Got the 203's in my bike, mostly because they were a leftover from a big bore kit I got cheap, but never installed on my old Wide Glide 'cause I traded it off for the Ultra. I can smoke my buddies RKC with PCIII, stage one and slip ons. Last Dyno run was right after the Bub7, SE air and the cams were put in, and it was 85 HP and 91 TQ. Probably losing something because I didn't go 2-1. It's adequate for me and the little lady for now, 'cause we can get out of our own way when we need to. Probably gonna change the whole thing next year, year and a half, and go to a 107 HQ build for more all-around grunt.

OK so . . . to the next level now. Leaving the 203's in, so as not to interupt this thread (this is actually a good one) . . .
What can I (really) expect bumping up to 95" ? I know it's not as much of a jump as going 883 - 1200 (simple math) We did that with my wife's 93 Sportster (when she had it -- damn I miss that bike!) But holy moly what a difference !! Wow !!
I was also considering going to a 34T pulley (32 is stock?) so as to raise the final drive ratio w/o the expense of a 6 sp.
Really just wondering about best bang for the buck options.
I'm thinking 95" , mild head work? Mikuni 42?

If my memory is correct (it's been about 9 years), I got 78 hp and 86 lbft torque. When I say it ran great I mean it was very smooth from just off idle to about 5000 rpm. Cams run out of gas right at 5000. In my opinion porting and/or polishing heads with these cams gains you nothing. Stock heads including the pre-06s have plenty of flow for the lift/duration.

I don't get it are you trying to justify a bad cam choice. It's doesn't seem like you are get much of a positive responce here.
I'm not giving you crap, heaven knows I have wasted so much money buying the wrong crap over the years.

Why can't a person want to get the most out of what they have already in their bike?Hell if it was just all about speed all i would have to do is put a turbo on my bike and never have to worry about another upgrade.I just want to keep my cam that i am happy with and see what is the best set up i can come up with that will let me have the most i can out of it.Hey different people go about what they do with their bikes and they can do that because they paid for it,right.

Mark, I "think" what Phil is trying to say is that it appears a decision has been made to optimize a setup with the only given choice being 203 cams. If this is trure then you only need a 2-1 exhaust, high flow breather, and tuning. Differences in all the pipes and filters available won't make much if any difference with the very mild 203 cams. I ran the 203s 10 years ago because they were the only ones available when the twin cam came out. Honestly, there isn't very much difference between them and stock. 203 cams aren't in the ball park when you are looking at bang for the buck... That's why all the comments on here about the cams. I've learned over the years to base my build 1. what I can afford. 2nd on the parts to get the best reliability and tq/hp in rpm range I want. The best all round combo I ever ran was a 95in twin cam with S&S 570 cams. It made 96 hp/106 lbft. I put over 50K on that setup with NO issues at all. Unfortunately I'm a power junky and always want more and the latest and greatest.

exactly.... It's no different than if the OP had said, help me optimize my setup, and I am not gonna change cams. Bang for the buck is the same.
