If you search the forum, you will find that people think that this (110) upgrade is less stellar than you would think. If memory serves me correctly, with the 103 SE installation (255 cams) you will come close to the 110 at more than $1000 less. When I was working on analyzing which upgrade to do last Summer, that's what I found. If you want to spend the money on the 110, you should consider other non-Harley options. Again, do a search and you should be able to read people's experiences.
