im in the marker for a cdi, was looking at a big gun, however i see a ron woods come up on ebay for about the same price. so im wondering which would be the better buy? how do they compair? im a little worried about the ron woods not having a rev limiter? and would a cdi from a 2003 baja work on a normal 2001 ds 650?

 

If you have any reservations at all about missing a shift or the lack of a rev limit then by all means stick with the Big Gun. BG gives youu 1K higher rpm and a slight timing advance.
You will need the CDI with the pigtail for the 01. On the 03 and newer the harness plugs directly in to the CDI.
