Advice on 103" Build!!!!!!
What's up guys?.......I getting ready to have my 2010 Fatboy Lo bumped up from 96" to 103". My Tech wants to order me the 103" jugs, High comp forged pistons at (10.5:1), install MCR's, SE-254e cams, SE high performance bearings, and a TTS Master Tune with 2 Dyno Sessions(befor and after break in)!!!......I see a kit in the SE Cat. that has all of these parts and more, SE push rods, high lift springs, SE 259e cams instead of the 254e's and a clutch spring. The kit also comes with the Super tuner instead of the TTS. I would only be a couple hundred moe for the kit. I have also noticed peope talking about adding the SE compensator and the Timken bearing Sleeve and bearing.........Is this all nesessary or should I just stick with what I've got on order now?????.........and thoughts or advice would be greatly appreciated!!!!!!!!................Thanks and keep the rubber side down!!!!!!!!

I've got the SE kit you're talking about and I really Like it. The one thing I will say is the 259 cams come on later(about 2500-3000 rpms) than a lot of people like. I plan on having my heads redone in the future tho so that will really bring on the low end and give me the full potential of the mods. I liked the price if the kit because it included the tuner. You should be able to order it from surdyke at a nice discount too. You might want to consider the fuel moto 107" kit as well. I know lots of people really like the value of it. There are so many different options it's hard to decide. I don't know about the other stuff but I'd like to hear those answers myself. I'd also like to see what the consensus is on the MCR heads vs having stock heads reworked by someone like Hillside.

I luvin my set up as per my sig. I just went with the flat tops, where the next step up for pistons would of costed a $hitload more. Mechanic said unless you stacking TQ/HP for stage 4...I wouldn't notice the dif.
I would get another doc's opinion on it bud.

Thanks for the input guys. I'm def. gonna go with the 103" and flat top pistons at 10.5:1 comp. Think im gonna stay with the 254e cams because I like the smooth tourque and HP curve i've seen on some of the dyno graphs. With the higher compression I just don't know if I would be tapping the motors full potential!!!!! Hope it's the right call. Does anyone know if the SE compensator or the Timkin bearing sleeve would be good to have in a build like this? Also my Tech swears by the TTS Master Tune and says he has a lot of sucsess with it. He says it's a much better tuner than the SERT!!!!????.......Any Thoughts??????

Just for the heck of it check the dyno sheets on the woods TW777 cams, available on the fuelmoto site, they also have other setups with dyno sheets.. TTS is good but also look into something with autotune shch as PCV or Thundermax.

I would think with the 254e cams you leave a lot on the table. The 257e's with some headwork would give you the low end you want and all the way thru to the redline. Thats with SE stuff, go to woods and then you could do a little better. The TTS is a good tuner but if just a little better if any than the SE tuner. The thing you need to look at is the guy tunning it comfortable with the tuner you have? I would get what the tuner wants to use you will get a better tune with it. Most times it's not the tuner that works better than another but the guy who knows how to use it matters more

cams are hard to pick, and are very personal, but I went with a HD kit and am very happy. Good power and very drivable, but if I had to do it again I would do the 107" from fuel moto. I put the kit in to stay a step ahead of the rest, and now everyone that buys a new bike gets it for free... lol, go figure...

Btw how much would a throttle body add? I think I was asked that option...but I had to put a spend cap before I went really stupid at the moment of ordering....I could be with a 120 kit now and living in the dog house
And how hard is it to add after the kit has been done?

Your probably gonna need a better starter later, and even though they say you dont, I'd look into compression relief, manual or auto.I have a 103" IN MY 09 sg, right after needed a starter clutch, then a starter, then the the starter destroyed the splines on the clutch basket. My 2012 Blackline 103" came with ACR, go figure.
I have an HD pro tuner in my SG, but honestly, I like the Cobra Pro I put in my Blackline better. No single map, but constantly tunes in real time to any speed, altitude, etc.
