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

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.

To lower you seat on you bike you will have you stiffen you suspension and your seat will go down?

yes you can but the best is 20/40

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.

If this is a 2 stroke engine it does not require an oil change.
If this is a 4 stroke engine most motorcycle manufacturers recommend 10W40 oil and an engine that size should require approximately 3 QTS of oil. However, personally I have always used 20W50 in all of my 4 strke motorcycle engines. You also mentioned a problem what is the problem with the KX 125?

Are you certain the throttle butterfly or slide (depending on what model bike you have) is seated...if the actual throttle in the carb throat is not closing, starting bike cold will be very difficult as you are feeding in too much air.

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

sounds like the timing is off or you have cracked rings on the piston.

The engine will require running in as the bore must have been scorred as well and should have been scoured with wire wool to allow the rings to bed in.
Is the tapping coming from what you have replaced?
Find a long screwdriver and put the tip on the top of the engine and the handle up against your ear and listen. Locate the source of the knocking/tapping and then you will know the cause and area.
Hope that helps.

Sounds like there could be a problem with the main jet not delivering sufficient fuel for normal running. Clean out the carb and check the jets and passages for obstructions and dirt.

More than likely it is something very simple. Have you cleaned the air filter lately??

I am not familiar with a 00 kx 125. Typically, a clutch cable has a barrel (or other special shaped piece) on the end which clips into a holder on the lever OR there is a threaded rod with two nuts on it to allow for adjustment.I hope this helps.Thanks for your interest in FixYa.com

hi first off you must remove all the water as soon as possible as corrosion will occure very quickly on the big end and main bearings thus you will have to strip the engine to replace them so the quicker you remove the water the better, it may be when you removed the head the water that was inside the water jackets has gone inside the engine, however you do have a base gasket under the barrel that may have torn and leaked water into the engine, it would be best if you drain all the water out before you start removing the barrel, remove the piston by removing a circlip and tapping the gugeon pin out carefully remove the small end bearing, dry this and oil it, once all this is done useing compresed air blow out the water, if no air is availabe turn the engine upside down and alow water to run out, use some wd40 and engine oil to get around the bearings and remove the exsess oil when happy all is lubricated, when replacing piston ensure correct fitment arow facing exhaust port, if no arowlocate the piston rings in corect position and fit with the locating pins at the rear, any questions ,paul

You will have to take it to a suspension shop. You need special tools to disassemble and recharge mono shocks. I'm surprised your friend was able to get any oil out of it though, normally this requires disassembly. You might have a problem with the shock. Either way, take it to a suspension shop. They usually don't charge much for recharging them.

Clean the carb. Some trash is partially blocking the main jet.
