whiplash433 Posted April 12, 2010 Next time i go to the track i plan on doing some fine tuning with the rebound and compression but i dont know what to look for on adjustments. What i want to know is if my bike is doing x then i have to do y? Any help is appreciated. Thanks 👍 Share this post Link to post Share on other sites
Dexter643 Posted April 12, 2010 (edited) I came across this flowchart a few years ago. It's from a street bike point of view but most of the premises cross over to dirt. The following notes/addendum were made by a local suspension tuner: ********************************************************* Wont' turn in: Fork changes make sense, but geometry and tire size/compound not mentioned Excessive Dive: Preload and compression changes make sense, but no mention of changing rebound to match preload, nor is there any mention of oil level or condition of oil Front pushes/trail braking number one cause is geometry and tire size/compound. Preload and compression changes are fine but no mention of changing rebound to match preload. Shock rebound may work but that is a long shot and will open another can of worms in this case. Front pushes/throttle: compression and preload changes are okay, but must match rebound to preload Chatter/trail braking rebound could be a source, but unlikely. most time due to low oil level or high oil level, or too much or too little preload and/or compression Chatter/throttle rebound for chassis imbalance front and rear, shock compression, or geometry WALLOW - shock only CHATTER - fork only Exiting/chatter/holds line generally fork or shock rebound creating instability Exiting/chatter/turns well correct on geometry but if no front tire tearing, leave it alone. Remove rear ride height only if tire tears Exiting/wallow/won't hold line soft shock so add compression and/or preload, then check rebound setting ********************************************************* And one thing I'll add; in addition to tire size, tread pattern, wear, and compound, inflation pressure (PSI) can have quite an effect on handling and 'feel'. To me, 15psi vs. 12psi is as noticeable as a few clicks of compression adjustment. Edited April 12, 2010 by Dexter643 PSI info Share this post Link to post Share on other sites
