kawasaki KLX 300 - Answered Questions & Fixed Issues - Page 3

i think you need to clean the exhaust pipe.sounds like it might be clogged.Dont know if this is a 2 stroke or not.They definately had problems

If it's the one I'm thinking of -it has a vacuum operated shutoff valve on the tank. So your leaky -read stuck- needle and seat only leak when the engine is turning over.

Pull the carb loose and roll over and remove the float bowl. drop the float pin and remove the float and needle. Find the vacuum line to the fuel valve and **** it open to flush out the needle and seat. When the fuel runs clean, put the needle and float back on and open the fuel valve again. If the upside down carbs holds back the fuel- it's fixed and you can put it back together.

All vehicles use the 10th character of the VIN number.

VIN (Vehicle Identification Number) Year Identifier: Year: 81 82 83 84 85 86 87 88 89 90 10th: B C D E F G H J K L

The head and cylinder can not be removed as a single unit. You will need to put the piston on TDC compression, then check for the cam positioning mark or marks to see where they line up. This is the exact positioning the cam gear must be reinstalled at. Remove the cam gear from the cam and the chain but first hook a piece of wire to the chain so it can't fall down into the crank area. Now the head can come off then the cylinder. The simple diagram is your engine. the other one is generic and shows alignment. Please rate my answer. Thanks.

check you coils and pick up i have had to replace the pick up on those little klf alot
Good Luck

Sounds like the relay contacts are bent or welded closed or the solenoid is stuck. Check the solenoid first by removing the small wire from it and seeing if the starter stops turning. If it does not stop, the contacts in the solenoid are stuck closed.

the easiest way i find is to drain the resevoir, refil and drain with a vaccuum bleeder until clean fluid comes through the bleeder (topping up the resevoir as you do so)
this works for front or rear brakes.
hope this helps

The battery may be going bad. Try new spark plugs first. Carbon on the old plugs can rob spark.

make sure u have the right compression and after 5 years of not kicking it a 300 is probably pretty tough to kick. but u should be ok

Kawasaki 10w40 motor oil. This is the oem recommended oil... Good luck and happy riding.

Lock the bike in gear so the sprocket won't turn. Remember that the locknut is a left-hand thread and may have locktite on. If the sprocket still turns then get a friend to hold the drivechain tight and wrap it around the sprocket, this should "jam" the sprocket and not allow it to move.

Wath was before problems starting?
Details needed.

sounds like it may need clutch adjustment,may be an adjustment on cable at the motor turn it out couple turns and try again,theres also an adjustment at the lever,try that also,based on what you have described if the clutch is not fully engaged when shift into 1st gear it will shut down on you,also if you have it running with clutch lever pulled in and it wants to still move forward that is the problem,hope that helps.

how do i adjust the vaulves

Hi, all you need to do is clean the carburetor.

I expect the alternator is open circuit or you have a wire off.
Is there any voltage coming out of the Voltage regulator?

Depending of the bike , the tensioner should be a Teflon push plate or a metal plate which pushes on the chain to reduce the slack in the chain .Adjustment can be made manually from the back of the cylinders but all tensioner are different .Some do have a spring which could need replacement . sometimes if the timing chain is too old it make noise due to the tensioner out to the maximum tension and does not apply enough pressure on the chain and therefore noise and slight vibration .

If the bike idles when you appy a little choke you may have a clogged carburator. The fuel that we get now is very unstable and gums up very quickly. I would suggest cleaning the carburator and flushing the fuel out of the fuel tank. the carb is very intricalte and should be serviced by a qualified technician.
I hope that this helps,

You need to take your carburetor off the motorcycle . disassemble , and clean it. Be sure to inspect the intake manifold for cracks and separation this could be a source of your issues. Pay close attention to the the slow jet and the slow jet passageway through the body of the carburetor. If the carburetor body passageways and the jets are open/clear,and you have the mixture settings set correctly (stock). Your idle problem should be solved.

this is normal. The heat from the engine is no longer being circulated by the water pump, this causes the pressure to rise. The coolant is expelled into the coolant tank. The coolant is drawn back into the radiator as it cools. If the coolant level is low when checked ( bike cool ) then there may be another problem. Over heating due to stuck thermostat or blown head gasket. Be sure the coolant overflow tank hose is not cracked or leaking.
