the spring in the clutch basket makes the pivot getting back to is free play place.. you may remove the right side clutch cover and remove pressure plate to figured it out what hapens there... or you may have the bering from the pivot arm jammed or something with it...

Need to know the year of the bike,but you may find that your powervalve is not working or lifting up to open the exhaust port fully.Does it rev cleanly otherwise?You could also have a carb issue if it doesn't.

I also find that if the bike has a high mileage the carbon build up in the expansion chamber will be too much and then it will need to be burnt out...this can improve the performance significantly.

Please leave some positive feedback for me if this solves your problem and get back to me if you need to.

Thanks

the floats are sticking, tap on the side if that dont do it take it off and clean it

It is just a pressure fit. Pry the shaft upward. Don't put pressure on the arm as it may bend.

All the best

Yr biek exist from 1986 to 2008. Looking at that number it might be 1991 or 1992 model. To be sure go to your local Kawa dealer and ask them, it is free

The cylinder and head nut on a 99 KX 125 is 18 ft-lb.

Proper proceedure would include a 17 or 19mm allen socket for the end of the axle, but normally you can get the axle nut loose by leaving the 2 pinch bolts tight in that end of the axle. So, in order-
1-remove axle nut. 2-remove 2 bolts holding the brake caliper to the fork and tie it back out of the way.3 loosen the pinch bolts at the bottom of both fork tubes, this will allow the axle to slide out. There will be a spacer on the rotor side of the wheel for the bearing, remember this when you reinstall.
Installation-1-clean and lightly grease the axle and inside the bearing seals. 2-install spacer on rotor side of the wheel. 3-reinstall wheel onto the forks,tighten axle nut,leave the pinch bolts loose. 4-with the pinch bolts loose, compress the forks down-this insures that they are parallel to each other. If they forks aren't parallel, they will wear the bushings and fork seals prematurely. 5-tighten the pinch bolts to about 15NM. 6-torque axle nut to 40NM. 7-reinstall caliper.

I would check the compression of the piston, the rings could be stuck and not have good compression. It should show 120 psi or more. Also can pull off the exhaust and look in the exhaust port to see the rings, piston, and cylinder walls. If the motor has a power valve make sure that is not gummed up or stuck. Mark C

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

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

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

I would use any good antifreeze as long as it has a corrosion inhibiter added to it. That will save your cylinder heads!

you might have to make sure that the carb is clear of any gunk ( very important )
