Could someone clarify the terms "compression" and "rebound" as directly related to the rear shock on a '97 M2 Cyclone | ||

Because 'pull' shocks (as used on tuber Buells and Softail Harley's) reverse suspension loads introduced to the damper, the terms are opposite of what they are for a conventional shock. Compression damping occurs when the shock gets pulled and gets longer... meaning when the rear wheel moves up in its range of motion. Rebound damping occurs when the shock gets shorter... when the rear wheel moves back down. Is that what you wanted to know? | ||

Yes,that is the way I understand it to be.Now this weekend I disassembled the rear shock,as far as removing the "can" and spring.With shock in a vise I adjusted the "comp." and "rebound" as per described in service bulletin B-024(recalled shock installed) and it seems as though the "comp" adjustment screw,on the shock eye(closest to swingarm)affects what you just described as the rebound stroke of the shock(shock getting shorter) and the rebound adjuster on reservoir affects what we think is the comp. stroke(shock getting longer),as it would act on a conventional shock.With this said,what is a pull shock?Is it a conv. shock with modified spring attachment to load spring when the shock is "pulled" on our bikes,or is it actually a shock that is manufactured with valving "reversed" as to be the comp. stroke as shock is pulled(elongated)Its beyond me how one would ever get the suspension adjusted properly when the said comp.adjuster affects what is in reality the rebound stroke of our suspension.Are you totally confused now or does any of this make since ? Sorry to be so long. | ||

I'm really not understanding your question. If you have a Showa cannister shock, the compression damping adjustment is one near the rear shock eye; the rebound adjusment is on the reservoir. You seem to be describing the opposite when you made changes to these damping adjustments on your shock. | ||

Yes,a Showa cannister shock,the compression adjustment screw at the rear shock eye does not affect the compression stroke of the shock,it affects the rebound stroke.To verify this I will have the shock put on a shock dyno.I do not see any markings on the shock that indicate a part number or model number,but it is a Showa can. shock | ||

when I got my recall shock installed I asked for info on adjusting the shock, the dealer took a photo copy of the "98 S1 showa shock adj. from the owners manual.It shows the rebound at the back of the shock and the compresson adj.on the canister,(remote resevoir). | ||

Thanks Saxon59.When I visited my Buell Dealer,I was given a copy of Service Bulletin B-024 Safety Recall Code 0817-Shock Eye as noted,correct application for shock installed on my bike.For future ref. I would like to have a copy of said shock adj.,if at all possible.Unable to post SB B-024 due to size of file. (Message edited by MBC on October 12, 2008) | ||

Mbc,I'm kinda low tech,I don't have any way of posting it,but,if you have a fax # I'd be happy to fax a copy. |
