As I couldn't stand the thought of paying $11 for a bolt with a magnet in the tip of it and I got a steal on a sensor for the Vapor on eBay for $11, I was determined to cheap out again. I chucked up a good flanged M6 bolt on the lathe and drilled out the head to accept a tiny neodymium magnet I stole off of one on the refrigerator. Then I machined a top hat collar to mimic the factory rotor bolt and put it together:
Then I drilled and bolted the sensor itself to the caliper bracket. Heat shrink over the connector and routed it all along the path of the brake line:
Programmed the wheel size into the vapor using their formula and I'll be danged if it didn't work!
Aside from the kill switch (discovered that even with the battery completely disconnected the bike will run...this is a good thing!) and a tag bracket she is ready to rock and roll!
