I'm in the process of ordering Red Line motorcycle oil, 20W-50. Maybe one bottle of 20W-60 too when they had only 3bottles (almost 3 liter) in stock 2500ppm zinc.... http://www.redlineoil.com/product.aspx?pid=110
I hope clutch and gearbox will behave better. The ester based synthetic will fit my very warm engine too, 100-120C.

I'll report the result... hopefully smooth clutch without slip and smooth gear shifts, finding neautral when warm/hot.

And then there's Spectro -

Thanks, O'freen! I think I may have a go at the Spectro 20w50 next, if I can find some around here.

So far, I am not impressed with this Valvoline in my 750. When cold it's OK, but when hot I have trouble with shifting into 1st gear (that's a new one! Never had that before) and it hangs partway into 3rd unless I'm REAL deliberate with the shift. It has about 100 miles on it so far. Next I will try adding some ZDDP to see if it improves: if so, we'll know where the issue lies...

The included ZINC/Phos not enough in this valvoline 4stroke MC 20w50?
What will the added ZDDP tell you/us if the issues continue?

sorry about the ufcking gas thieves   >:(

If adding the ZDDP doesn't help, it means the detergent is high enough that it is washing the plates on the clutch, causing drag. I kinda expect this is the issue, since it took about 25 miles before the sticky-shift problem appeared. The Castrol 4T I had in it before was better, but it doesn't have the long-chain plymer strength it used to have when it was mineral-based oil, so when it gets hot it thins out more than it used to, and power drops off. This indicates the bearings and pistons skirts are dragging a bit.

I should caveat all this with: I've ridden all but about 15 of the 140,000+ miles this bike has on it, so it and I are closer than my wife and I, even... I know EVERYTHING about this particular 750K2, even its 'moods'.  Thus, it makes a great baseline from which to test this stuff.

I've always hoped that the cycles would learn to drive themselves in to my shop for repair w/ cash under the seat and a note stating 'my owner doesn't have a clue so PLEASE Fix me the right way !'   sometimes it helps to imagine.....   ::)  ;D

I hear THAT!

While we're on the dreams: I can't wait to "retire", when I will have a garage to work in and Hondas as far as the eye can see, to work on...
