Liken it to Dell Ortos with accellerator pumps -
you snap open the throttle = big dollops of fuel get squirted in instantly = instant takeoff.
GS fuel pressure regulator = 3 bar
K1200 pressure regulator = 3.5 bar
I can see where the additinal line pressure would get more fuel injected for the same 'open' time for the injector, but wouldnt this increase fueling throughout the range ? thats not to say thats a bad thing.
Has anyone done this and had there bike dyno'd , that would be interesting

Just like RickG, I was confused as well... and if RickG is correct, then
why not fit an R1200GS pressure regulator, rather than a K1200RS regulator to an 1150 or 1100 then
Just think what sort of diplomatic incident that would cause

Sounds interesting, any more info on such a thing?

Whats confusing ?? just fit the higher pressure regulator. Does it matter what model it's from
I can confirm the the HP2 is 3.5 - just checked

Is fitting a K1200RS fuel pressure regulator to your GS simple?
edit: ... just seen this... do you really have to remove the ABS unit??

Was there ever a response to this? Do you have to remove the ABS unit?
***Warning, 8 year old thread resurrection*****....
No.
The pressure regulator can be removed with it in situ, and the subframe in place. But only from the R/H side of the bike.
Its a tricky job though
I seem to remember having to be quite 'persuasive' a couple of times. I'm also not sure it's not at the root of my (self inflicted) setup woes either.

Will it work on an XT660z?

Just done it on mine. Plugs a nice colour now. Runs well. Strong top end.

This is an 8 year old thread and was the prevailing wisdom at the time.
I run 3.7 bar on my r1150. But if you don't change the stock O2 sensor, the Motronic "adapts" to the higher pressure and negates it.

Do you mean to replace it with the K1200RS O2 sensor as well as the regulator?

In my case, rather than pull out the old regulator, I added the aeromotive in the return line. So the fuel flow from the tank to the stock 3 bar regulator. Then from there, through the aeromotive back to the tank.
That way I also could vary the pressure and get 3.7 rather than 3.5. This created a total fuel flow boost of 10%. I wanted 4% more fuel flow to compensate for running gasoline with 10% ethanol, and 6% more fuel for a much better running engine.
I then locked the 10% boost in by replacing my stock O2 sensor with an innovate Motorsports LC-1 set to 13.8:1.
I didn't know it at the time but the Motronic has Mixture Adaptation capability which means all I really need is the LC-1. The Motronic calculates long term trims which then, after several tanks of fuel, adds fuel everywhere.

I have a Remus decat and open can. Rt tubes. K&n and I've fitted a 3.5 bar pressure reg. what's the best next step for improved long term engine performance. Cheers
