mx tech.com recommends

.48kg/mm Fork springs

5.7kg/mm Shock spring

Stock fork springs are .47 which should be fine, but the rear stock is 5.4kg/mm, so I would start with getting the 5.7 shock spring.

I don't trust the online calculators... do yourself a favor and call a reliable suspension shop.

I made the mistake of trusting the calc, and I am buying stiffer fork springs now because the calculator reccomended to soft of springs. So its costing me $300 instead of $200. Use the calculator, but call a shop to verify the correct rates before you end up buying the wrong springs.

I would call someone and ask what they recommended. From talking to the shop and reading posts, their are different spring rates for what you ride(terrain wise). I ride desert stuff.

precision concepts resprung and revalved my 06 wr450..im loveing what they hooked me up with..getten faster everytime i ride

fork set up..... .48

shock....... 5.8

Get some taller bars and see if you can find some taller bar mounts. Im not sure what you can get for a kawi, maybe a rg3 top clamp with a forward and up bar mount, them clamps are freakin sexy. Im 6'4 and I got the kx high countour bars and im thinking about those clamps too, 5mm taller sounds nice, but the forward actually helps more than up if you ask me, more arm room and it brings you more towards the center of the bike(taller guys tend to be further back on the bike to be comfy)

I've found MX Tech spring calculator pretty accurate, or call Cannon RaceCraft, those guys are the bees knees.

low boy pegs, unless your riding in tons of ruts. tall seat and then the handle bar mods work really well. I also have Leg Pegs on my bike. Since I'm 6'8" i have a hard time gripping with my legs, cause my knees are way over the seat, even with a tall seat, the leg pegs help me grip with my boots and lock me in.
