I did a little bit of research (the first piece was learning how to search this forum!!) and I read everything here I could about oil. Sorry about posting redundancies!
I went to ye olde Canadian Tire and checked out both Rotella and Canadian Tires own Desiel oil. The Shell was only rated to a CJ -4 rating while their brand was rated to CI-4,CH-4,CF/SL. In an earlier post I said Rotella was rated to a CI-4 rating but that was from an old jug I had in the garage. So things definitely has changed!
My conclusions would be that the Canadian Tire brand has more ZDDP than the Rotella? But how much?
I have done some more digging, and based on what I have found, I will not be using Rotella. Based on the suggested ZDDP numbers of 1000-1200 ppm for Rotella I will be using something else. I got a bottle of the Castrol GTX diesel (as suggested by retired gentleman) and it is CI rated rather than CJ as the Rotella is. I looked at the various diesel oils at Wallmart and have found two types of their own brand. One is for personal diesels and the other is for agricultural diesels. The one for personal is CI rated while the agricultural use one had another designation (of course I can't remember what it was!) but I am inclined to think it might have a higher ZDDP content.
Re-reading this post has confirmed in my mind that I still don't know what I am going to be using in my xs!!! But Rotella I will not be. My engine is mild in performance but it does have a high performance cam and high tension valve springs. I just want to protect my efforts.
As an aside I found this article half way down I believe explaining the various oil designations CJ SM etc....
Actually John i am wrong I was able to find one shop locally that had the VR-1 racing oil in stock. I found an oil analysis of it on the web. The numbers can be all throughout the range depending on who does the testing. The lab called "Blackstone" tends to low ball numbers while this one here is somewhere in the middle between the really low and the really high figures I have seen.
mahanlee: Need help identifying this part. It came in a box from the previous owner. I have searched Google and Ebay and haven't found something similar. It has a short bolt with a flat side. The only place I figure it goes is underneath the battery box.

boxertwin1: I have a 76' XS and need petcocks for the tank. I don't want to rebuild, I want new ones. Weird, but you can only seem to buy right-sided ones. Any source for both sides?

pablosixfivezero: if your carbs aren't balanced, can that throw off your timing?

grizld1: Pablo, I suspect you may be joking here, but if the motor's shaking hard enough, I guess it could loosen the ignition fasteners enough to throw the timing off.

bikest: I'm looking for a list of front disc brakes(rotors) that will interchange with my 77 XS rotors. I down loaded the list from this site a few years ago but can't seem to locate it again? Thanks!

grizld1: The list you want was posted by jetmechmarty in this thread: www.xs650temp.proboards.com/thread/17334/brake-discs

slide: Mike, I suggest you consider a PMA from Hugh's Handbuilt. I have had one for two years and it works great. Couple that up with a new Pamco with the auto advance and you will be good to go for a long time. I think the cost may be less as well
