Hayabusa Rear Shock questions

[BarMatt80]

Well i just got my hayabusa rear shock to put on the bike once i get some more parts, and man this thing is big. Bigger than expected. THe meaurement from center of bolt holes is 12.875". I am sort of suspension dumb, so I am wondering what the top adjuster does and the bottom adjuster. DOn't have ot get specific i can read the all about suspension or whatever forum, just don't know what is for what. Thanks guys.

Shock:


Top Adjuster


Lower Adjuster


on the adjusters it does not seem to have a limit number of turns you can adjust with the exception of in, where the adjuster will bottom out.

Found this. Hope it helps. I'm guessing you know what the preload is....

Rebound adjustment (if applicable) is located at the bottom of the shock. Compression adjustment (if applicable) is located on the reservoir. Spring prelude is located at the top of the shock.

Shock: Lack of Rebound

Symptoms:

• The ride will feel soft or vague and as speed increases, the rear end will want to wallow and/or weave over bumpy surfaces and traction suffers.

• Loss of traction will cause rear end to pogo or chatter due to shock returning too fast on exiting a corner.

Solution: Insufficient rebound - Increase rebound until wallowing and weaving disappears and control and traction are optimized.

Shock: Too Much Rebound

Symptoms:

• Ride is harsh, suspension control is limited and traction is lost.

• Rear end will pack in, forcing the bike wide in corners, due to rear squat. It will slow steering because front end is riding high.

• When rear end packs in, tires generally will overheat and will skip over bumps.

• When chopping throttle, rear end will tend to skip or hop on entries.

Solution: Too much rebound. Decrease rebound "gradually" until harsh ride is gone and traction is regained. Decrease rebound to keep rear end from packing.

Shock: Lack of Compression

Symptoms:

• The bike will not turn in entering a turn.

• With bottoming, control and traction are lost.

• With excessive rear end squat, when accelerating out of corners, the bike will tend to steer wide.

Solution: Insufficient compression. Increase compression "gradually until traction and control is optimized and/or excessive rear end squat is gone.

Shock: Too Much Compression

Symptoms:

• Ride is harsh, but not as bad as too much rebound. As speed increases, so does harshness.

• There is very little rear end squat. This will cause loss of traction/sliding. Tire will overheat.

• Rear end will want to kick when going over medium to large bumps.

Solution: Decrease compression until harshness is gone. Decrease compression until sliding stops and traction is regained.

thanks steve, i'll have to learn somethings for it, and what you found will be great on setting the bike up. that is something have needed to do for sometime.
