SOURCE: engine runs, but it will not rev up past 2000-3000 rpms,

are you turning the choke off after its warmed up? most will not run with the choke on and warmed up.

also try running it with the gas cap open to see if you have a vent issue in your tank. if air can't get in, then gas can't flow.

if not a choke or vent issue, then try this. turn the petcock off and then disconnect the fuel lines one at a time going into the carb. start with carb fuel line #1 disconnected (and the rest connected) and in a coffee can, turn petcock on and ignition too. fuel pump should come on momentarily and inject some fuel. see how the quantity looks. reconnect the line to carb #1 and repeat for carbs #2 - #4. your looking for a decrease in fuel to a couple of cylinders.

if all looks fine, i would then focus on the carb floats & jets. have the carbs been off for a good cleaning lately? modern fuel breaks down quickly and could cause a gumming condition in the carbs. spraying the sea foam or carb cleaner into the carbs is bypassing the everything in the carb bowl (but it means the spark plugs are ok) so there could be an obstruction. i would look there first.

if uncomfortable removing the bank of carbs, you can try a quick fix first. with the petcock closed, open the drain screws of each carb and let the gas drain out. go and buy some yamaha carb cleaner (liquid in a black bottle) at a yamaha motorcycle dealer. mix it in a separate container with gas as recommended. close the drain screws on each carb. pour the mixture into each fuel line feeding the carb and let it sit overnight. DO NOT POUR THIS MIXTURE INTO YOUR TANK. its not a fuel additive, but a cleaner that will not harm orings or gaskets, but it will not ignite with a spark plug. open the drain screws the next morning and let the mixture pour out. reconnect the fuel lines to the carbs and test drive it.

if that didn't work, then removing the carbs for a good cleaning is my next step. good luck.

SOURCE: GSXR 750 Slingshot wont rev past 5000rpm, with or without choke

I have seen this before a few things to do too make sure. First take the air filter out and shine a light use your fingers to move the slides up and down I suspect the springs that go on the slide is not seated in center you can tell from the slide going halfway and hanging up. Next, the boots on the slides only go on 1 way there is a notch on the carbs for them. I would guess this would fix you up if not we can get deeper into it with air-fuel mix screw settings.good luck

SOURCE: kawasaki 300 bayou won't rev up.

No guarantees but try this. Pull the slide from the throat of the carb. Now move the clip on the jet needle down one notch. This will richen the low end mix. Two notches may be needed but do one notch at the start.

Sputtering at 5000 rpm


AT 5000 RPM? What is the redline on the XT 600? I had a XT 500 Do not remember my year exactly, I was thinking the redline was close to 5000 RPM and if that is the case you could be possibly hitting a REV limiter or floating the valves.
Have you adjusted or checked the Valve clearance lately along with the Timing chain tensioner to be sure all are within adjustment specs?
The example you gave where it does it in 2nd gear, 3rd gear, I am sure it would do it in any gear as it sounds exactly as if teh engine is running up against a rev limiter or mechanical limits of teh valve train.

2006 zzr 600 dies when I drive it


The fuel system needs cleaning. Remove the carbs and petcock and clean them both out. The carbs have plugged jets which cause that. If you are not sure of how to properly clean out the carbs, I recommend that you take them to a shop or someone who knows how to.

I have recently put a jet kit in my 1999 kawasaki zx6E! It seems that when i get it at a really high RPM in 3rd, 4th, 5th and 6th gear, it spits and sputters like its starving for fuel. I was wondering if...


Your not reaching the RPM level for your rev limiter are you? The rev limiter will automatically shut fire off intermittently to keep the motor from damage at high RPM's. I have to admitt I am not up to par an all these newer bikes, but if you jetted the carbs, then I doubt you have a fuel pump on the bike. Most bikes with fuel pumps use fuel injection! Call the dealer who sold you the jets and ask them what else needs to be done, I am sure they will be glad to help.

Vmax will start and barely run only under full choke


If it can idle then still hope to help out else need to rebuild/clean carb out (cost a lot). If can idle then get yourself 2 bottles of fuel injector cleaners, pour 30ml to 5L fuel, let engine idle for 15 minutes, give some spur high3000 - 5000 RPM revs followed by a constant 3500 RPM rev for 15 sec then repeat process again another 3 times. Ride itnormally as if you are breaking it in until next time refuelling, add another 30ml and do the same process before riding it again. Do the same thing for the next 500 km.

My 96 magna starts, but wont rev up. I installed new plugs, drained the carbs, blew the fuel lines,changed the gas,checked all vacume lines,removed the air cleaner,& blew air through the top bowl...


put air cleaner back in the airbox as it is needed to create proper vacuum.blowing pressurized air into the openings on the carb could cause the float needle valve to stick to the seat.make sure your control cables are not in a bind, make sure fuel flows to the carb with pressure from pump (not just gravity feed)

Nearside carb problem on kawasaki zzr1100


Clean your carbs! Your floats might be sticking open a bit. Plus, all Kawasakis have a simple spring-actuated check valve in the fuel valve. This way, you can disconnect the fuel line without having to block the flow. Fuel could be leaking through the check valve. Your problem most liklely identifies dirty gasoline. Clean out your tank, your carbs, and change your fuel filter.

Zzr 1100 c model revs fine stationary and starts ok but when riding will not go faster than 50mph and stutters back and forth all the time


The spec sheet doesn't say if your model has fuel injection or carbs. Assuming carbs, disassemble and clean them. You will want the shop to balance and sync the carbs as well. This should get you back on the road in style.

Please rate this solution. Thanks!
