OK guys need help. I have had my 818 for a few years done and on the road it has always been a tight steer. Not tight like sized more like little to no castor.it won't self center. If you turn the wheel left of right it goes there and stays. You need to steer it back. I know lots of mods have been done for castor. All my stuff is stock FF parts except a Baer bumps steer kit.
Does anyone have pics or info of the upper control arm mods to get castor adjustments?

I know there was talking of shorting rear threaded arms to allow more adjustment

See attached pics of mine. I have never done an actual alignment does string alignment.

Any suggestions please
