ZXR750H2 stock suspension settings

[car]

Suspension's a bit tired on my H2 which, with delicious irony, makes it a fairly comfortable ride. The front is as hard as I remember, but the rear sags a mile, and it squats and understeers when making progress through corners.

I've upped the preload slightly on the rear and dropped a little on the front, and it feels like it's sagging equally now.

:)

I'm a little wary of messing with the preload too much, though, given that my oil's probably 60,000k old. Obviously, rebuilds or replacements are probably in order, but in the interim, if you've got any tips, or know the stock setup, I'd appreciate a pointer.

Cheers,

Chris.

The only hope you have of making that shock better is getting a rebuild done on it. I had my one from my 89 ZXR750 done by Bruin Engineering, and it came back better than a new stock shock!

As Sugi said get the damper rebuilt & sling a after-market spring in :yes:

Here's the suspension setting as per the book:

Front Forks
Fork oil type ............. SAE 5W
Fork oil Level............. 135+/- 2mm
Fork oil capacity.... Dry Fill(overhaul) 445+/- 4cc,Oil Change 380cc

Suspension Adjustments

Fork rebound damping
Standard........ Fourth click
Hardest..........Fully Clockwise
Softest...........Fully counterclockwise (anti-clockwise = 13th click)

Front fork spring preload (adjuster protrusion)
Standard.......16mm - 6.5spaces
Hardest setting......... 5mm - 1space
Softest setting.........20mm - 8-1/2 spaces

Rear shock absorber rebound damping
Standard setting.......II
Softest setting.........I
Hardest setting........IIII

Rear shock absorber spring preload
Standard setting.........10mm less than free length
Softest setting...........6mm less than free length
Hardest setting...........26mm less than free length

and there's a ride height adjuster cam on the bottom linkage where the tie-rods bolt on :dodge: aye Sugilite:bleh:

Thanks, both of you. I'll squirrel that phone number away for when I've got readies to spare. I think the first thing on my list, (after a paddock stand,) should be a manual, though.

:)

Why, oh, why did I throw out my Haynes manuals before coming over here?
