RE: Re-Springing the Bike
530 is UBER fair for good suspension work...you may also want to try stig at pps in anaheim, ca.
those guys at GP...guess what?they keep records of all work they do...unlike some other shops...
my friend got his F4 shocks done there last year...i wanted his forks but he didn't know the specs, called dave and they gave him everything he needed...then again most reputable shops will keep records.
about disagreeing with dave...i wouldn't say that...i'm just not sure how much you weigh...i'm looking and i think you said over 200? i thought you were like 175/180 or something.

I just spoke with Dave @ GPSuspsensions and he's basically saying that he can do the front for $530 using the components they sell (including new springs). He says his stuff is better than Traxxion (of course he says that) and provided some reasons why. From our conversation, he suggests that my forks may have had some previous work done, but of course won't know until or unless he dissasembles them.

Here's the thing guys, I just don't experince the wallowing and sagging feeling that I should from the bike. Perhaps the front is good or perhaps I'm just that bad, I don't know the difference. I haven't had anyone with specific knowledge to ride the bike (would have been a good idea). I do however have that scary feelings sometimes riding really rough roads. Feels like the bike spends too much time hovering above the ground.
Under hard braking, is the front bottoming? Don't know. How would I find out?

The floating comments sounds like you may have too little rebound in your forks (just my opinion, based on what you are describing).
To find out if the front is bottoming out, place a zip tie on one of your fork tubes, then you can measure how much travel you are actually using, and start keep track of it. If fact you should start a notebook to track you suspesion settings and changes (and other info) and the effects you feel they have. If you don't it's really easy to get lost...

GP suspensions says that they Ohlins guy didn't provide all of the information I needed (I knew something was up with him) and that it's not as simple as saying the stock spring is too low (155-175lb). Dave says the rate is more important. He says that thespring I have may be marginally adequate and it's the minimum # on it that he'd want to see, but he'd have to have some sag #'s to know for sure.
He sounds very professional and sounds like he takes a scientific approach.

So it sounds like you guys are saying that I should go with the modified valve option to save $200 bucks but spring for the new springs. (like that pun huh?)
Dave says that simply porting the stock valves and shimming the stack is still going to allow the suspension to bottom on hard braking. Sounds like you guys disagree.

RE: Re-Springing the Bike
Dan Kyle just called me to discuss my options. He spoke very highly of a few others and warned of a few. This guy knows his stuff and has the professionalism and experience to back it up. I'm waiting on one more reply.
Based on advice here and conversation with Dan, modifiying the stock valves, with a custom shim stack and NEW springsis the way to go on the F4i.
