I actually rebuilt my SE forks when I got them some years ago. And there is probably less than 1000miles on them. The SE forks seem to be in great working order and the internals seem pristine (I had them totally apart this week). The specific issue i have is that my SP forks after the rebuild do not "shoot back" after being compressed like the SE forks do.
It is very noticeable but is this the norm for SP forks. I am so worried of a low side caused by the forks bottoming out because I have Repsol SP fairings on the bike
