So 136000km on the first rebuild? Its impressing, good engines!:thumbup1:

dont give up JJ, you will win at the end :)

turboguzzi you seem to know how much oil its suppose to be up in the tank, in the system and down in the crankcase, please inform us? When the oil valve is ok.

Hei guys,i found something new! Yesterday it was warmer than today (no smoke) and today at start-up smoke..it's voodoo like i saydoh

Can you do us all favour, ride the bike and let engine idle a minute, check oil level, if its maks drain crankcase and measure, then drain frame and measure. Let the drainplug stay open in crankcase, then you will see if its seeping down from frame trough the valve. Dont do this test before you have full level on the measure stick, just let it idle for longer time so oil is up there.

I did a test: i drained all the oil from engine and the tank. I put back 2L in tank..i waited until drained in the tank and then i put on this almoust 600ML until the edge of the tank..after almoust 1hour the oil which drained in the crankase was about 130-150ML..without to turn the engine on. So my question is..the oil valve is good or bad?

Haha are we back to the stupid valve againdoh Its hard to tell where the oil came from after only 1hour, did you drain cold or hot? So you had 2,6l oil coming out total?We still didnt get any answear about how much oil its in the crankcase when its full up in the tank..

As stated before, your new valve seals could have been damaged when installed, easily done. If this is the case then this will require you to remove the head and have the seals replaced again. As JJ stated, make sure the valve stems are carefully checked and burrs removed before new seals are installed to keep from tearing or damaging them.

The check valve is easily replaced, order the rubber piece and the ball plus order a new clutch cover gasket. Drain oil, remove clutch cover. Valve is in the crankcase at the bottom. Pull it out, clean the cavity behind it, install new ball and rubber piece. Make sure the spring behind the ball is there and clean.

This may not be the problem but now you will know it is in good shape.

I assume you know to check oil level after a warm up and short ride. This allows the oil to expand a bit and all excess oil in crankcase to be in the tank where you can get an accurate measurement. Measure right after engine shut off, bike vertical.

I feel like that some of the frustration shown in these posts that there is some translation error and you may not be understanding exactly what is being said here. Please ask for clarification if you are not understanding. :D

As I had said last week already, please drain ALL oil, every drop of oil from your motor, tank, everything. Put in 1.8l ONLY, and Please forget worrying about that valve, please???

Run it several times over several days to notice smoke.

I Repeat,
Completely ignore that valve right now and everything you've heard of it, and drain ALL oil and add back in 2.8L, NO more. Run it ! please?

Why do you want him to run bike 1l short of oil? I dont recomend you running the bike with only 1,8l oil! Dont waste anymore time on this, remove head and change the seals! If you remove head take picture inside.

Whatever the amount is , I was thinking it was 1.8L but maybe that's my KLX's . Good catch . I'm rather frustrated at these dragging on things I guess , it so simple to verify and move on .


BTW Danimalu , also very common for leaking seal(s) to not smoke every time . I have a KLX that only smokes every 2 or 3 times and when it does it's a cloud . That's a bad seal.

This engine have 2,8l with filter change, so 2,6l that he drained is normal without filterchange.

No wonder I go through so much oil in a year , I quit measuring and just keep dumping till full, plus a little. :innocent:

:oops2: :funmeteryes:

at hot! i forgot to measure from crankase.
