Prior to my last mod, all the work that I did I tried to be conscious of mapping. I tried to do what I could with minimal impact on the fueling system.

With this, you need to decide if you are going to spend the money and time to generate a new map or have someone to it for you.

Here is one of my mods. I had Axtel Sales perform this work and I assembled.

11.2:1 domed pistons.

Yeah i have 10hrs of dyno time factored in also is it still a 1200 or a 1250?
Are you happy with it?

Its still a 1203 plus 0.010.

I like it, the bike pulls strong thru the rpms. I still would like more power!!

I also removed rotational mass from the crank. This allow's the motor to spool quicker. This was done in two ways: first by replacing the OEM parts in the primary with CNC'd Aluminum parts and secondly I CNC'd 12oz. off of the stator rotor.

Increased throttle response.

This store has the primary/clutch parts.

I'm sure these guys could help out.

Check out the 1474cc kit.

The bike is quicker and pulls hard. The motor feels stronger than a 1203.

Cubic inch has been the surest ways to get big numbers in the past, today?

There is a bolt-on turbo kit coming out this year for our XB Buells. You might want to research this as a possibility.

Brian Olson is the guy you would want to contact.

He has told me that they are working on one and should be done soon.

Yeah i also looked into the actually aerocharger it self and it seems like a good turbo to build a kit from on a buell. It has no oil lines as it is self oiling can be mounted anyway i belive has really fast spooling Would not be hard to build a kit my self from..

Same here...I would have to remove mat'l from the top of my piston were as you can run the stock.

If I was to have a do-over, I would seriously consider this as the mod of choice and I may still do it.

It should go well with my new throttle body set up!!

I also called the company making the kits he told me between 6-8 weeks till finshed he said it is a complet kit intercooled also will come with tuning softwear priced around 5300. Said it should make around 125hp at the wheel. He said they are just waiting on hot weather basiclly to finish testing.
I am really interested in it

how are they fueling this? I work at Harley Davidson, and I work next to a tech and what he does all day is attempt to find a way to fuel a big bore kit or a turbo setup.

To our knowledge it is not possible for our injectors to produce too much more fuel. We both have similar bikes, 05 xb12's with race kits, we are both very nearly at the limits of our injectors capabilities. I've read of turbodoc drilling out his injectors, but how? They are angled...

If anyone has any ideas other than VRod injectors please please PM me, I have been researching this for quite some time now and I'm about to just plain give up on a 120+hp semi reliable xb.
