    This is from another forum but for me really nails the future of GS/GSA bikes in the BMW line..and for me to it is sad.

    In Motorcycle News, UK weekly bike newspaper, they announced that BMW will be fitting a detune HP2 Sport engine DOHC engine to the GS. Only minor cosmetic tweaks.

    But 22 bhp power boost.

    They may drop the R1200S and HP2 Megamoto which was limited run. However, a lower spec Megamoto may be moved into mass production.

    So DOHC...revving to 8750rpm rather than current GS peak at 7k. Should be fun.


    First my '07 GSA has about 100 hp and honestly 122 hp is way over kill on my bike since I ride it 90% off road..spinning to 8750 rpm rather than keeping the power and torque down lower is also not what I would want in an off road bike..as a gentleman on another forum commented that BMW is shifting the design of the GS series to pavement touring...this would verify that.

    My question: Is the HP2 the bike which BMW required periodic major engine rebuilding?

    Can't remember which bike it was that does require it..

    Well, I had 6 good years on my 06GS before the fuel pump controller went. The bike had all the symptoms of a dead coil - engine cutting out under load accompanied by a distinct sputtering sound. As soon as I let up on the throttle, the engine settled and sputtering gone. Only under load.

    I replaced both secondary coils ... nadda.

    I finally rode it to a dealer where they scratched their head and kept my bike for over a month, letting the bike travel through the hands of several mechanics trying to figure out the problem. They then handed me an $800 bill to diagnose and replace a $148 part- the fuel pump electronic. It took that many hours to determine what I see now as a common problem??

    Remove the side panel, lift the fuel pump cap, and simply replace the electronic. I'm not happy.:becca

    My original one worked great,but it was replaced under the recall by my dealer. The improver one failed 2 years 6 mo. later as enough water leaked by a pinched o ring to corrode the plug to the fuel pump. Not much rain around here last few years or it may have failed sooner. Told it was out of warranty.

    Real smart to put this thing in a spot that fills with water!!
