New Battery

I just purchased a WestCo Battery from BeemerBoneYard on sale for $89.95.  This battery is highly recommended right behind the Odyssey PC680, which costs around $130.

This battery slides in without any fuss, and uses standard chargers, so I'm good to go.

I decided to put a label on the side facing the tupperware, in case I forget when I replaced it, I wish the previous owner had done this when the previous battery was replaced.  I did not know the age of the BMW Exide battery that was in the bike, but I was getting many ABS faults, which is a tell tale sign of a weak battery.

I proceeded to remove the snorkel air intake tube, disconnected old battery, and slide out and put new one in, took about 10 mins, easy as pie.

Here is the finished product, all buttoned up and labeled, the battery strap was a bit loose, since the new battery is not as tall, I put a sponge in there to fill the area.

Carb Sync

I received my used "TwinMax" in the mail yesterday.  The BMW mechanic sold me a TecMate CarbMate electronic carb synchronizer which is the same as the MotionPro Twinmax.  I warmed up the bike for a 10 mile ride, then came back to sync idle.  Cylmers says it should be between 1050-1150 rpm's.  Mine was running a bit high, probably 1100-1200.

I zero-ed out the tool at the lowest setting, then hooked it up to the vacuum ports on the throttle bodies.  I then turned the sensitivity up to 2.  I turned the BIG BRASS CREWS in all the way then backed each out to 1 1/4 turns.  I proceeded to set the idle at 1050 and sync the idle at the highest sensitivity setting on the CarbMate which is 0,5 of Mercury resolution, slowly turned the right screw until a Happy Face green LED showed solid bright light.

After idle I slowly turned the throttle and the green light never wandered at higher rpm's so I left the throttle cables alone, and took a test drive.  I noticed the vibration in the mirrors was less and the idle felt less rough.

I like this tool, look forward to trying it out on the Airhead.

New Rear Brake Pads

Changed the rear brake pads, 51K, rear outside pad measured less than 1mm thick.  Purchase new Carbone Lorraine pads for the rear.
