Location: Saint Paul, MN
I will be attaching a Cozy Rocket sidecar to my 1970 R60/5 using a DMC subframe. Before I begin the install I plan on changing the fork oil. Any suggestions as to what viscosity will be the most appropriate with the sidecar? I know that most folks recommend a "heavier" oil for sidecar applications, and I'm just wondering what others are running in their airhead rigs.

I can't give you any advice, but when I installed modified triple trees on my Goldwing 1500, Sideffects recommended using Harley fork oil, I can't remember the weight they said to use, but do remember they said the sidecar rig required heavier fork oil. It worked well in the Wing.

Fork oil comes in a variety of viscosities. When ever I start riding a bike new to me I buy a bottle each of 5, 10, and 15 weight oil. The used bikes I buy usually need multiple fork oil changes anyway, so I experiment. It takes a couple of tries, but I usually find what I like in three or four tries. You can also blend them to get viscosities in between bottled weights. They have all been two wheelers, but I find the 5 to 7.5 weight usually does the trick.
I haven't started to fine tune my Wing/California rig yet. I have had bigger problems to solve.
Best of luck.
