Great pic of the open look. I'll go with either a Ballistic, lithium iron or a gel on the battery. It was set up with a massive Sears Diehard because of the electric start.
I just got back from my trip to Alabama. I'm ready to work on it tomorrow. I still have to remove the starter cable, solenoid and a bit of other wiring.
My welding buddy removed the gears by cutting them like a pie. The shaft never gave up the gears. He tossed the gears when he was done.
Here's a paste in from a link out of the CD manual from nfield gear.
"Remove the starter, the primary case outer half, the alternator, the engine sprocket, the clutch and transmission sprocket and the primary case inner half. This entire process is documented and illustrated in section 5 of the Bullet Electra manual and section 3 of the Bullet Service manual which are both available from CMW and everything you need to know will also be found in Pete Snidel’s manual along with tips not found in the other two manuals.
Remove the wire that runs from the starter back to the solenoid in the left hand tool box.
Remove the solenoid.
There will be two wires going to each battery post. One will be heavy gauge and the other a much smaller gauge. Remove the heavy gauge wires as they were only needed to carry the high amperage drawn by the starter.
Drill and tap the bolt holes for the 5sp KS only inner chain case.
Have the starter gear machined off of the engine sprocket.
Attach the primary case inner half.
Replace the clutch and alternator.
Replace the primary case outer half."
