Here you go, I'll make it pretty.

 

[va3ux]

Separate transmission or shared with the engine ?

 

[Robenstein]

Yamaha's are shared sump

 

[va3ux]

Viscosity held up well.

Oh no! You have to buy ultra special super expensive Motorcycle specific oil. If not, the carburetor won't carb, the battery won't bat, the pistons wont ### (well they just won't work either).

Sorry, couldn't help it. My grandfather retired from Shell Oil and we grew up using their products. Countless miles have been put on untold nubmers of motorcycle engines using Rotella.

 

[fat417]

Yep, I'm sticking with Rotella T. This is an air cooled, shaft drive, dual carburetor V-Twin. I can't figure out where all the copper is coming from. I'll go another 3000 and check again. Thanks for the comments.

 

[sunruh]

i would guess it is an inner sleeve on the clutch basket or similar.

 

[Gene K]

I will have to bow to Sunruh's expertise. I would have guessed copper containing sealers or something similar. I would think the potassium might be coming from flux in the oil cooler. Wonder if it might contain copper (I know the ones on some vehicles do).

 

[sunruh]

certainly could be an oil cooler.

without hands on inspection of the entire oil system it's only a guess.

something to observe and see if a trend develops or not.

That bike is capable of going 80k miles, but it will never get there at 2.5k miles a year ...
