Hola, I moved from 700 feet to 7500 feet about 6 months ago and as the spring quickly approaches I am wanting to get the bike in shape. I had only a little time to ride in the fall, but of course the bike runs rough up here. I am wondering about high altitude jetting, Right now I have standard stock jetting with a Supertrap ISDS quiet series with about 8 plates. The airbox has been opended up and the screen removed running a K& N filter. 1) Anyone know the process for jetting the bike for altitude, and if so what jets I might try. Providing I try to do this myself 2) Any idea about what I can expect a dealer to charge me to do this for the bike. Mick A10 __________________________________________________ Do You Yahoo!?

For operation above 4,000 feet Kawasaki recommends changing to #145 main jet an #38 pilot jet. You can do it yourself in less than a hour and put a couple of washers under the needle and open up the idle bleed to 2 1/2 turns or so at the same time.

Although the manual recommends some leaner jets for high altitudes, a lot of guys wouldn't bother. The stock pilot jetting is pretty lean to start with, and the vacuum slide carb compensates for altitude pretty well.

I live at 6000 feet but often travel to your altitude and higher and also down to sea level. I run the stock muffler but tweety killing has given it a bit more flow. The stock 148 main jet works well in all situations. I have shimmed the needle up slightly. I wouldn't jet for high altitude because if you then travel lower you could have serious problems like a hole in your piston. You haven't mentioned turning out the pilot screw and it may not seem to make sense to go richer but that seems to make klrs run better everywhere. Bogdan

Mick, I ride my stock 01 A15 on a daily basis at 6600-7400 feet. I've never had any problem. Don Message: 9

The Kawasaki Shop Manual calls out a smaller main jet and pilot jet at altitudes above 3000'. The jets are called out on the part's fiche as the high altitude jets so its a no brainer to order - can even get the numbers from kawasaki.com. Pull the carb and switch the jets yourself. While you are in there you can drill out the slide which will also help restore a crisper throttle response at altitude. I live at 4700 hundred feet and ride mostly between 5000' and 9000'. I dropped my main jet another size and the bike ran crisper from 6000' up so I stuck with that arrangement until I installed a Dynajet kit where I'm using a 136 main.

In keeping with my time-honored maintenance philosophy ("If it ain't broke, try not to break it."), I've left stock jetting in place throughout the more than 90k mile life of my 2007.  This includes substantial time at 14,000 and 15,000 feet in the Andes, at which time the bike ran terribly.....but kept pulling no matter where I aimed it.  Remember that if you jet for 14,000 feet, you'll destroy things if you leave those jets in installed even briefly at lower elevations. Others see it differently, of course, and YMMV.....but leaving things alone is always an option.

I don't know anybody who dissed this procedure on a stock carb(EXCEPT YOU): Drill out EPA pilot screw cap, and set screw to 2 1/4 turns.

#ygrps-yiv-816283436 p {margin:0;}I have mine at 1 3/4 with a mildly modified exhaust. At the altitudes he's talking about, the stock lean idle jetting is actually better.  Besides, that screw only effects the idle mixture so anything beyond 1/8 throttle is moot. -Jeff Khoury

Obviously 90% of riding is done below 8000 ft. And taking the cap out makes adjustment easy on the road; if you have the right screw driver. Jeffrey #3
