  1. Likely seized that forged piston.

    Oil over pressured

    I’d be looking for a kink or pinch point in the case vent line

    Valve shim question

    Being an electrical issue, starting up another thread with that in the topic header will certainly get you more/new readers and hits on that problem. Imho
  4. How cheap is cheap? If rest of the head is good and price is fair, I know I would certainly go for it if I needed one. The nipple is quite easy to make up from tubing. A press fit with backup by JB weld, done done and done. Or may got for thread tapping it and installing a tube-thread fitting. Plenty of options ... if you have skills to work it. Hope that helps!

    04 kx250f will not start

    Great. Have you examined that valve for amount of wear = cupping ? You may be best to replace the one valve now, avoid a failure later.

    Cast Piston durability

    Not likely. Kawasaki is not simply an assembly shop. Kawasaki Heavy Industries is a major world supplier of manufactured parts in multiple streams. Far beyond a bike builder. It is an interesting read and a broadening of knowledge about the scope of Kawi. Back to the question. What is the price difference? Really, what is the driver for why are you looking at wannabe jobber aftermarket parts?

    kx250f lost all power

    Rylee - what did you find?

    2012 kx250f engine noise

    Yes, generally.

    Numara piston kit

    Ok hold on folks. The topic is talking a 250 four stroke here. There is no such thing as lean burn piston melt down on a four stroke. That is a 2 stroke thing. I am curious to see more pictures of the piston, at different angles please. It will reveal the cause, (it won’t be “running lean”). Evan may be on point wrt the plug and octane, but let’s have a better look at the piston to figure it out.

    Yay another rebuild after 3 or 4 hours..

    Agreed, ditto.

    Cast Piston durability

    What is the comparison cost of a Kawasaki piston? Just wondering why looking at aftermarket pistons over genuine oem kawasaki?

    Won’t idle

    That is the accelerator pump diaphragm. Yes that would certainly cause problems, as example; poor performance, bogging. It would also shed bits and flakes which will clog jets and ports in the carb. A complete carb rebuild kit is what you need. Do that and you will be set. [emoji106].

    04 kx250f will not start

    A few possibilities: - a failing stator. Runs and sparks fine when it is cold, goes open circuit when it is hot - no spark, like kill switch - actual problem with wiring or kill switch itself. Corrosion, crack wire insulator, frayed wire .... - old fuel hose actually flakes off tiny bits of inner rubber. Clogs carb jets and ports. Put a New fuel line, clean the carb - a valve that is worn out, severely cupped can be drawn up and get stuck in the seat. Examine the valves and search the web for what is called a cupped valve then look for that. - valve clearance expended. Insufficient clearance or no clearance. Check and install new shims of correct thickness. It is common for the left intake valve to get to zero clearance. - a slipped camshaft sprocket. Causes the engine to go out of time. A slipped sprocket is not common but it does happen on the older 250F. Look for witness marks on the piston. Check cam lobs and sprocket index hole for alignment. - over temperature, overheat cutout. - failed TPS.

I slept sprocket is not common but it does happen especially on the older 250F - over temperature, overheat.
