I got my 01 zx6r jetted a local dealership a while back and was never happy with it. I put a full race exhaust on, which I guess they probably only see in less than ten percent of cases and the tech was not willing to listen to my problems afterwards. The bike was very difficult to ride. It bogged badly off every start - I needed to blip the throttle just to get it moving. Power was down quite a bit on the bottom and mid-range, with only a slight improvement on the top end. Anyways, after wasting $350 at the dealership just for jetting ( and nothing else ), I felt I had little to lose by giving it a go myself. In the process, I found many excellent resources. For about 24 cents in shims and less than 2 hours labour - which I could have easily done in half the time. Why the experienced mechanics at the dealership charge 2.5 to 3.5 hours for the same thing, I don't know. Maybe the same reason they charge $80 for an oil change.
To start with, I went to the Factory Pro website ( http://www.factorypro.com/tech/carbt...m_engines.html ) and found that I had a rich condition at the bottom end and most likely a lean condition in the midrange. From looking a the spark plugs, the main jet size looked about right. The first fix was easy .. just turn the air fuel mixture screw in one full turn. The second problem was a little more complex .. shimming the needles a little more. At first I was a little apprehensive about this, but after finding an excellent post in another forum ( http://kawiforums.com/forum/topic.asp?TOPIC_ID=10743 ), I felt much more confident about doing it myself. The post shows a standard jetting fix for a slip-on and should be the same for most bikes. For my fix, I added one 0.5 mm shim to each needle to the 0.5 mm shim that was already added by the dealership. ... What a difference Much happier with the bike now - Smooth starts and pulls much, much harder through the midrange. The only thing I'm pissed about is wasting $350 at the dealership.
Besides this, there are a couple of lessons I learned:
i. Don't let the dealerships use your enthusiasm for your new bike to overcharge you for shoddy work.
ii. Use the resources available to you. There are tons of great info and how-to's on the web. All you have to do is look.
