Installation Instructions Hymec F 800 Models
Thank you for purchasing this MAGURA product – we hope that you enjoy using it.
MAGURA recommends that you arrange the fitment of this product with a suitably
qualified motorcycle technician. This fitment instruction provides a guideline for the
fitment of a Hymec on a BMW 800cc Parallel Twin. Due to the different models
available and changes to individual parts during the model lifecycle – we cannot
ensure the accuracy for every model or production year. Before you begin with the
Hymec installation place the motorcycle upright on the main stand or paddock stand and secure it.
Required Tooling and Parts
Torx T25 / T27
Fork / Open-end Spanner – 8 / 13 / 17 (2x) / 19 mm
Adjustable joint pliers Small flathead screwdriver
Cable cutter Cable (Zip) Ties (2x)
1)
Remove the seat unit.
2) Remove the centre trim panel (disconnect on board socket) and left hand side panel.
3) Remove the battery negative terminal connector.
4) Remove the intake air silencer.
5) Remove the clutch cable at the engine by loosening the securing nuts, disengaging the cable from the release lever and then
removing the cable from the support on the engine cover.
6) Remove the clutch cable from the handlebar fitting and disengage the cable securing brackets.
7) Remove the clutch return spring under the clutch cover – see separate instructions No.2. The Hymec will operate without the
removal of the return spring but will require a larger hand lever setting to separate the clutch as the first 25% of the slave cylinder
operational travel will be used to negate the clutch return spring effect. To fully appreciate this product MAGURA recommend that
you arrange the removal of this spring with your BMW Motorrad Dealer or suitably qualified motorcycle technician.
8) Remove the mirror from the handlebar clutch fitting and disengage the clutch switch connector.
9) Remove the handlebar clutch fitting and replace with the MAGURA 167 clutch master cylinder from your Hymec kit.
10) Route the clutch slave cylinder and pressure line along the same route as the clutch cable while carefully removing the clutch cable.
11) Install the Hymec clutch slave cylinder being careful not to bend or damage the activation arm. Note - do not pull or push the
activation rod.
12) Install the Hymec slave cylinder by inserting the slave cylinder into the support on the engine cover and then into the clutch release
lever.
13) Adjust the slave cylinder free-play with the locknut adjuster provided to a value of 4–6 mm.
14) Activate the clutch master cylinder and ensure that the Hymec is operating correctly.
15) Using cable (zip) ties fix the pressure line in position ensuring that it is free to move regardless of the positioning of the handlebar.
Use the original cable securing brackets at the top near the master cylinder which were previously securing the cable.
16) Reattach the mirror and clutch switch connector at the master cylinder and position the lever to your desired slant.
17) Reinstall the intake air silencer, battery, left hand side panel and seat unit.
18) Check the clutch activation to ensure that it separates fully – Adjust the master cylinder lever reach adjust until the pressure point
and separation point are suitable for your riding style. See Hymec manual – chapter 4 – CHECKING THE INSTALLATION.
Hint: If the lever is adjusted fully inwards it may prove difficult when the engine is running to shift from 1
st or 2 nd gear into neutral. This is
because the clutch is not separating fully and can be improved by adjusting the clutch lever slightly further outwards to increase the
Hymec clutch travel or by decreasing the free-play at the slave cylinder to 4 mm. A free-play value of less that 3 mm can lead to
clutch drag when the clutch heats to operational temperature and should be avoided at all cost.
This product has been lifetime filled and if properly installed with the correct free-play value will automatically adjust for clutch wear or
expansion ensuring a constant pressure point and improved feel and modulation. Please enjoy the product and ride safely at all times.
If the clutch return spring is not removed from the inside engine cover the Hymec will operate but not effectively as the first 5mm of
clutch travel are used to take up the travel from the return spring. After repeatedly activating the clutch the pressure point may wander
as the slave cylinder will not fully return to its starting position. The full hydraulic clutch effect with constant pressure point will only be
achieved if the clutch activation lever return spring is removed – see separate instructions.
