Changing the oil in my track 93 ZXR400 front forks. I picked up some 10w Motul on Friday and changed the oil today in just one fork.
The return on the shock I have changed is a lot slower than the unchanged one. Doesn't seem to be any noticeable difference in compression rate.
I am not sure what weight oil is in the unchanged one but standard is 5w with 85mm air gap.
Just to add some more info into the mix I just checked the zxrworld.co.uk forums and the racers there seem to use 7.5w.
So my question is should I just change the other one to the 10w as well and give it a go, change it later if it doesn't work out, or would it be recommended to just go lighter weight now?
Thanks
