Question about Suzuki Motorcycles
I have a Suzuki GSXR 1100. Bike always starts and runs. Some times it runs awesome, other times it runs poorly, as if its running out of fuel (but its not, because i bypassed the fuel filter) I'll Shut it down, and restart it and maybe it will run great again? Some times it will and some times it won't. Its unpredictable. I've taken apart the carberator to clean it, looks good put it back together and same thing.

Go to toro.com then click customer care, then click manuals and parts. Type in model no. and download the owners manual. This should get you the spark and flywheel gap. Probably still something in the carb. Some orifices are very hard to find and to clean but they must be clean. Also check for dirt dopper nest in the muffler.

Yes you may need a carb kit. It is not good practice to by-pass the fuel filter. The orifice in the jet is very small.
But anyways, There Could still be a blockage inside the carb, a small leak at the manifold, or the jet is worn out.
Let me know how it goes.

The first thought that comes to mind is a high pressure oil leak. The
injectors have a snap ring on top that sometimes becomes detached and
it will create these symptoms.
When you depress the brake it sends a signal to the PCM (Powertrain Control Module) and the PCM increases the idle because it predicts you are about to shift into gear. If the truck has a high pressure leak inside the engine it will have a hard time building pressure initially and once the oil warms and thins out the High Pressure Oil Pump cannot hold the pressure and the oil leaks faster because it is thinner.
You may have a leak around the pump area which is under the turbo also. The IPR which is the regulator that controls the oil pressure may also be bad. It is directly under the turbo as well. The IPR is located under the turbo on the High Pressure Oil Pump cover. You stated the seals were leaking on the IPR itself? If the orings are damaged or if the screen in the end of it is collapsed or even punched through with a small hole it will need replaced. Screen damage is usually a sign of debris entering it from either dirt from a previous repair or something is coming apart inside.
Make certain you have clean oil and fuel filters. Yor may want to check fuel pressure as well. It should be somewhere around 55psi on acceleration.
Additionally, I suggest check for voltage at the connector on the fuel pump. The pump is mounted in the filter housing on the frame and the connector is at the front of it. The pink and black wire should have 12 volts with the key on for about 30 seconds. If the pump has voltage but is not running, then your pump has failed. If there is no voltage then check fuse 2.40 in the central junction box. This is the fuse that feeds the inertia switch through the fuel pump relay. I have included a fuse box layout and a wiring diagram (click over images for zoom)...
Additionally, will need to scanned the PCM to know if some fault code is stored there.
Keep us updated.
