Those numbers are almost exactly the same as mine. Put a fork in me, I'm done too. Nice improvement over stock.

I am in the process of acquiring the pieces to go big bore on my '04 FLTRI. I got a set of S/E big bore jugs on the way. I have a friend in town who is a machinist and does work on HD cylinder heads. His head work includes porting, shaving, bigger valves (I'm assuming either 1.9 or 2.0 intake and 1.6 exhaust,) new guides, heavy duty springs and compression releases...all for around $750 on my castings. He said these heads work well with flat top pistons. I am currently running 26G cams and have a Stage 1 breather, SERT and V&H True Duals. I have read a lot about Big Boyz Heads. Here's the thing. I want good torque numbers. I'm not as concerned about HP, but if I go with Big Boys heads and decide later to go up a size on cams (probably not bigger than a .510 lift,) would the Big Boyz heads work with something bigger than 26Gs? Will the heads my friend wants to build be too much for the 26Gs? I don't want to spend a small fortune trying to find the right combo. Any advice will be appreciate.

wtf i just had a dyno today and my numbers are not to impressive but the bike has so much power i like it. Some said earlier the the sae is more accurate then the std. This is my build 103 big bore screamin eagle heads,se forged pistons, se 259 e cams, adjustables,mcr,stage one a/c, se super tuner,battistini/ness head pipes, with thunder header slip ons. Hp=91.10 tq=101.70. Is something wrong is it my true duals do i need a 2 into 1. The tuner said a 2 into 1 will give me 8 t0 10 horse power more as well as raising the torque numbers. Doeas this sae or std really effect the readings off the dyno. Iam confused please explain. Do i need to take it back or what. Thanks in advance.

I'm at 85.21hp & 101.27tq and all I have is SE Air Cleaner, SE 211 Cams, Same Head Pipe with Rineheart slipons and PC-V with custom map.
Talk to Kevin at Mitchell's Modesto H-D or RC Cycles in Hayward to get another 2cents worth.
The main thing is that you are happy with the way it rides,as long as your not trying to build a dyno queen, if that's the case then get a 502 boss hoss put a blower on it and run nitro through it

Looking at the dyno sheet I'm wondering if they just dumped a canned map in, did a dyno run and called it a "dyno tune". Seems like a decent tuner should have been able to tune out that big dip between 2500 -3500 rpm. Those HP/TQ numbers seem awfully humble. With that said, I defer to the experts for their opinion on this....
