Don't bother with a dyno jet carb kit. What-that will cost approx $70.00 and for what? $12.00 in jets? This like most Kawasakis have a wide range of factory jets and all it takes is a little know how. Most hardware stores have washers approx .020 that are good for shimming the needle and most DLRs will have jets in stock. Bring up the needed 1 or 2 washers thick and increase jetting at least 2 steps over stock. Then get the motor warm, resync the carbs and set your iddle mix. For a couple of hours time and under $20.00 it will be a different machine.

I've tried to, I'd say the benefits are fairly limited. Stage 1 Jet Kit (yes you could do it cheaper by buying the parts), K&N Filter, aftermarket exhaust, no airbox lid (seemed to work better after the jet kit was installed that way).

The cold starting is much better as someone else noted, maybe a bit more mid-range and top end. I wouldn't call it dramatic.

I've owned two. Same probs with cold starting. The bike no like! As far as performance, it makes 95 ponies already. Just twist the throttle harder, i'tll go.

It is ridiculous how dismissive people are about the Concours, especially if they have never ridden one. It's a good bike. Yes it is an old design, but it still works pretty well. What is ridiculous is that people think it is reasonable to pay $20,700 for the same type of bike. (See recent MO sport-touring comparo.)



Check out the Concours Owner Group. They can give you information on the bike based on actual knowledge and experience.

After 20yrs of building a bike that has remained unchanged mechanically why change it now?

Yamaha did the same with the V-max. You don't fix what is not broken. I say leave the motor alone. Upgrade the suspension to suite your riding style.

I own a 19yo BMW K100RS- Mods to the bike include a Supertrapp exhaust (that was there when I bought it), Progressive HD springs w/ 10 weight oil ('cause I'm a lard a$$) and a Works shock. I now own a wonderfully stable $3300 motorcycle that produces about 90 rwhp and the ability to haul a$$ and get 40mpg while doing so.

From and investment standpoint there is no longer any reason to spend huge sums of money in the aftermarket on performance upgrades on bikes. You will never see a return on such an investment in your re-sale value.

Those mods would accomplish two distinct things;



1) That would kill your low and mid range torque.



2) It would ***** off the few cars that you do see on your commute and help to draw attention to yourself from the Po Lice.

I vote for the guy who said to shim the carb needles with a washer. On the same lines take the mufflers off and see if you can drill a couple of holes (~1/4") in both ends of the muffler to let some exhaust go straight through the can. If you are careful and do one hole at a time you will get the sound you want without it being too loud. If K&N makes an air cleaner for this bike install it. Those are all the cheap fixes. The next step is to replace the cams - probably not even close to worth the effort. What you'd be looking for is smoother throttle response, easier starting and a little noisier exhaust. Don't expect any real power increase.
