Installation Instructions for WSBK Timing Chain Adjuster Kit for BMW S1000 RR, HP4, HP4 RACE (2010+, 2015+)
This adjustable timing chain tensioner kit will provide you with a more precise valve timing by removing the inherent excess play of the OEM hydraulic unit. The part allows for a predetermined set chain tension (that can be increased as the chain wears and stretches) giving you optimum cam timing throughout the service life of your chain.
Being fully adjustable and allowing for incremental increases in chain tension as needed, you will alleviate Cylinder 1 valve timing issues resulting from the OEM cantilevered cam chain drive design (cylinder 1 being the farthest from the chain and optimum valve timing). That design allows for excessive harmonics and vibration in an engine that revs at 14,500+ rpm, and sometimes even higher in our fully built and modified race engines.
We highly recommend that this service work be performed at our service facility or an Authorized BMW Motorrad Service Center, otherwise serious damage and/or failure of the engine could result. Always consult the BMW Repair Service Manual CD for you specific model, and have the appropriate tools and compounds required before starting (i.e. – Loctite, etc.)
The essentials you will need are:
- A reliable and calibrated torque wrench that reads in metric Nm
- A vernier caliper (a digital unit is more precise)
- A 24mm socket
- A 14mm deep socket
- Loctite 242 Medium Strength
OK, let's get started.
Turn the crankshaft to top dead center (cylinder 1 and 4).
You can use the BMW Cam Timing Tool available here in our shop.
Step 2. Remove all original timing chain adjuster parts and components, see picture 1.
Step 3. Pre-adjust the timing chain tensioner as shown in picture 2. The head of the threaded thrust pin should protrude about 5mm.
Step 4. Mount the timing chain adjuster housing (24mm) to the cylinder head and tighten it with 30Nm.
Step 5. Turn back the aluminum nut (14mm) by about 3 turns as shown in picture 3, screw in the threaded thrust pin and tighten with 0.6 Nm. Apply some Loctite 242 Medium Strength and counter-tighten the aluminum nut with 20Nm.
You are finished with your installation! Please take a moment and go back through the steps here and check your work.

WSBK Race Mapping Version 2018, BMW S1000 (2010-2018)
Part Number: 1270B580A00-01
WSBK Race Mapping Version 2018, BMW S1000RR (2010-2018), for BMW S 1000 RR/R/XR and HP4, optimized for stock engines with race exhaust system and slick tires.
+ ready to race mapping - know-how of many years of WorldSBK, Superstock 1000 and IDM experience;
+ changes in ECU parameter, no Race Calibration Kit (RCK) data needed;
Race mapping version 2018 including the following optimized functions:
- injection and ignition (optimized torque and power) output (200 real world RWHP or 220+ HP at the Crank) vs. 181 RWHP stock on BMW S1000 RR.
- traction-control by selective cylinder fade-out (CUT's) full gear-dependent, wheelie-control (GDTC+)
- quick shifter (reduced shift duration + V3 Fast Shift Sensor option)
- engine rpm limitation with soft-cut interruption
- launch control in first 3 gears- WSBK level engine braking- deactivated exhaust servo valves- deactivated O2 lambda sensors (race fuel compliant)- deactivated both knock sensors- deactivated secondary air system (must use our SAS block off plates)- fuel >= 98ROZ and MR12 now possible. Note:- Slick MODE plug required (available in our SHOP);- Race-setups are rider dependent. For final adjustments the option "ADD ON+ Race Calibration Kit 3 (RCK3) with race mapping" or a custom option is recommended (available in our SHOP too); Please note:We need to have the ECU only (on 2010-2020) bikes to install the mapping correctly.
- e-throttle optimization (independent in riding modes)
