I shimmed the needles on my 96 6r (23,000 miles) a couple of days ago. Basically the same procedure except for the following differences: there are four separate vaccum valve covers with 4 screws each, the second cover from the right has the choke cable attached to it making removal a bit more challenging, and the shimming was a bit different (no clip or plastic holder, there is a large spring then plastic holder before the needle), I put my washer over the needle and slid it back into the needle holder, before replacing the plastic holder and spring. I drove over a 100 miles yesterday and throttle response was improved midrange between 4000 - 9000 rpm. It did feel a bit sluggish above 10000 in 4th gear + at times. Not sure about this, but will be looking into... the washer shim is free so it may be affecting how the needle returns when letting off the throttle...?? I can not compare performance to a jet kit, only comparison is to the way the bike performed on Monday versus Wednesday. Sorry, I did not take any pics while doing my work.
