Question about 2000 kawasaki ZR-7

1 Answer

Seriouse power dip at low rpm

I bought a ZR-7 2003 with 8000 km 3 months ago.
Verry happy with the bikebut Im experiencing problems.

At low rpm the bike reacts verry bad on the trotle. When I'm axelerating from full stop, power dissapears for half a second and it suddenly shocks alive. This is a problem in the first 3 gears. After thet the bikes settles this out.

Also in neutral the bike sputters around 1500 rpm, a small power dip.
I hope you undestand my problem.

Thanks in advanced

Plug gaps are incorrect. They are too tight. The gap of a plug has direct effect to ignition timing. Too tight and timing is advanced. Too fat and timing is retarded. use a decent wire gapping guage (not the 99cent key chain gapper) tool is a FEELER guage not force guage. gapped right and your problems solved.

Poor performance at low & high RPM


Did this problem come on all at once, or has it progressively gotton worse. Have you changed / cleaned your air filter. Have the carbs been cleaned, are the rubber manifolds without cracks,and are the carbs well sealed, when was the last time they were syncronized. what color are you plugs after a hard run, they should be a nice tan color, are they all firing. check to see if all the pipes are egually warm, do not burn yourself on them.

My 2008 Kawasaki ZX6R is having some stalling issues at low revs and stuttering issues while in motion. The bike has a power commander V, has been tuned on dyno, has k


firstly thankyou for adding a video allways helps

can u tell me how the bike performs in all revs ?

you say it has been dynoed how long ago ? have you made any changes since ? was it working fine when it left or has it been like it since u got it back from them ?

does it lack power taking off ?

first thoughts its almost certenly the carbs if not possibly a problem with the powercomander but id say 99% sure its carbs but if you took it to pros they shuld have set it all up right

what do it think it could be im thinking sounds like fuel mix problems low end maybe pilot ajustment needed possibly carb sync problem but all should of been addressed at the dyno center

can i also ask how long ago it was dynoed ?

as for something usefull for now here is a little rule for thigureing out air fuel mixes at low rpm and as a genral rule for setting up any stage of the carb idle mid and high rpm

        • NOTE: A rich problem gets worse as the engine heats up.
          • If the throttle is lightly "blipped" at idle, and the rpm drops below the set idle speed, then rises up to the set idle speed, the low speed mixture screws are probably set too rich: try 1/2 turn in, to lean the idle mixture.
        • NOTE: A lean problem gets better as the engine heats up.
          • If the throttle is lightly "blipped" at idle, and the rpm "hangs up" before dropping to the set idle speed, and there are no intake leaks and the idle speed is set at less than 1000 rpm, the mixture screws are probably too lean: try 1/2 turn out, to richen mixture. Be sure there are no intake leaks and the idle speed is set at less than 1000 rpm!

Yzf R6 2000 on W reg Runs Rough Low RPM


Hi, Darryl and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Old dead or bad fuel.
12. Fuel tank vent system plugged or carburetor vent line closed off.
13. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
14. Carburetor controls misadjusted.
15. Damaged carburetor.
16. Incorrect valve timing.
17. Weak or broken valve springs.
18. Damaged intake or exhaust valve.
19. Check for engine trouble codes

I am From Nepal. I bought this Yamaha FZ-16 few weeks ago. Total K.M run is 1567. Now my bike is giving off white smoke both in cold & hot condition and also in low as well as high RPM. Can figure out the reason for that. Can anyone help me out. I went to the Yamaha Care center, and they say that i need to replace my bike's ring piston.
