    I am going to install a smaller battery to replace the brick sitting behind my airbox. I was wondering of anyone knows of another grounding point or method other than down by the speedo cable, see picture.

    Thanks!

    Why? My speedo bolt has the case threads stripped out. So i moved it over to the allen head bolt next to it. Got a steel spacer about .5" long and a longer bolt from the local hardware and bolted to the trans case. 9" #6 ground strap.
    Thanks Plaka!

    I mount to a transmission cover screw. I used an aluminum chainwheel spacer (bicycle shop) and a slightly longer bolt. Went on the cover screw just above the current location. This puts the mounting point just a bit under the edge of the battery box but I always disconnect at the battery with a one tool copper lug.

    As above - I got all fancy and got an M6 stud and a serrated flange nut to bolt the cable to the case.

    I use an M6 coupling nut. First I cinch down the cover with the nut and washer as per usual, then I use another short M6 bolt to fix the cable to the coupling nut.

    I fasten mine to the rear right side coil bolt across from the main chassis ground
