Hey guys need a little help. I seem to have a small problem when up shifting at times it misses the gear it seems to do it more under no load just taking off normally. When I up shift an I let out on the clutch theirs nothing and I have to hurry and up shift again then its fine. The clutch feels fine so I don't think that is the problem not sure what it could be, I have a 1998 ZX9R with abour 14,000 on it. Oil is changed at about every 2,000mi, and I don't really drive the bike very hard. Any thoughts?
