It's been a while since I worked on mine but as I recall there are two sizes of primary housings and our Big Dogs used the larger one. Wildsteedworks or Big Dog parts king should be able to fix you up with one. I think you could get one at a Harley shop but I hate recommending that. Good luck!
Well, I replaced my cam sensor on my '02 pro sport,fired right up but when I let go of the throttle, the rpm dropped down to@500. So I'm thinking it is retarded.big dog's manual says I need a special timing module, what's that?
