Installed ok, good voltage, everything seemed fine for about a year. GSXR died one day, took it apart to find out why, and the connector from the stator to the brand new Rick's Motorsports regulator/reticfier had caught fire and disconnected.
Emailed Ricks, and they told me the warranty was one year (I purchased 7/14/14, caught fire 9/3/15) and I'd be at the mercy of the retailer thru which I bought it (this site)for a warranty claim. They then recommended I buy a $20 "heavy duty" connection kit to replace the fried connectors.
I don't think I'll be giving Rick's any more of my money. Recommend avoiding this product.
I'm an e3 fan. however, matching these to bike didn't tell me that I'd need a non-standard plug socket. Now I must figure out how to deal with that since it is not "for the bike" sized. Also, no mention that I'd have to de-thread the "car" plug wire socket so it would fit on the bike.
While I love the e3 stuff, and the bike after 1/2 tank seems to like the plugs, these were not the drop and swap that were advertised. Plug wire caps required vice grips to remove (x 6 plugs) and it took a bit to figure out that metric sockets were not going to cut it for this.
Better comments, packaging and socket sizing would be good if you are going to "right size"
