se255 is my preference you will be happy with them... I have installed dozens of them on customers bikes and all are happy.
What's the difference between the 255,s and the 253's?

The intake close alone is enough to make a major difference in the low-end without increasing compression. IMO the 253's would be a poor choice if low-end TQ was a priority and stock compression was used.

If I read that right, he not only changed cams and exhaust, he made other changes as well? If so, I don't think it is a fair compairison.
I personally ride an Ultra and almost always go over 4,000 rpm just getting up to speed to merge on the freeway.
I see little practical difference. The headwork was the same, which I think would benefit the 6-6's more than the 255's since they are a peakier grind and the headwork will benefit higher RPM's more than lower. I would think it would likely hurt the low-end overall. The difference between Jackpot mufflers with stock head pipes vs. MO's with the Power Duals would not be clear to me, although I tend to think of the Jackpots as being the best-performing slip-ons available, all other factors being equal. They are not equal with the addition of the PD's, but I can't say how the two exhaust setups compare on the dyno.

Not trying to get into a debate on cams I'm no expert, but everything is a comprimise. Overall, from my personal experience and from the posters comments, seems that the Woods cam gives more grunt overall.
They do, but were likely not as strong in the extreme low-end and in the OP's opinion did not provide any performance increase "where he rides." It's all where you want the power to come in, and the 6-6's would clearly be best if top-end power was your goal. Keep in mind also that the 6-6 and 4° combo would've cost me $525 vs. $110 for the 255's. That coupled with my desire to increase low-end and midrange and the decision was a no-brainer, for me.

OBTW aren't the woods cams 380.00 retail? + 15.00 for a plus 4 key from T- Man?
I was quoted $400 for the cams and $125 for the gear plus shipping, but I would think an Andrews gear would work as well and is cheaper. FWIW the 6-6 + 4° gear was my second choice, and this combo lost out because of cost and based on dyno charts I saw the 6-6's would have decreased the extreme low-end somewhat when keeping stock compression. I was determined that at no point in the low-end would a TQ decrease be acceptable, and that alone eliminated the chances of every other cam available as far as I could determine.

Wupps....I was thinking about 203's wasn't I? Isn't that the cam that used to come with the 103 kits? Of course I could still be wrong on that. I can never find the specs for the SE cams.....where did you run across them ICLICK?

Cool!! Thanks Barrenmug! Huh...guess they actually made the 255's a bit bigger lift and different duration than the 203's learn something new everyday! That is a pretty good list of cam specs. LOL now I can do some comparing when I get bored.

You can download the HD SE catalog here. The cam specs are on p.43.
