The manual of course says you need a special wobble wrench from BMC. But that's not the problem, a 7/8 works on the front. But how do you get at the rear sensor?

The manual has a pic of the rear sensor with "...the swingarm lowered for clarity." If you have a good tip, please share.

I dropped or rotated the motor down. Per the manual. Made a great winter project. I however was working on the rear pipe. That was the only way it seemed to work. Good luck.

Finally got it by taking the Torque Hammer and jiffy stand off. Loosen the rear axle and take the belt off. Jack the bike up with an ATV jack and 2X6, with saftey straps to steady the bike. Take the bottom bolt out of the rear shock. Unbolt the brake pedal. Jack the bike up some more. Use a 7/8 crowfoot and long extension to loosen sensor. I'd like to have a 21 mm crowfoot, but they're a special order item in this town.

I had to snip the sensor wire to get it out. It was all wrapped up in this wiring loom and covered with a plastic plate I couldn't get off. The plate's held on with what looks like a recessed 10 mm nut, but there isn't enough clearance to get a 10 mm socket or wrench on it.

The next trick was getting the plug in. It's all slimy from the anti-seize and you're fumbling with a finger from each side. A few swear words and it was in. After that it was a 17 mm socket on a uni and long extension to tighten it up.

Well that was simple....
