Raising the forks

Hello,

I very recently purchased a 2005 DL650. So far I am very happy! I have discovered, however, that the front end feels a little light. I did some searching and found that raising the rear spring preload and raising the forks in the triple tree helps. I do want to get better feel from the front end riding on the street, but I don't want to loose too much ground clearance for the dirt. I have read that the forks should be raised 15-20mm. In the interest of clearance, is 10mm a better compromise? Please, share any and all opinions. While I'm here, I'm about 150lbs...where about should fork spring preload be?
Thanks!

I initially raised my fork tubes about 20mm, but found the bike really wanted to "fall in" to corners.
I have settled on 8mm, and find it just right for me.
You might want to consider a set of SonicSprings for the front end as well, it makes an incredible difference for not a lot of coin.

I also made a 3mm spacer for the rear spring, as I found I could not dial in quite enough preload when the bike was fully loaded for touring. I do like a fairly stiff rear-end (I'm talkin bikes here... ) for more spirited handling.

Try Rich at www.sonicsprings.com to get you set up, you will find him most helpful.

Cheers!

Try 10mm first. I wouldn't go any more than 15mm, as after that you run the risk of the fork sliders hitting the lower triple.
Use preload to set your sag, 40mm is a good number to shoot for on the Stroms. We have a write-up on that procedure at:

Let me know if you have any other questions.

Hey Rich and rcacs,

Thanks for the info and suggestions. The plan is to make those adjustments today. Rich, if I'm looking for springs in the future, I will definitely consider Sonic Springs. Thanks again!
