The TX650 came stock with an electro magnet alternator, a popular mod is a PMA using second hand parts from various bikes and bodging up a Banshee mount to fit. Otherwise you can buy a new conversion kit from many of the XS specialists.
I baulked at the price of the kit, around $400/$500. I also didn't fancy using 40 odd years old parts and a bodged up mount.
I found new parts on ebay: a stator ($50) and reg/rec ($25) for an XV, and rotor for a Banshee ($60) for an all up cost of $135. Using a slab of ally I had lying around in the shop I spun up a mount to fit the stator to the TX. I didn't have a piece of ally the right thickness (45mm), so made the mount in two pieces.
The keyway on the TX crank and rotor is 5mm, whereas the keyway on the Banshee rotor is 6mm so I had to step a woodruff down to fit. I then found the diameter of the woodruff was too big, so the woodruff didn't fit all that well, so I turned up a piece of stock to the correct diameter, sliced it in half, stepped it and shaved it down until it fit.
Timing is normally done on the TX using the alternator rotor which has marks on it, the new Banshee rotor doesn't have these marks, so I refitted the original rotor, timed the engine, removed the original rotor, refitted the Banshee rotor, made and fitted a pointer plate and marked the pointer plate and rotor accordingly.
To make the lekrisity flow better I polished the mount. The experts should appreciate that one.
The reg/rec was mounted on an ally plate behind the battery carrier.
