Hey.. Time for a qualified professional to take a look at your fuel system... First, there is NO reason to "jet an engine high" unless there has been extensive modifications...(and ones that actually work!!!)... have the PROFESSIONAL clean and set the carbs... the gas in your oil is coming from the carburetors..
PLEASE take this entire bike to a PROFESSIONAL.. let them FIX it.. and TELL them about the jets.. they know what is correct..let them FIX IT!!

SOURCE: Which size Jet Kit for 800 Vulcan Classic?

general rule of thumb is to go up about 10 jet sizes,unfortunately it is a bit of trial and error,and you may have to swap out diferrent sizes to get the bike running right,(jets are quite cheap though)but first step about 10 sizes from standard,your local dealer should be able to tell you what jets are in it and supply replacements,if you change to a hgh flow aftermarket air filter you may have to change jet sizes again as changing the filter may effect the mixture ratio in the carbs,,hope this helps

SOURCE: my ninja loses power in the wind

Do you have a "RAM AIR" system on that bike, if so that may be what happens when you ride into a headwind. The bike may be running a little lean and with the extra intake pressure goes too lean.

SOURCE: Air box and crank case fuel flooding problem

Well there only one way the fuel can get into the crankcase and that's from the fuel tank. The petcock must be draining and the float needles are not stopping the fuel flow. Do you have a prime position on the petcock? If so do not run the bike in the position. Try topping the tank off with gas and letting it sit for a while and see is the gas has gone down and then check the crankcase and see if there's fuel in it again. i still say its got to be your petcock.

SOURCE: i just purchased a 2001 zx6r and i put 1/3 seafoam

Sounds like fuel starvation, remove airbox lid and check the slides in the carbs are not stuck, this sometimes happens when the fuel in the carbs becomes old and forms a stickey bond between the needle and main jet diffuser, you may benefit from a complete overahaul of the carbs again, 2 years is a long time, and i would not find it unusual to do this anualy unless you continue to use the bike, remove the slides and check the diapram condition for holes, remove the mainjets clean, allso the pilot jets and clean them using a wire from a wire brush push through the jet twisting and pusshing, also blow out the holes the jet screws into, remove the float valves and clean them with some wire wool taking care not to damage the rubber tip, and the valve seating should also be cleaned,

Why does my 99 zx6r keep stalling when coming to a stop?


Hi, William and the usual suspects are:
1. Idle circuit and transfer ports clogged.
2. Air fuel mixture adjustment too lean.
3. Pilot jet clogged.
4. Faulty accelerator pump.
5. Float level too low.
6. Float bowl contaminated old fuel, water, dirt, rust, etc.
7. Float bowl vent or overflow tube clogged.
8. Fuel flow to carburetor restricted.
9. Intake manifold leak.
10. The gas cap is not venting properly or fuel tank venting system blocked.
11. Vacuum line from intake manifold to petcock broken, cracked, or not attached, carburetor vent line plugged.
12. Needle and seat stuck closed in the float bowl.

My Kawasaki zx6r 2009 keeps displaying f1 and with a flashing red light. The bike runs fine. Sometimes shuts off while warming up. how do I fix it?


it actually means fault indicator and doesn't deal solely with the fuel injection.

put the key in the ignition and turn it on, but don't start the bike. use the mode button to go to the odometer display, then hold the mode button down for 2 seconds. the code should be displayed.

come back when you have the code

Bike wont start


when you drilled out the pilot jet you destroyed it. Even if you have jewelers bits they are to big. One drill bit size is 6 to 10 jet sizes. Replace the pilot jets, you are running WAYYYYY to rich at idle.

So I bought an 95 zx6r ninja stock with 6000 miles last week. I noticed that the fan does not turn on period. While riding obviously its no big deal, but in traffic I have to shut the bike off sometimes....


check your Thermostat is engaging, if you have a haynes/clymer manual it will show you how.

check that the radiator is filled 100% from the cap and bled of air by squeezing the hoses,


anything else about the F model is pretty simple,

i used to use www.kawiforums.com for my 95 ZX6R but its an american site, so some of it didnt make sense to me.

Running to rich on my S&S carb


You failed to tell me what year and model bike you have this S&S carb installed. If you have the carb on a Sportster, it should have a 26.5 slow jet and a 66 main jet in it. If it's on a Big Twin, it should be jetted with a 28 slow jet and a 70 main jet. Of course, depending on the exhaust system, the air filter, other equipment on the bike, and your location, the jetting could vary a step or two either side of these sizes I've given you. Another area of concern with the S&S "Super E" model is the adjustment of the accelerator pump. Most people get the accelerator pump set too rich with too large of a "pump shot". This adjustment has to be made according to the way the bike reacts to a roll on of the throttle while riding. You cannot get this set correctly by adjusting it in the shop. For instructions on how to jet your carb, go to the S&S Cycles website and click on "Tech Info". Then click on "Installation instructions" and "fuel systems". Look for the the instruction sheet number 51-1012. http://www.sscycle.com/instructions/instructionslist.php?x_cat=24 This will give you a starting point to jetting yoru carb. Keep in mind that when dealing with an air cooled engine, it's better to be slightly rich rather than too lean. Lean mixtures create a lot of heat.

Good Luck
Steve

Kawasaki Kit ECU on '07 ZX-6R race bike


Hi, Simon_mcaule the answer to this question is way above my pay grade for this situation, I would call or visit my local dealer or reputable race shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. Not being able to pull codes really puts you in the dark, could be a faulty connection in the ignition circuit or you may have a temperamental ECM that doesn't like aftermarket performance parts, a face to face with your fuel tuner may also be in order.

99 gsxr 750 losing power after 10k rpm if you have


The carburetor jets, there are 3 bands; A low, mid range and high range rpms. 10k would fall in the Mid range power. I would let the bike warm up a little bit and tweak the middle knob on the left side of the bike and keep in mind you need the right mixture so turn it quarter turn one way at a time per testing the mid range rpms while riding, tweaking 1/4 turns in between tests. If it gets worse, turn it the other direction until you find that sweet spot in the mixture of fuel/oxygen.
