g’day guys at tekniks !
before i start, you guys have done work on our bikes a couple of years ago ( 83 XR350 and 85 XR250 rear shocks ) and we couldnt be happier
now days i got a 2011 CRF450x and im getting into pony express’s ( well actually the iron man side of things )
i havnt touched the suspension since i got the bike brand new except changing the oil in the front forks, and raising the front forks about 3-4mm in the tripple clamp
as i really got no idea where to start, after riding the CRF for 4 hours straight on braking bumps, hills rocks etc my shoulders and back copped a caining and was wondering what you guys can sugest to do ? i can get the suspension to you guys no problem or if you would rather the entire bike there that can be done, i just want the bike set up right so i can be more competative with the guys that have all the trick bits suspension wise
im 90kg i thought this would help too 
cheers nathan
