I would wait and go pick the bike up before doing anything more. Take it out for a ride and see if you enjoy what you have today. Chasing dyno numbers is just that......... chasing numbers. These guys are talking more compression to get better numbers and that brings along harder starting in warm to hot riding conditions, better fuel requirements and on and on. Just being run on a different dyno may yield better results. Take a look at what range you ride the bike in not what a dyno sheet says first. Then compare only that area of the dyno sheet. I see way to many guys get wrapped up chasing numbers these days who will never even use the extra 5 HP as it's in an RPM range that you do not use. Remember that Torque is what gets a load moving and an engine with better Torque in the RPM range you ride in is going to feel and perform the best, unless of coarse you plan on drag racing your bike.

   Amen   Steve,
Not many listen to reality and logic.

Scott,

What do you think my problem is? I know dynos are a fickle but I was comparing this to a friends bike with less compression and a milder cam. I put a 50mm Screaming eagle TB that I don't think he put on. Do you think it could be all in the exhaust? I have Bub 7 slip ons with the stock header pipes. What 2-2 pipe have you seen the best sucess with?

I will probably ride it this way for a bit and see how it runs before switching to a new exhaust system. I like the looks of the Rinehart crossbacks, how do they perform?

What do the heads flow?? Intake/exhaust?
That 50 is probably pinching things, as we are using 55mm HPI's on our 98" Hi-Output set-ups now.
What is the ccp?
We see that D&D pipes work very well, as does 2/1 Supertrapps.

I would not speculate about the heads even if I had flow sheets, just me I guess.
I have made 1.14+ hp and tq / cu.in. on these motors consistently even with heads that flowed 15cfm less then the stock CVO head, and with a flat as a pancake torque curve. Just creates a slippery slope to specualte on the heads.

Its depending on how much the tuner did, was it a "full  tune,"   or just a "fluff" tune 

[Zinister]

The mech put a tapered 2-2 cycleshack exhaust and it showed 222 Hp and 126 Tq. Guess that means the Bub7 slip ons are my problem. The Cycle shack was a 2 in. stepped header set.


Anyone have suggestions on what 2-2 exhaust to get. I would like to perform at least as well as the Cycleshacks.

i use the Bassani Pro Streets on my 09 Springer.

Doc,

I agree with you if you don't add pistons but, I was expecting at least 120/120.

I don't like the looks of the 2-1 exhaust. Knowing that what is the best performing 2-2 exhaust. I have been told not Big Radius. Damn more money!!!

I have the Drag Specialties Staggered Duals (made by V&H) with the "quiet baffles" (not that quiet) for added back pressure.  The look like dual pipes but have and X in the middle that you can't see.  Searched around on the net and got them for $375 two years ago.  Can't remember where.  Run great and sound awesome with the baffles.  THe X runs smoother than the big radius I ad on my Night Train and way better flow than the stock exhaust.

What ci?
What cams?
What altitude?
What humidty?

Lots of variables.

Similar work on mine less high compression pistons resulted 104HP 105TQ at 6200ft

222hp WOOOOOHOOOOO

[Zinister]

Lol, 122 HP doesn't sound as good but......

[Zinister]

DesertHog, did you look at the previous posts as all but the Elevation has been given.....640 ft above sea level. I don't have the dyno graph as I'm traveling for work but will post it when I get back.

What size injectors are you using with the 50mm TB?

The TTS gives you a calculator and I believe you'll need 5.3's to break the 120 HP mark.

[RayG]

Are Bub 7 slip on's very close to the RHTD set up?

Thanks
