Moto Pro
FYI, Moto Pro had springs for my '06 a few months ago, but he did have them on order. They made a tremendous difference in the handling department. The nose no longer dives while braking and the whole bike just handles more precisely. Great on single track now.

A good investment is the Race Tech's Motorcycle Suspension Bible. Almost 300 pages of motorcycle suspension information - very informative. I picked mine up for about $25 off Amazon.

Are you sure RT has optional fork springs? The reason I ask is that their site doesn't show any alternate springs. They list a recommendation as far as the weight of the spring, but they show no alternate choices...kind of strange. If you check for rear springs, they show several alternates. I'm just curious. I used RT fork springs, but I have an '06 which will use KLX300 with no problem. I know for sure that John at Moto Pro has '09 and later fork springs, with alternate weights.

Replacement springs
This is a little late for this thread, but maybe 'Sticky' worthy.
You can get new springs directly from the 'spring makers' that many of the suspension tuners get theirs from:
Home - Cannon Racecraft
They make them to order, so it may take a few weeks.
Ride on,

Racetech's and MotoPro's suggested spring weight for me used to vary (.44 vs .46), but I think it depended on what riding style I selected. I'm sure if you're getting a lot of air you need stiffer springs.

I'm around 180 lbs and was getting .42 - .46 as suggestions. I'll probably end up going with .46 so I have wiggle room with packing up bike, taking it on bigger jumps, etc.

springs
The company I put the link to makes the springs for MP. They were $119.00 for front or rear...plus shipping. The KYB shock for the KLX uses a two diameter spring, and are made to order. I did both ends, and it was just under $250 to my door.
