I completely agree on the notchy stuff. I might have to give that oil a try.
I have never had any problems on any of my bikes (1992 750 Nighthawk and 2002 Connie) using standard automotive oil, either dino or synthetic, that had energy conserving on label. Of course I don't drag race and maybe that is where I would see the problem.So most likely you are using improper weight oil in at least the Connie as it specs 10-40.
So most likely you are using improper weight oil in at least the Connie as it specs 10-40.When Kawasaki wrote the spec prior to 1986 a 50wt multigrade oil probably didn't exist. 15wt is ok if ambient temperature is above -10C, 10wt is suitable for -20C. I have seen many charts showing 5W-30 is not suitable for temperatures above 30C.
TCro doesn't know Jack S**t about oil or much of anything else but he does keep Corona beer in the fridge!!

I use Motul 5100 10W-50 in both my bikes, it works very well.

As well as Oberon, Round Barn, Green Bush, Stella, and Bud Light for a friend.
Russell, 50 wt meets specs. The post I quoted stated "energy conserving" oil. By and large, energy conserving oils are 10W30 or THINNER.You're right. I've never bothered to read the workshop manual about this before as I've always used oil with the highest and lowest range I could find. The manual specifies 10W40, 10W50, 20W40, 20W50.

Yep already acknowleged that I was wrong. See my post (No 50) above.
Sunoco and Arco were both selling 20w-50 in 1975....I used a lot of it.
I guess I'm missing out on something with all these high end oils...Yes I understand that. In my last job oil from industrial machinery (admittedly not engines) was analysed reguarly and it lasted a whole lot longer than most expected. I know of people who rarely changed oil in their cars which were used every day and the cars ran for decades without problem. My wifes diesel car oil change interval is yearly or 15000km.
I run whatever SAE certified 10/40 dino I can get (usually Penziol) and change it once a year - (8-10K miles).
As an Air Cooled VW enthusiast, I find the fact that the oil remains IN THE ENGINE on the Connie a refreshing novelty and dont think about it other than that one cold evening per year when I change it...
