kawasaki KX 125 - Answered Questions & Fixed Issues - Page 5

Well - not knowing the condition of the bike it could be a lot of things. I would start with a fresh spark plug, fresh fuel and a clean air filter. You say you already did the carb, reeds and top end - good. I assume you set the float level correctly. Did you pull out the petc0ck from the fuel tank - theres a filter that might be plugged up. Check your exhaust system for plugs - I've seen mice nest in pipes over the winter. If all this fails, look into your power valve system to ensure it's working and adjusted properly. If so, then do a leak down test - you might have a lower end leak. That's the best I can do without seeing or hearing it run. Hope this helped!

is it loosing water mate and the mix is 32-1 mate and get some good oil if it loosing water the head gasket has gone if it not this ckeck the jeting on the carb good look

check fuel line.... from tank to carburator.... probably your having fuel problem, there might have some foriegn object that got stock up... check out the main jet....

yes you can but the best is 20/40

15.89-16.16 ounces. Here is an added bonus.

Most likely reason for this is water pump seal

There should be no oil coming out of the tail pipe at all. You do not say what type of machine it is, therefore I must assume it is a two stroke. Check the oil delivery/mixture, somewhere you are getting too much oil into the gas.
If it is a four stroke there may be a problem with worn rings or valve stem seals.

What bike is this

ok, its been a while, but if i remember right, on one end of the shock you should see a series of "notches". what you'll need is a spanner wrench to rotate the shock until it catches on the right "notch" for the ride hight you want. hope this helps

The same wat you took it off. No adjustment should be needed unless you have tampered with it previously

if the bike is to small for your the BEST thing to do is move up in bikes, if you can ride a 85 you'll have no problem on a 125, if your feet dont reach ground thats fine your are not on the ground when your flying in the air over that 100 foot double.
Good luck

WOW, did you buy a basket case?? anyways you need it for the bike to run right. Look it up on world of powersports, click shop parts and then your make, yr, model. they will have all the parts and price's. remember if your bike has been bored you WILL need to mod the power vavle. if your not sure how to grind it RIGHT call millennium technologies http://www.mt-llc.com/. they are one of leaders in cylinder repair and only one of two shops i trust to do that kind of work.
Good luck

Never try to "out engineer" the engineers. Just install a fresh unaltered set of reeds. You may want to ask the previous owner if the main jet was ever changed. If so, ask the dealer for a stock main jet.

strip the carb down, check the float level it mite be out also check for a blocked jet. its got tobe one or the other that is wrong to cause fuel to overflow. hope this helps

weak

It maybe some gear linking the shifter and transmission may have slipped off.The gears are to be checked.Try adjusting the clutch cable, if its got loose.Look on the right side bewteen the front cylinder and the radiator and there you will see the clutch cable and can be adjusted from there.Also check the shifter and shifter bracket.If the bolts are got loose or any thing obstructing the shifter , then it has to be cleaned.The input shaft will stop turning with the clutch pulled in so they tranny won't shift 'til you let it out a bit.--------Get the clutch, shifter, shifter brackets,the block in gear, the transmission needs to be inspected.A proper servicing for the parts is required. ------------ This should help.Thanks.Helpmech.

First place I'd check is the carbs - make sure the choke isn't engaged!
Choke on = easy start + easy idle + easy revs + bog under load.

Too much air (hole in the airbox, hose off the airbox) can do this too.

there may be some dirt in the float valve jet, the carb needs cleaning

Remove the right side cover and check the operation of the side case clutch lever by looking at it from the inside. If it is operating freely and the cam on the arm that pushes the clutch release pin is not worn out, the problem would be the fiber friction clutch plates. Did someone use synthetic oil in the gear box? Oil with "Special" lubricants? These can shrink the cork on the plates and cause the clutch to slip. Some synthetics can swell the cork and cause the clutch to grab and not disengage. If swelling or shrinkage of the plates has happened then the repair is to install new plates. Potentially, grooves may be worn in the inner and/or outer clutch hubs. This would prevent proper operation of the clutch. The repair there is new clutch inner hub (if worn), or clutch outer hub as needed. A worn needle bearing could also be the cause if the clutch will not disengage.
