2003 sv1000n cheaper superbike motor build

The man with the know about this stuff was schmidt314 , but he hasn't been around here for a few months now......

Started to reply yesterday...but thought about this for a while. The statement about building an SV 1000 Superbike motor that was followed by not having unlimited money supply has a flaw. They tend to cancel each other out!
Not telling you not to try. My history, even here, shows I now have LESS money because of some of the stuff I have tried!
Be realistic. There never was a "Superbike" SV 1000 engine. Even Schmidt314 would likely agree with that, and he has built what are likely some of the best SV 1000 engines that could be built. They CAN be more fun and rewarding than building the more common inline 4 engines.
From my experience the wall that gets hit against most often when modifying these or other engines, or doing engine swaps is the Engine Control systems. From bumps on the rotor, to injector setup, to coil issues, to cam position sensors, to computer issues. Hard to make all these work like they should. If you are going to make the kind of power adding the 1050 cylinders and other parts mentioned.....probably going to need aftermarket connecting rods. Meaning a full tear down and balancing of parts. Not sure if the 1050 cylinders fit without opening the case bore. That too would mean taking engine apart to be done properly. Not sure how much the TL cams add in power? I know the TL turns more rpm in OEM form, indicating the cams had more duration and probably lift. But.....SV cams work with the factory ECU. That in itself eliminates a LOT of potential problems. You could always add TL or SV aftermarket cams later.
The only advice I would give is to stick with SV cams, at least to get the project up and running. Money being the most important reason, followed by technical issues of going to TL parts.

now all I can nowhere near what I can afford , but this is what Chat GPT told me I needed to get it up to around what I wanted in horsepower range

Well, you have somewhere over 120 hp if I recall correctly. So 130 is likely possible without going deep into the engine. Maybe closer to 135-140? Don't know, but some here will know that. There are some dyno sheets posted here somewhere too.
Almost without exception, those "high" horsepower engines become not happy as street bikes. An SV 1000 CAN be one of the best sport touring bikes you could own. But it is NOT going to outrun modern liter bikes you meet on the street. They can be modified too, and they start a lot higher HP than you are.
In anything but a drag race, engine power won't be as helpful as a great suspension and braking. Get on the Tail of the Dragon and tell me you need 150 hp to be fast.....while you are being passed by bikes half your displacement! GSXR forks are a start. Might even recommend an aftermarket rear shock that is setup for your bike. Even the stock GSXR forks might be helped with aftermarket parts. Do those two things, which is a lot less money than engine work, and then master that setup before taking the engine clear apart for another 20-30 hp......

On the other hand, I LOVE to see projects. As long as they get completed! So maybe some here will chime in on what they done to get power from their SV 1000.
