I'm looking at selling this combo fairly soon. I'm currently running it in one of my bike with no issues.
with a new battery it was reading 12.9 at idle with the wire mod to the positive terminal reading 13.5ish.
it is a bolt in but you will have to add the connectors on the stator wires. The good thing is, the wires are cut so that can slide through the factory grommet. The wire diameter is a tad thicker than stock so it takes a trick to get them through the grommet.
you will need to use the factory connector from your bike.
I'd like to keep this price under $100. for the set. probably free shipping in the US.
After I get a few miles under my belt I might donate a set for feed back and test purposes....
