Suzuki GSX-R1000 (07-11) Ultra Light Clutch Mod Kit
This package contains:
• 1 Brock’s Performance Ultra-Mod
• 1 Brock’s Performance Clutch Pack Spacer (aka: Hyperplate)
• 1 Set (6X) Brock’s Performance Clutch Springs (yellow)
• 1 Set (6X) Brock’s Performance Shim Adjustable Spring Tops
Special note: The terminology used in these instructions correlate
with the Genuine Suzuki GSX-R1000 Service Manual (2007-08 PN:
99500-39310-03E; 2009 PN: 99500-39380-03E). We recommend the
use of this manual for all Brock’s Performance Product installations
and/or maintenance. More Common (Race) Terminology and useful
notes are in parentheses (Example.)
A note before you begin: Assembly is in EXACT reverse order of disassembly, unless otherwise noted. See
Quick Install Guide for more information.
1. Remove clutch cover. The fairing need NOT be removed! It is helpful to remove the rear fairing mounting
screw and gently hold the fairing away from the bike when removing the cover. Use caution-- the cover
gasket is re-useable if undamaged.
2. Loosen locknuts and remove all three clutch lifter adjusting pin screws/washers/locknuts. (These 9 parts
are no longer required)
3. Loosen and remove all 6 clutch springs/tops (These 12 parts are no longer required) and pressure plate.
4. Remove clutch pusher assembly.
5. Loosen clutch sleeve (inner hub) hub nut. (A special tool is available from Suzuki; we use a glove to hold
the inner hub and remove the 30mm nut with an impact gun.)
6. Remove the nut, spring washer and flat washer.
7. Remove the entire inner hub and drive/driven plates (clutch pack) assembly from the countershaft (Input
Shaft). There is no need to remove the outer clutch basket. Also Note: When removing the assembly
from the input shaft, be sure to also remove the parts BEHIND
the inner hub in order. If the assembly does not slide out smoothly, then carefully file the stock “stake
mark” smooth without getting shavings into the engine!
8. The thrust washer (flat washer) may remain on the input shaft.
9. Flip the entire clutch assembly over on a flat surface. CAREFULLY remove the inner hub while allowing
the clutch pack to remain intact, including the spring washer and seat (judder spring and base).

10. Remove the clutch lifter drive cam (back-torque limiter) and TWO of
the FOUR Wave Spring Washers (Belleville Springs). (The two
remaining Belleville Springs will no longer be required.)
11. Install Brocks Ultra-Mod in place of the back-torque limiter with the
remaining TWO Belleville Springs and the innermost spacer ring
remaining in the stock location.
12. Install the inner hub and Ultra-Mod© assembly onto the input shaft.
(The stake mark must be smooth on the shaft and/or threads. DO NOT
FORCE!)
13. Install the flat washer, spring washer and nut. Torque to 68.5 lb-ft.
(The glove and impact gun trick works here also.)
14. Inspect the inner hub for free spin. (If any abnormal drag is felt, STOP
and try the assembly procedures again.)
15. Install the Brocks Performance clutch pack spacer (Hyperplate) before
re-installing the clutch pack assembly EXACTLY as it was removed. (Begin with Hyperplate; add the stock
flat washer and judder spring. If the judder spring continued to form a cone, the point of the cone would
face TOWARDS the engine; next add the innermost stock fiber (with
larger hole) and then a steel plate.)
16. Continue with the assembly until the last fiber plate remains; ROTATE
this LAST fiber ONLY to align with the short slots in the outer basket
(as described in the service manual)
17. Install the clutch pusher assembly. On the (07-08) models, press with
thumb towards engine to offset creep.
18. Install the pressure plate. (Note: The large spline must mesh with the
slot on the inner hub.)
19. Install the yellow clutch springs and shim adjustable spring tops.
Torque to 7.0 lb-ft.
20. On (09-11) models, perform major and minor adjustment (See free
play adjustment sheet.)
21. Install clutch cover/gasket and torque to 7.0 lb-ft.
