F6K: Factory 6-Speed Kicker



The F6K is the only kicker kit available for 2007 (will fit 2006 Dyna) and later Cruise Drive 6 speed motorcycles.  Bolt on kicker kits are nothing new, but for Factory Cruise Drive bikes they are. The Factory 6 Kicker, or F6K as we call it, use a ratchet hub that presses onto the shank of the mainshaft, then the O.D. of the ratchet hub presses into the oversized door bearing.  The ratchet hub is effectively located and secured from moving by the oversized door bearing.  This can be seen under the images tab in the SolidWorks model cut away image.

Kicker Gears

All BAKER F6K’s come with their own version of the  Klassic Kicker Gears standard. These gears start out of 1018 HR Steel, precision machined and heat treated to 50-55 RC; these gears are tough for long life and tons of kicks.


Section View of Retainer

Mainshaft Retainer
We developed our whole kicker kit around our mainshaft retainer.  Aftermarket kits use a retainer that is part of the ratchet gear that gets threaded on to the mainshaft.  With every kick of your bike this retainer continuously gets tighter on the threads of the mainshaft.  This eventually causes failure and the end of the mainshaft breaks off.  This can be seen in the image to the right.  Our kit uses you a larger diameter mainshaft bearing to house our ratchet gear.  This ratchet gear becomes the support for the mainshaft.   The mainshaft is retained by a nut, just like the factory so no extra stress is put on to the shaft.  Making it the most reliable kit out there.

This tip applies to F5R, F6R, F5K, F6K, RSD and Big Dog style clutch cable installations that utilize a split ferrule for cable retention. It is recommended that the inner cable, ferrule and ball ramps are coated liberally with wheel bearing grease upon final installation. This step has been omitted for photo clarity.

After attaching the clutch cable to the clutch lever, be sure that the cable adjuster is fully collapsed. Screw the cable into the sidecover. Slide the ball ramp over the exposed inner cable, then the split ferrule over the inner cable end. Rotate the ball ramp fully rearward removing all of the slack from the inner cable and engaging the ferrule into the ball ramp. Install a miniature nylon cable tie on the inner wire directly in FRONT of the ball ramp as far back as possible. Snip the excess tie as short as possible. This will prevent the ferrule from accidently becoming dislodged during installation and/or clutch adjustment.

Recommended Fluid / Level
Picking the right transmission fluid ensures the life and durability of your transmission, that’s why BAKER recommends a fully synthetic GL-5 rated gear weight oil of 75W-140. If a GL-5 rated gear lube is not available, these commonly carried viscosities (weights) will work 75W-90, 75W-140 and 85W-140. BAKER does not recommend the use of Syn3 (20W-50).
