If you were going to pump your motor up what is the most HP you build it to, with the fuel that we have these day or the stuff that's coming down the road?
This is for every day use

[Supershooter]

There are a few things we need to be mindful of when we start talking about building motors and making power.
1. There's more than one way to skin a cat... there are thousands of ways to assemble parts and pieces to make HP and TQ
2. When we look to increase HP the pars that we use can only take so much stress before they break; therefore if your looking for an everyday rider maybe extreme HP and TQ aren't the correct choices.
3. What type of riding are you looking to do? Are you cruising the interstate, racing your buddies on the street, or just running country roads with your BSR.
Sometimes changing drive sprockets and belts can give us more low end responce than changing cams or increasing displacement, or increasing compression.
There are lots of people on this forum that have done just as many different configurations to make their bikes perform the way they want.
Good Luck,

Supershooter is right on the money.

I live at 6300 feet.  As you go up in elevation, the lighter that air, and the result is that your compression ratio drops.  If you build a motor at this elevation at high compression and stil use pump gas, you will have higher compression ratio at sea level, and pump gas will likely result in pinging.  So, when I built my motor, I built it with 10.1-1 compression at sea level, which resulted in ~9.3-1 compression ratio at home.  End result is, I can use 85-87 octane at home, and use 91 octane at sea level and the bike runs great-no pinging.  I also chose the right cam to put my powerband sweet spot where I ride 80% of the time, based on bike/rider weight, solo 100% of the time.

My biggest point here is, compression ratio means a lot when building a motor, AND you have to take into account how its ridden, as well as where.  Just as Supershooter states, there are many, many variables to get there.

To chase HP and TQ numbers is nearly meaningless.  You should build the motor based on how it will be used and where you need the powerband, based on how its ridden and where.  The HP and TQ numbers will fall out based on the proper build, and are what they are. 

BTW, my end result the bike acclerates up steep grades almost better than on the flats.  Hard to believe, but its screams when it gets to the hills here in the Rockies.

Thanks for the input, i have spoke with differant builders and none of them came back with your comments, they make scents
I will ask more question

If you do have any ideas I will be looking forward for any input.  I ride two up, and pull a Aspen classic Tent Trailer, trailer loaded about 700lbs, When we went across state scales we come in around 2200LBS loaded down.   
Trying to travel the great USA one mile at a time.

Not sure if i need to do anything, we did 4000 miles on this last trip went through MT,ID,WY,Or,Wa.
When we travel I run with three other couples, I'm the one that brings up the back of the pack.  We try to travel back roads. Take the long way.
When we come up on slow traffic, more then three cars, or a couple of Semi's you need some extra HP to stay with the pack.
Not sure how many times half the of the pack got by slow cars, and then had to stop and wait down the road, and then have to go around the slow travels again

I'd recommend spending some time looking at changing your drive sprocket and belt. The are some posts in the forum about using a 30T and a shorter belt, they seem to get their power to the ground more effectively than the rest of us. They do run more rpm's but if your not pounding 1000's of interstate miles I'd look in that direction. Steve at FullSac can also be a good resource for changing drives and increasing HP and TQ.

A Baker 7 Speed might work well in this case ?

Like Supershooter said, I am running a 30 tooth primary sproket and one tooth shorter belt. I have the Fullsac X-pipe and 2" cores with steves tuner. I can tell you this, my bagger rips 09 serg. You won't have any trouble passing trucks fully loaded. and the bike will still bury the speedo.
