I can walk the dog on him just about everywhere in the RPM range. The only time he ever beats me is if we are rolling on the highway in 6th gear and roll on the throttle. His bike seems to react quicker than mine but I always end up catching him if we stay in it.
You know what they say, there is no replacement for displacement. The top drag racers ALWAYS go with bigger motors, that's for a reason.

I'm no qoute wrench but I do my own work.I just did a 107 with 54's I pushed the comp. issue a bit but all good I think if you don't get that to 10:1 or 10:2 it will be a little soft on the bottom end.what I would also consider is the new Andrews 57h do believe it has a 38deg. intake close and would work well with that stock comp 103 and you wouldn't have a problem sellin that 54h.If you want to spend a little on the heads you could get a basic port job for bout 350 or throw in a valve job with maybe a bigger valves for 5 to 6.as far as a tuner I'm gonna catch hell for this but SE race tuner or tts mastertune I think it's called.

I picked up a 49 state 09 FLHT with 26,000 miles and want some more passing power and better fuel mileage. It was stock except for a Dobeck tuner and a bunch of holes drilled in the air filter rear cover? I added a Ness big sucker and SE Fatshots. Which helped alittle powerwise, but not fuel mileage. I picked up a 103 stage 2 kit cheap , Andrews 54h, ARCs and SE compensator I plan to have installed. Anyone run this? My Question is the heads. They will be off and apart for the ARCs so at least a lap, seals and better springs for the cam. I really dont want to spend a lot but if some port cleaning will really help I may spring for it? Im just not sold for my mild build? Also I would like the compression around 9.8- 10 for the cam. What needs to be done for that with the stock heads and cast flat tops? Worth it? As far as a tuner I have no clue??? Im really guessing on everything so looking for thoughts from folks in the know. Thanks

Andrews says to stay under 10-1 and I'd like to stay there? Andrews says the cam is good from 2200-5600. That sounds perfect to me? I really don't have a problem downshifting either. The 57h isn't available til at least mid June I'm told? Lowest port job I've found around here is $500? I haven't heard anything good about the SE tuner from any of the shops around (except HD)?? Don't really like the idea replacing the whole ECU with the tts but it gets good reviews?

Have run Andrews cams before in both 96" and 103", the 54H in the 103" with stock heads and gaskets ran great with PC-V and auto tune, the 96" ran great with the 21H and same tuner. May not be the fastest but mileage was still within 42 mpg and pulled hard. Don't expect 50 mpg unless you are on a test track for EPA.

Call Gary Russell direct at Andrews and talk to him about cams. The 54H does very well at 10.2:1. I'm running that cam at 103"/84.5cc chambers/.030 hg and it tunes nicely. I agree that it could be a bit soft under 10:1 but not terrible. As far as a tuning device, the SEPST/TTS are only as good as the person who tunes it. The TTS may be more user friendly but are you going to tune it? Both the SEPST/TTS use your existing ECU. Check with tuners in your area and get references. The best tuner may very well be at your local H-D shop (mine is) and they can do excellent tunes to your street bike ...
