Default Are these good numbers? Dyno stats

Tried to upload the dyno sheet on my Iron but I couldn't file was too large since it is in PDF format. But here it goes...

Final Tune
Max Torque=77.59
Max Power=95.35
2010 1200CC XL883
SEAC STAGE 1
Vance and Hines 2 into 1 Competition Series black exhaust
Woods Camshaft W8S
CHD HEADWORK MRW
SUPERTUNER in DAKOTA DIGITAL BOX
INDUCTION MODULE CLEANED UP TO 42MM

Contacted a few vendors to see whats the next step needed to get this bike to where it puts a smile on my face... Not that it does a bad job at it but it could be made better...

So for all you Tech Gurus, performance DIY, etc... What would you do next? Take it to a 1250? do additonal headwork, pistons, change out the cams, etc?

I would like the Torque numbers to increase for sure..

Take it to the dragstrip and see what it does in the quarter is the next step. A machine can only tell you so much what "power" your bike has. And dont go to one of them online HP to weight calculators that tell you what your quarter ET will be. They are way off.

A better AC/breather like suggested in your performance intake thread will take you over 100HP. After that you are are in the realm of diminishing returns. Time to start working on the suspension so that you can do more than go fast in a straight line.

There are FREE on-line converters that will do it for you, Like Here
It's best to then put the jpg images on something like Photobucket and just past the "IMG" links in your post.

Have another go at loading your dyno chart. A picture paints a thousand words! The shape of the torque curve is everything, as that is what makes your bike move and gives it usable performance. Numbers mean little.

As an example with one set of pipes my Glide gave 102HP/103TQ. Changing pipes I got 101HP/107TQ. What those numbers do not show is the 15% extra torque I now get in the low/mid rev range. My bike is way more rideable and just plain nicer to ride now.

great job on your engine. dyno sheet looks pretty good. If you want more power you are going to have to have all parts working as one. I wouldnt throw just cams or just a 1250 kit with it if you want to have a decent power gain. If you just throw a few things at it, i dont think youll get what you are looking for.

A hammer 1250 with their 600 cams and 1200 or xb heads with crush or sledge porting will make some serious power with a goo exhaust.

your sheet looks pretty good to me. tq curve has a nice curve to it.

here is a dyno sheet from my hammer motor with the parts mentioned above.

Hey Madnss- are you carbed? I noticed how rich you're running between 4k & 5K. Is that on purpose? Educate me, I'm curious. btw, I'd like that kind of power...but a little apprehensive of what I'd do with it too.

Carbed. It looks worse than it is. That's a wide open pull....all main jet. I'm assuming it's pipe/cam reversion.
