I have not tried one 'yet', but have read of many riders using the "Gold Valve" cartridge emulator with great success..

2008 DL650 VStrom Yellow and Black
Previous ride was a 2007 KLR Black/Silver, I miss it..
Looking to get back into KLR's sometime soon.

RaceTech GoldValve Cartridge Emulators

Oh yeah!! you wil like it.
follow the directions carefully.
when you drill out the compression holes in the damper rods, be sure to get the flashing particles trimmed out of the backside of each hole you drill/enlarge all trimmed off. Otherwise they can get loose later and float around scarring things as they get between moving parts.
You tune the rebound speed with oil viscosity (I think we ended up with 20w in mine),
The directions will say to start with 15w. this is okay if you want bouncy, free moving rebound, great for off road, but too loose for fast pavement riding. I like it planted in fast turns on pavement, and it's still pretty good in the rough. All forks seal differently, so the generic directions are a starting point to tune from.
tune the compression resistance by adjusting the emulator spring ( I have 4 turns of tension on mine) That's a bit tight but I like the dive control.
It lets me use the front brake very hard and late if need be and settles nicely.
Since my weight is only 170 lbs I have stayed on stock springs so far.
I am going to go up in rate a bit, but I will use lightly preloaded STRAIGHT rate springs, not a progressive wind.
If you would like, you are welcome to hit me with any other questions. I have installed hundreds of these upgrades, several a week since 1996.
In back to back testing we have found the RaceTech GoldValve Cartridge Emulators to be better than the imitators. More plush on bumps, as much (adjustable) compression damping as you want.
More plush on bumps, both are better on compression dive.
When you are ready, upgrade the rear with a GoldValve kit too.
Together they improve the ride quality and feel to a level that doesn't come with really expensive bikes. ( they need the same things)
Emulators (properly installed) lift the performance of damper rod forks beyond the level of stock cartridge forks. Cartridges can be made that much better, but you have to go into them and upgrade.
anyway, good luck with your install.
Feel free to contact me if you have questions.

Thanks for offering to ask questions. I have a new to me 09 KLR and weight 220 w/o gear and 245 with gear. I'm a solid B class rider and ride the bike pretty hard. Naturally the suspension is lacking In technology and adjustability. Loaded with panniers and trunk bag the darn thing is a wobble warhead, it rideable but an effort to get the bike to turn where you want it and at speed in the rough stuff is sketchy.
So this is what I am thinking of doing. Let me know if I am on the right track and i have a question for a few of the mods
1. EM Fork Braces
2. Larry Roseler progressive springs
I have read that spacers are used in the 08 and later. Wil these be reused with
progressive spring mod? I installed a 1" PVC spacer that i intend on removing that is
below the cap and top of spring to get a little more ground clearance along with the
shorter shock linkage brackets.
3. Race Tech damping rod emulators
What's a good base setting for the emulators considering my weight, base oil wt and oil
height , I was thinking 5-6 turns on the emulators and 20wt @ 150mm.

Thanks in advance for your input.
