So got this yellow gunk in the top of the crankcase and in the breather hose and box do I leave it or flush/clean the hose and box out ?

I believe that is from condensation.(water) How long since your last oil change? And when you do an oil change, run the engine for awhile. This wil get the water and oil mixed (not really) but it will get things moving. I've read that you can also get you engine hot and the remove the oil filler cap. This will allow the moisture to escape

heart disease?

Mayo.  Add bacon.  And ride longer.  Get that puppy warm.

Well ibhave taken the engine out and drained the oil was gunna put some engine flush and run before i drained it but flipping forgot soninthink I'm gunna get some cheap oil and runt with the engine flush then drain again

I would not get too carried away with that. If you research the board, you will not find many who have not experienced this.  A simple warm drain and refill with new filter should be all you need.

Have so few people ever made vinagrette dressing? 

It is oil flocculation.

Water gets into the crankcase when it cools in a humid environment.

When you run your bike, it (the water) boils off. 

If you do not run your bike long enough, it remains.

IF you run your bike several times for short periods, it will collect like that.


Go out and ride your bike at 7000 rpm for about 3 hours.  Doesn't matter the speed.  Just keep the sucker hot for a long time.  All that cheese will be gone.

somehow the same logic doesnt apply to a human being. we need to change the viscocity of our blood.

Quit talking dirty :P  Don't put that stuff on your salad either [puke]

If you remove the oil filler cap after your ride that will also help, since some of the hot moisture has a chance to escape.

So if I go for a 3 hour run I won't have any cholesterol.

Ducatiz means the bike, not you ;D  Don't get too concerned over this.  A common issue, and it will go away.  If your bike is equipped with an oil cooler covering it will (but not much) help.
