I have a 2007 XL1200R. I replaced the stock 6R12 Harley Davidson plugs with NGK iridium at 4,747 miles. Wow!! What a difference!The bike used to turn over a few times when starting. Now I just touch the stater and it fires. Smoother idle and smoother at 2,000 to 4,000 rpm

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.

great product; Comes from the factory with them, why use anything else. Had 26,000 miles on original set, no problems. Replaced for maintenance, don't recommend anything else.
