This has been the best mod I have made.&nbsp\\; The sound and added pull I am getting makes the bike a blast to ride.&nbsp\\;

With all that motor work suggested, wouldn't it be cheaper to just buy an aftermarket 103 or 110 in. motor?

Unless I'm missing something here, I don't know how it would be cheaper to go with a complete engine change.

I'd look at other cams, not just screaming eagle. Lots of good cams out there other than HD. I just put feuling reaper 543 cams in my stock 103 with stage 1 air cleaner & a thunderheader. My #'s are in my signature.

Do some searching on the net about people having flywheel problems. I have an 06 with a rather well built engine and my motor has beaten a lot of 103's on the dyno.
If you are going to go through all that expense and trouble ,then I would take a look at the new Indian 111 coming out int the fall saw it at Daytona it sounds like it is a bike to ride and not keep throwing money into. Because we all know that what we really want to do is ride,right. don't get me wrong I am Going to be buried w my H-D but they have a few issues that need to be addreeses, All the other top manf. have already done so. H-D seems to be a little slow with progress. Still the only sled I ride

Guess it depends on the "stage" you're going to as much as the "big bore". Assuming you have a 96 and looking to upgrade. I have a '10 fat bob and went with the stage 4 kit out of the 2010 catalog. didn't do any work myself (because i'd surely f* something up). numbers are on the dyno sheet in my pics (roughly 104+ tq/109+ hp). overall, serious improvement, but probably would have been happy w/ stage 2. stage 4 is crazy power but the power band is not in the normal riding range - the low end torque is a bit lacking (doesn't really come on 'til around 2800 RPM), but you can literally "feel" that bike come to life when it does. depends on what you're looking for...

someone else mentioned a whole new motor and argued cost - well, given that i paid labor (not complaining - again, just can't/won't do the work myself), if I had to do it again judging performance against what I paid, I'd have gone with a 120 or maybe another option (http://www.southern-mc.com/smwprseen.html)

I installed my 103 kit on my fxdl, i am an experienced wrencher have rebuilt many a motor. to be honest I was a little intimidated at first to take apart a v twin as it was my first, but once I got into it i found it to be very easy to work on. A few things i would recommend is a lift don't have to have it but it will save your knees torque wrenches, blind hole bearing puller, and a service manual. Also go on You Tube and watch the videos a few times by S&S they will walk You threw the hole thing from removing the gas tank to turning the last bolt very helpful.
