I'm having a problem on my HP2 when I get on the throttle at about the half way point.
Primarily in the first three gears when I crank the throttle open, the engine starts to cut out and in and out and in with a cacophony of back fire's and pop's through the tail pipe. The bike starts to buck like a wild horse until you back off the throttle. In the upper gears it happens as well but at that speed I don't really care to experience the control issues associated with it.
Prior to this, I rode the bike about 300 miles with no problems and after sitting for a week, this problem appeared on the first ride.
I've also noticed that sometimes when the key is turned on, the computer does not go through engine, ews and lamp checks. When it does go through the check, I get no errors.
Does this sound like a computer problem?
Anyone else have a similar issue?

. Very sorry tale indeed. Was heading North to the Taranaki region for a bit of an adventure with a few mates, it was disgustingly wet and miserable but always keen I suppose. I made it 16kms out of Wellington at which time I went from about 90kph to 90 degrees to the centre line in the space of a heartbeat, the engine just quite and everything locked up 
. Fortunately very little opposing traffic, so no distractions while regaining some sort of order. I think Kerry, the guy riding behind me, thought I was showing off. At least he stopped to see that all was okay. He did say from where he was sitting it all looked rather dramatic 
I was too busy working on the self preservation thing to be too worried at the time. Looking back on it, she could have turned out really bad, especially if I'd actually ditched it. Sadly, was not able to get the bike going again, so sat out an hour or two waiting for Dealer transport on the porch at some car haulage place. At least I had shelter (and my thermos of soup ) so was pretty fine about the whole thing. As it happens Kerry ended up about two kms up the road in a gravel layby, something also stuffed on his GS (turn out the fuel pump sender unit fried itself). So we had a good chat on the way back into town in the Transit and decided we just weren't meant to go on this trip. Popped in to talk with my "service technician" (what happened to good old "mechanic") last week and the diagnosis on mine is very sad. Seems that Herman forgot one or two of the cable ties on the day he was putting the HP together, consequently the wiring loom chaffed through on the frame where the tank is mounted (right hand side), arced 5 or 6 wires and fried the main processor. Loads of faults being returned and unable to clear. Must say it's the first time in 20 odd years of owing BMWs that I've encountered such a major problem. Previous bikes have all gone through many miles, mostly torturous adventure rides, without any problems - so I'm just putting this down to a bit of rotten luck. Ah well, warranties are handy I suppose, BMW are freighting out all the necessary bits (including a whole new loom) and will all be back up and running for the next ride we have planned over the mighty Motu Road up in the Bay of Plenty middle of August.
