Hi ,
I've just been through a similar process with my 650 2013, See recent posts. I didn't realise it had been lowered but it really didn't turn into bends properly, seemed to run wide. Turns out when I stripped it last week it had lowering links on it. I've now fitted standard ones
The forks on mine weren't lowered. either , which added to the odd handling.
So I've gone back to standard settings and see how it goes from there . See Gerts post and link
to setting up suspension.
