The CDI is a very simple swap, just take off the gas tank and two mounting bolts later it's out. When mine went out, I was relieved to find the problem, but at the same time depressed when I knew what it would cost, $550. That's a lot of dinero for an igniter box. Sure wish Procom would get on with it and put one out there for our bikes. And that's the problem with our bikes compared to Harleys. Something breaks on ours and we're usually at the mercy of expensive OEM replacments. Own a Harley and you can find much cheaper replacements. Just check this ebay auction for a Harley Dyna CDI box that sold for $31 plus $10 shipping. The price we pay for having an exclusive bike.
