All F2 frontends are dual disk and none of them are bad , its just that the 94 F2/F3 front end is adjustable and it also has floating rotors . Functionally , there's not much in it for most people : a well set up stock or F2 frontend is immenently better than an Ohlins unit that is all over the place anyway !
93-95 900RR shocks have a short revervior hose and will add about an inch of ride height . Later model shocks have a longer hose and do not increase ride height . It's going to be necessary to have a spacer machined to make up for the shorter Hawk spring too . Mike Reisch has instructions on how to mod the shock on his page but I can't recall its URL ...
TBR pipes are the worst street pipes for Hawks , they trade a couple peak hp for a big chunk of midrange . That'll be the biggest reason why it'll feel weak after your SV . Richening it up a bit would be the best thing to try , I can't recall exactly what I was running when I had my TBR pipe with UNI's - I want to say 42 pilots , 152 mains and the clips in the middle . I prolly have it written down SOMEWHERE !
I guess I'll add what I've done to my Hawk : F3 forks , 900RR brakes with Nissin 5/8 m/c , bangarang clipions , R1 upper , RC45 seat , Marchesinis,Fox shock, Supertrapp headers with M4 can , 1mm over JE's , 174X8 cams, lots of porting , re-profiled combustion chambers,CFM rearsets,rear brakeline through swingarm , hmm , some other stuff I can't think of .
