I actually got the little b*stard past 3 by trying a different twisting technique. Instead of laying your palm on top of the ****, facing down, I put my palm underneath the **** and twisted that way. It gave me a load more leverage and I managed to get it all the way to 5.

I'll get the dealer to check it on its first service. I'm a relative lighty (80kg) so it only needs to be on 1, but I do need to set it higher when I take pillions...

 

I don't change mine much if at all, I just worried if the dial was set right, as in 1 on the **** was actually 1 on the shock
