2002 Kawasaki zx7r cuts out between 4 and 6 rpm


check for sticking floats and float valves to sort out the spitting gas and lift the needles by 1 or 2 notches to sort the 4000-6000 problem

cat is probably plugged. rev it up and check the pressure coming out of the exhaust pipe. if its weak then replace the cat with a test pipe to make certain.

I have an '84 xj900, runs well but wont go over 4000rpm


Hi, Jason 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. Dirty air filter.
10. Intake air leak.
11. Water, dirt, or rust in the fuel system.
12. Carburetor damaged, contaminated, sticky float, plugged jets.
13. Multiple carburetors out of sync.
14. Fuel filter clogged.
15. Old or contaminated fuel.
16. Fuel tank vent system plugged or carb vent line closed off.
17. Gas cap diaphragm valve faulty.
18. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
19. Carburetor controls misadjusted.
20. Incorrect valve timing.
21. Valve springs floating, weak, or broken.
22. Damaged intake or exhaust valve.
23. Incompatible performance parts.
24. Control module may be in "LIMP" mode
25. Check for engine trouble codes.

I have 1999 zx9r that back fires and throw flame out the pipe when i rev it up counld this be my packing in muffler gone or what help please!


you either have a severe missfire or its running too rich if it iworse when riding the bike and you do a rapid gear change to a lower gear and it pops and bangs a lot its air being sucked into the exhaust system from a leak in the exhaust joint or gasket failure check for blows around the exhaust clollectors or splits around the bracket that holds the pipe on to the bike frame

Dose the engine have a rev limiter fitted when road testing bike popping back through exhaust on over run / when taken to high rev holding back on road test


Most engines with cdi boxes have rev limiters. Popping or backfiring could also be caused by low back pressure (aftermarket muffler) and most commonly bad exhaust gaskets in the head.

I have a 97 gsxr 600 bike has rebuilt 99 motor with 97 carbs DandD exhaust K&N filter and stage 1 dyno jet kit. it runs great over 3500 - 4000 rpm. It also idles very nice, very smooth. Sounds smooth...


if you had cam overlap then it wouldnt start and when you pushed the starter if would smash the valves together, if it runs ok every where else then i would say its a crab fuel problem and at that rev range it would be pilot jets as the mains dont come into use at that rev range you should take your bike to your local dyno center and have them run it up they will sort you problem

In neutral car is not going more then 4000 rpm


The 300M is equiped with a rev-limiter. The technology is designed to protect the engine. It keeps you from blowing it up when it has no load on it...If it is driving and shifting ok, and you have no check engine light on...there is nothing wrong.
Why would want to rev the engine past 4000 rpm in neutral anyway? Max torque comes in around 3950 RPM...
If you keep reving it up in neutral you might throw the computer in to LIMP mode, then you wont go no where.
Hope this answers your question...
