Just switched from 10w-30 motor oil in the forks to ATF-III.Was hopping to make the spring action a little softer. Not a big difference to me.Does using "real" fork oil make much difference?
I'm not against using real fork oil. Just takes some effort to find it.
I've been messing with the fork oil in my G5 this afternoon. I've been using Silkolene 10w fork oil, but lately I've felt the bike has been diving a bit on heavy braking. I'm 160 pounds, so not a heavyweight. I tried Silkolene 15w, expecting only a slight difference, but the forks barely compressed at all and the ride on a bumpy road was horrendous, rock hard. When I got back from my test ride I realised I'd put 300ml in each fork instead of the recommended 200ml, so perhaps this was to blame. Finally I mixed a quarter 15w to three quarters 10w, and put 200ml in each fork, and it seems about right. A longer ride tomorrow will tell.I should add, re the diving, that my front brake has always felt a bit grabby, so I fitted a set of Ferodo organic pads from Hitchcocks at the same time. Big improvement.
