Nope, you just the wrong jets. There are a couple of flavors of Keihins and you want to insure you 're getting the CVK jets when you order them. The local Honda shop should have the correct jets for you or you could order them from Bellacorse (I've had good results from there).
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
