750 Brutale oil usage

I've recently noticed that my Brutale 750 seems to be burning oil. Lately I'm ridding the rev happy 'brute in the 8k-12k rpm range on long and winding Texas back roads. After riding out a full tank, the oil level will be lower, not low, but detectable that it burned some oil. Is this common? Mine is a 2004 with 4000 miles and I use Mobil 1 20w50. Perhaps my choice in oil or valve seals getting old due to age?

At 4000 miles you have barely broken in that engine.

Some oil flash off is normal. Is what yo see normal? I don't know. More than a liter in 1000 miles would be abnormal!!! Is it using that much?

Do you see blue smoke at any time? Hard acceleration or long decel from high rpm?

10w60 full synthetic is the oil your bike calls for.

I used to be fast....now I just dream about it.

10w60 full synthetic is the oil your bike calls for.
Service manual lists 20w-50 too.

I run Mobile 1 20w-50 in my 910R and doubt that oil choice is the cause. I would mark the oil level on your sight glass after sitting overnight and compare after a long ride + sitting overnight to see how much it has changed.

Cool 750 burns oil --

I can see my SPR engined SR burning oil at high revs and load .. but not enough to visibly lower the level .. I have so far done no oil top-ups between changes, mine's at 24000 km ...

My old 1.8Turbo Audi used around 0.5 to 1 litre per 2000 km --- Normal according to Audi my current 2,5TDI V6 does not use a drop extra between changes at 16000 km interval .. eventhough the car has done 420000 km ... Now go figure ..

20w50 is fine if you are in the temperature range for it. Texas counts.

I'd say maybe about 10 oz after each tank ~120 miles. Both times I have noticed the oil level was in the middle of range, maybe slightly higher. Then after the ride the oil level is just above the bottom mark, even after setting overnight. I ask mainly because previously I shifted before 8k and never notice the oil decrease in such a short period. Is increased oil burn common when running at higher revs?

Thumbs up ?

Ben;
Your rings are sticking, pull the plugs and put 10 drops of Kroil or a 50/50 mix of ATF and acetone and wait a day or so

Then add 6 oz of Marvel Mystery Oil to a full tank of gas and ride it for 100mi

Bet your oil consumption drops like a rock



I never have to add oil......5,000mi between changes......valve cover weeps but not enough to cause a drip, or fix

I put some Lucas compete system treatment in the oil and ran two tanks of it in the gas. No change so far. Today I decided to give the atf/acetone a try but was surprised in what the intakes looked like. The left two cylinder valves are pretty dirty and now I really feel that leaking valve seals are a contributing factor.

The pictures are of the cylinders left to right. All the vales had liquid setting on the edges that seemed to have a green ting to it that I assume is oil. All the spark plugs looked good, with the exception that the far left one had liquid on the threads but not the tip.

The last picture is of the oil level on the rear stand. Typically the level will be completely above the front hole when setting on the stand. So this is the amount of oil used after about 300 miles.
What do you guys think?
