Installation Instructions
MTC 2 STAGE LOCKUP
Your MTC lockup is designed to be installed on top of the pressure plate.
1) If your kit came with new static springs, install those in your modified pressure plate.
2) If you already know how much shim you need to run, if any, install those on the “leg” of the
lockup. If you are unsure, we suggest try using the unit without any shims to begin with.
3) Install your lockup next. Make sure that the lockup bottoms-out (on the legs of the hub)
when the bolts are tightened.
4) Refer to your user guide to adjust the lockup to pressure plate distance.
5) Always check for clearance issues prior to starting up your bike. After starting the bike, it is
smart to take the clutch cover back off and inspect for rubbing or clearance issues.
2 STAGE USER GUIDE
1) The lockup should have .100 - .125” clearance between the flat surface of the arm and the
hardened button installed in the pressure plate. To check this, you can hold the arm parallel
to the button and measure with a feeler gauge. This measurement is controlled by your
clutch pack thickness. You may need to alter the pack thickness to achieve the .100 - .125”
measurement.
2) The static spring pressure controls the first 10-15 feet your bike moves. If you are having
problems on the launch, try changing your static spring pressure. Example, if you spin the
tire instantly or wheelie, take static out. If it seems lazy, add static.
3) If you want to get aggressive with the clutch lever, you will need to soften up your static
pressure. The biggest cause of burnt plates is riding the lever too far. Use the shims in your
lockup kit to increase static spring pressure.
4) Keep equal weight on all the arms. If you add or remove weight, do it to all of the arms.
5) To run a lockup, you will need to run either an air shifter or electric shifter.
6) Should you require any additional support, please feel free to call us or email us at
ClutchSupport@mtceng.com.
If you have a ZX12, this additional section for you.
1) There is an extension for your shift shaft included with your kit. This can be identified as the
aluminum tube 3/8” x 1.5” long, with a hole about 1/2 way through one end.
2) Install this over your existing shift shaft. The shift shaft is in the lower left hand corner of
your clutch case. The shaft will slide on without much effort. Failure to install this part could
result in your bike failing to shift.
3) Refer to additional instructions to properly set your clutch free play.
