Have a new 605 and a bottle neck pump. Originally felt like driving on ice all the time....no feel of the road and pretty dancing. Grabbed one of those Borgenson pressure kits and pulled the flow valve out to find no shims at all which I assume is pretty typical for this pump from the factory. So, I put three shims in and it has helped a bit but not as much as I expected.
Wondered if anyone has been here before that could add some comments about their experience. The brochure says 3 shims places it around 1000 psi. I have two more shims that I could add but thought I would seek some input before pulling it apart again.
