I just had 3rd oil change since rebuilt. I noticed the clear fresh oil turns dark only after less than a minute of engine warm up. Is this normal?

 

[timberfoot]

I think it's pretty normal. There is always some old oil left over in the engine. That stains the new oil a bit.

 

[skypupbob]

Yes, normal. Some engines tend to turn the oil dark rather quickly, and the KLR is one of those.
On the other hand, my 23 year old Honda lawnmowers oil looks like new after mowing all summer.

My previous Africa Twin oil looked new after 2,000mi. My 2022 klr oil is almost pitch black after only 500mi.
Don’t base oil changes on oil color.

Thanks. I noticed I didn't have to put as much oil as 2nd oil change, so yeah that small volume of old oil most likely stained the new oil.

I'll suggest that too many people are too lazy or too much of a hurry to tilt their bikes from LH to RH Several Times to drain the hollow shafts, nooks & crannies that many motorcycle engines have.

Maybe THAT is why Thailand changed the recommended oil quantity? They didn't tilt them either!

True that. I am making rear stand for the next oil change.

Same here, very black when it came out.

I have always done this...

I believe the clutch dust is what makes your oil dirty, normal.

I don't think a clutch that will easily last 100,000 miles is shedding much "dust" in the oil.

You will still leave a lot of old oil in the engine with vertical position only during an oil change.

After doing a vertical drain only, take it off the stand & tilt it side to side, holding the angle for a minute or two each time.
You might be surprised.

Has anyone completely reassembled an engine? How much oil did that require vs a normal oil change? That's how much oil is suspended in the motor.
