Greetings. After a period of abstinence I find myself once more in possession of a motorcycle, a cbr600rr this time. I think it's great, but I have a slight niggling problem with the gear shift - it's not all that slick and requires a very definite press to upshift cleanly, though down is less of a problem. Any ideas what this might be, and easy things to check to rectify it? Cheers
