Does anyone know the ZDDP level of Shell Rotella T4 15W40 CK4?
Im looking for a JASO MA oil with 1200 ZDDP of greater.
Valvoline advised me that their motorcycle oils have 1120 ZDDP.
ZDDP level of Rotella CK4?

Right from their web site:
OEM Specifications and Approvals for Shell ROTELLA® T6 full synthetic heavy duty engine oil
API: CK-4, CJ-4, CI-4 PLUS, CI-4, CH-4
ACEA E9; JASO DH-2; Cummins CES 20086; Volvo VDS-4.5; Detroit Fluid Specification
(DFS) 93K222, Caterpillar ECF-2/ECF-3, MAN M3575, JASO MA/MA2,
Allison TES 439, MB-Approval 228.31
To me the real approval is the Allison TES 439 
Most modern motorcycle engines use slipper cam/lifter arrangement. Very few use real spinning lifters on a cam (Harley and I don't know who else), so anything above about 1,000 PPM is quite adequate.

Mobil 1 Racing 4T if you can afford it...
Whatever you use, most wet clutch bikes will wear the viscosity down significantly by 2-3K miles so plan on
changing it frequently. The Rotella will likely be the best option...changing frequently won't cost so much.
I recall the new CK-4 Rotella T4 15w40 formual did not change and still contains 1200 ppm Zinc and 1100 ppm Phosphorus 
Sorry I cannot find Shell documents to support this.

The CK-4 15w-40 dino "Triple Protection" T4 is also MA/MA2 advertised:

Why not run a dedicated Powersports oil if you're seeking specific ZDDP? Redline would be a good choice, see below. Low NOACK at 9% over 2000 Zinc, 0w40. Specs below. 
Good responses. The Rotella CK4 formula still looks good. I was under the (false) impression that they removed a lot of additives when they went to CK4 from CJ4. The Mobil 1 V Twin at 1750 ZDDP (and wet clutch compatible, according to them) looks like a winner. Its not JASO MA certified though, although I'm not sure that would matter in my application.
Likely, I will just try Rotella CK4 since its cheap, I have some in the garage, and the additive levels still look good.

It's the oils that are CK4/SN that have weaker additive packages because the SN spec limits ZDDP levels. If you can find any old CJ4/SM stuff then it'll be stout and ok to use.
Also be wary of oils that are JASO MA2 as this spec also limits ZDDP.
JASO MA is fine though.
