If it didn't pop after the valve adjustment, try adjusting the valves again. Popping out the exhaust usually indicates a burned exhaust valve. The valve doesn't seat all the way around and air/fuel mixture is getting into the exhaust header on the compression stroke and igniting from header heat. The reason this doesn't happen at higher rpms is the amount of time for the air/fuel to leak it really short.

Replace it. Get a floor model at lower cost

Could be dirt in a fuel jet in the carb. You cap purchase a fuel cleaner to put in the gas tank and if that does not work the carb will have to be cleaned.

have you checked /tested the kill switch

p[robably neither but a broken return spring on the selector lever

Replace the glow plugs one or more are shorted

Try more!

This is most likely because you have it in gear going down hill with the throttle closed. This turns the engine into an air brake, and the sound you hear is the compressed air being released during the exhaust cycle.

check spark plug

follow this steps and fix it. God bless you

• Make sure the key and kill switch are both in the "on" position. Ensure that the proper starting procedures for your bike are followed. Is it in neutral? Clutch pulled in? Gas in the tank? Then try to start your bike. Does it turn over? If not, check to see that the battery is properly connected and the terminals are not corroded. If they're loose or dirty, clean and tighten them. Then, using a voltmeter that measures ac/dc and ohms, check to see that your battery has enough charge to crank the engine. If not, replace or charge your battery and try again. If it still doesn't turn over, there may be a loose connection between your battery and starter; a bad ignition or starter switchl or a bad safety relay. Check a repair manual for proper testing procedures for your bike, as each motorcycle differs.
• 2 If your bike turns over but doesn't catch, check to see that it's getting fuel. If the bike has a fuel petcock, make sure it is in the "on" (or, on certain bikes, "prime") position. Then remove the main fuel hose and check to see that fuel is flowing freely. If fuel isn't getting to the carburetor or injection system, your bike won't run. If that's the case, your problem is likely something in the fuel system. If fuel is flowing freely, reattach the lines. If it's not, check to see if the fuel filter is clogged, if a line is pinched or if the petcock is working properly. One way to determine if the problem is in your fuel system is to put a few drops of fresh gas into each spark-plug hole, replace the plugs and turn the bike over. If it starts and then quits, the problem is likely in the fuel system.
• 3 If you're getting fuel and the bike turns over but still doesn't catch or start, check the spark plug or plugs. Start by pulling off a spark plug wire, then removing a plug using the spark plug socket supplied in your bike's toolkit. Now inspect the plug. It should not be wet (usually caused by fuel, when the plug is not firing) or coated in carbon/burned oil deposits. Now check to see if the bike is getting spark. Although you can get a special, insulated set of pliers to hold the plug, there's a "quick and dirty" method for this: After reattaching the plug wire, lay the threaded part of the plug against the engine (not over the plug hole, as the spark could ignite any fuel that is blown out when you try to start it). Now, making sure you're not in contact with the engine or plug, hit the starter. You should see a nice blue spark. If you don't, make sure the threaded portion of the plug is touching the engine (but the electrode is not) and try again. If you still don't see a spark, you either have a bad plug or a problem with the electrical system. Check to see that all the ignition wires are properly connected and that you can't see any cracks in the wires. If the wires are cracked, they should be replaced. If you're still not getting spark, it's time to consult a repair manual or call a mechanic.
• 4 If you've got fuel and spark, ascertain that your bike is getting enough air. Start by pulling off the air filter. If it's too dirty, you won't get the proper mixture of air and fuel in the carburetor or injection system. If it's clean, check to see that the air box is properly connected-- a loose hose or air leak can feed too much air into the system. If your bike is equipped with a choke, ensure that it's able to move freely and is not stuck in the "on" or "off" position.
• 5 If you've followed these steps and still can't get your bike to run, call in an expert. If you think you've narrowed down the source of the problem, describe the steps you've taken to point the mechanic in the right direction.

I hooked up my battery backwards and now that I re dis it right it wont start

If the carburetor was properly cleaned including the teeter-totter float needle then you may just have accidentally changed the setting screws. Try setting the the high end and low end adjustment screws the standard settings are: Low speed screw: 3/4 turns out (+ or - 1/4 turn for fine tuning) high speed screw: 1 1/4 turns out (+ or - 1/4 turn for fine tuning) If the previous owner rebuilt the whole machine but could not figure out why the boat would not rev out, the next thing to do is remove the water box and and split the halves. http://www.bikebandit.com/houseofmotorcycles/1995-kawasaki-750-ss-jh750a4/o/m3253#sch27834 If a mouse nest has been built in the exhaust system the extra back pressure could be the problem. If the exhaust coupler has broken rubber tubes, has come apart, or has not been put together correctly that might also be the cause of the problem. http://www.bikebandit.com/houseofmotorcycles/1995-kawasaki-750-ss-jh750a4/o/m3253#sch29444

Always keep the water pressure low, when the water coming out of the side of machine is cold you should turn down pressure. Engine on first then water, water turned off then wait 10 seconds and turn off machine. If you go out on a ride then park it for say an hour and find water in cylinders I would replace gasket. My shop time on all the J series engines is 20 minutes for head gasket.

Yes the key does have to be turned to FSS to allow key removal to open tank or luggage

Hi,
Check the spark plug wires...they are bad and the spark is jumping when under load...

Your 440 jet ski does not have a gear box. If you are referring to what looks like a filler cap on the front of the motor, that is the generator/flywheel cover and it is a dry compartment and should remain that way.

That is a link to the G series manual for 1972-86 models.

First removed the gas tank, seats, crankcase oil breather tank mountingscrew, and the right side black panel that covers the radiator cap among otherthings. The choke cable attaches to a boot which screws in a jet that is heldin place by a spring. The boot is not held on more than hand tight but it'sreally hard to get in there with even average width fingers. Unscrewed the boot and jet assembly, removed it from the cable, and removedthe boot as well (right angle pipe with rubber cover). The Y connection on thechoke cable has its own snap anchor next to the radiator cap which helped inplacement. Verify you have the correct length choke cable by pre-routing it over theframe of the bike before you swap the cables. After that, pull out the carbends of the cable and feed it through to the front of the bike, then remove itfrom the handlebar housing. It's easier to unscrew that way. Route and attach the carb ends of the new cable first as well. It'll giveyou the extra length you need to get the jet assemblies back onto the carbswith a lot less hassle. The hardest part was screwing the boots back into the carbsbecause of the lack of workspace. Follow this diagram,and see if it can help you additionally. AV

There is a temp switch and a relay to run your fan.
