's 100 miles one way....Just want to make sure there is a problem, before I make the trip....
