http://www.nastybikes.com/cylinders.htm - $1,000

I am really wanting this.. I'm guessing numbers of +150HP & +150lbs•ft.. 1475cc

It's relatively inexpensive compared to a 88ci for $1,200

Can y'all give some advice?

You might as well go to 190 incher..as you wont be able to dial in either or on the Buell fuel injection.. Now CArb is a different story..

What do you mean I won't be able to dial it in? The 90ci will need larger injectors..

I'd like to see a pic of the cases bored out first, cost may go up as you start buying cases until it comes out right.
Seriously though, there is so little meat between the cyls. with the stock bore I can't imagine what's left when you take out enough for 3.875 in pistons (is 4.010 the cutout in the case?).

there is plenty of meat left in the cases after the cases have been Case Bored for the larger cylinders 90" is not a problem , but You can add minimum of $275 to the 90" piston cylinder kit right of the bat for boring the cases plus shipping ? and You better have a lot of trust in the machinist with a 4 axis cnc machine , Hammer Performance ? Do You know if Your heads can flow enough air to justify that size bore ? Is the stock throttle body able to be bored big enough to handle the air flow needed ? Yes You can build a BadAss engine but it is gona take more then slapping on some big bore Kit !

All of the above...What will you use for a Computer to control all this??? IF ya think the stock ecm/race ecm will handle this Sell your XB and get a New Buell 1190 or whatever you will never dial in a 90 incher sorry buddy
This has been talked about for Years and years...

You would be lucky to see 130hp and ~110ft-lbs and even then, there is no way you would ever see those numbers if you think that a $200 difference makes it "inexpensive". You will have to spend $5000+ in parts to build the motor with everything else it needs to reach its full potential.

Griffmeister concerns are partially correct. If you case bore the cases for the 90" barrels and plan to run anywhere near 120hp then You need to NOT USE ALLOY CYLINDERS ! the alloy cylinders will not be ridged enough to provide the support to the cases , You need to step up to some good steel lined cast finned barrels , not aluminum or other alloy that is plated bore. But D_adams has got ya hooked up :-) EBR 1190 SX

Most places, including NRHS where I work, charge around $275 for case boring, not including disassembly or new bearings, as you definitely want to change the bearings while you have the cases apart, and they run another $200 or so I believe (I could be wrong on that price). As thin as the sleeves are on a 3.875" bore you do not want aluminum or iron lined aluminum cylinders. If you want iron lined aluminum, go with the 3.813" bore 88" kit, which also has the added benefit that it doesn't have as much of the piston skirt cut for clearance on the inside edges of the pistons, so an 88" kit will generally last much longer mileage wise than a 90". On DDFI you will definitely need larger injectors and good tuning software to utilize the extra inches, but you will more than likely want headwork to make more power, as the heads will really limit the power output in stock form. If you're doing a 90" kit to lower cruising rpms to 2600 or so, then you are wasting effort because these motors do not oil themselves well enough for those lower RPMs and the cranks are balanced for higher RPMs as well. 3000-4000 is really the sweet spot and most reliable as well.

Oh and as mentioned above, the heads are really the limiting factor in power, not the cubic inches, though the CI do help a little bit, and get the power much sooner. To get 150 RWHP you are really barking up the wrong tree nd fighting the wrong battle. A turbo will get you there a lot faster and more reliably, though you'll end replacing the same parts either way, just with different spectrums.

This project sounds like a rabbit hole I've run down more times than I care to admit.
IMO the Buell engine is already 10lbs of stuff in an 8lb container; there aint much "RELIABLE" hp left in that container.

My advice, want more hp?
Get a different bike...

Personally, I think that's good advice.

I agree. Its a cool thought to have a high horsepower buell but I just don't see the reliability being there. I personally would just do exhaust, air filter, maybe intake mod, and ecm program.
