dialing in the stock rear shock

<< < (2/3) > >>

ShanMan:
:shock: Awesome replies! Thanks to every one of you (in particular Rick for taking the time to write a how-to article) for the knowledgeable words. I hope one day to be able to pass it on myself. I am a moderator of a vintage Mustang website myself. Maybe one day you guys will have a question about classic car restoration, and I can be of some help. In the mean time, I will get home tonight and get the rear shock set up as best as possible for this weekend. Again, my thanks!  :)

HULKSTER:
Yep....that's good info....I'm going outside now and starting on the 500 I just got....great thread.

John:
Hi all,

Is there anyone out there who actually knows how the race sag is calculated on a bike? My guess would be a ratio of some variables probably including the full stroke of the suspension and the spring characteristics. On all the bikes I've had the race sag is more or less the same? Could be that I am only adjusting the race sage on my MX bikes - duh.

I?m just curious.

BTW. I found this information on the net (locking for formulas) with pictures and all, see 4 strokes??. The principle is the same for 2 strokers  :wink:

Another BTW. Don't buy one of these expensive tools to adjust your spring pre-load. Use a blunt screwdriver and a hammer. There is not a lot of space around the spring.

Paul:
Thanks for that link John, thats good information there

teamgreen500:
At one time, I must admit...Oh the shame :cry: ...I was at a Showa (Honda) test session and I heard the ratios being discussed. It was 3:1...Travel:Sag-loaded. This is actually the basis for determining correct spring values. This was many moons ago and in a Galaxy far, far way...I'm so ashamed...wait a tick :roll: ...this WAS in the day of David Bailey...Hmmmmppphh...Its cool! :lol:

I might suggest that a person might find it very educating to, one at a time, try testing his bike with FULL light and then FULL hard COMPRESSION and then find where the settings seem to be best.

Then, do the same on REBOUND...HOWEVER, It's REBOUND  :!:  :!:  :!: that can REALLLLY hurt you! SO BE CAREFUL! If you do this and experiment with it, you'll discover why these adjustments exist and you'll also find out why some of us actually adjust our suspension during long/multi-terrain events (shhhhh...that's a secret!).

Best of Luck and Care,

Manny
