I have one of those early STs, an 07, and it had a fuel pump trouble. When it was hot and the fuel level was low, it would stall. If you filled the tank, the trouble cleared. The consensus is that at low fuel levels, the pump would overheat. I was able to capture a live data log file of the failure with a GS911 and you could see the fuel pressure dropping off. I'm not so sure about the guy's statement that it tripped the CANbus, because there was no indication of that. I know several people who had the trouble, all cleared by replacing the pump. I thought that around the time mine was replaced last year they started using a new pump. So it's kind of disconcerting to hear that the problem still exists.

As an aside, related to your GS cam chain trouble, when my startup rattle began to get my attention, I cleaned the damper and replaced the tensioner spring and discovered that the original spring had been superceded by a new one that is a fair bit stiffer. The new spring significantly reduced the startup rattle.

These engines seem to normally be pretty noisy. When you hear something new, it's time to investigate.

They sure are sweet bikes to ride, though. Mine's been to the 49 states you can reach without Jesus tires.

Yep, that sounds about right.
I also believe it's disconcerting to hear that this has been a well known problem for some time, though somewhat in the past, and therefore something that should have been corrected, suppliers changed or whatever.
Equally perplexing is the absence of replacement fuel pumps in the United States, seeing as how it's the same fuel pump as your ST, a well established bike.

Like I said, due to great timing for a something like this to happen, it's no big deal to Nancy, and I expect we wont have this problem recur in the future.
Now, if more new 8R owner start checking in with the same issue, we'll have us a real deal BMW conspiracy on our hands!

In the mean time we'll have a blast riding this awesome bike.

Your insightful comments about the GS cam chain I'm sure would be appreciated in the Gspot forum, as it's a hot topic right now for GS owners who are racking up the miles.

F800R ready for a 16 hour trip from Stavanger to Trondheim, Norway
This was in august 2009, 8 hours of rain during the ride.
The bike preformed beautifully.

Awesome!
any other pics?


Welcome to ADVrider, nice first post... we like photos!




Tomorrow I'll be installing Ohlins' BM 909 shock and fork springs in the 8R, install photos and DIY to follow.
Well, honestly I'll be helping/supervising since I'm one handed with a hurt wrist from a bad crash in Death Valley a few days ago.

This afternoon took a hopeful new F800R owner to the BMW shop. They had one with ABS/computer/heated grips. Friend is about 6'1" so he's opting for the lower peg option. Sounds great. Feels good. Has the looks/style he's after. Maintenance is minimal in terms of scheduled service.

And speaking of front fenders the ones on the non GS F8s are very flexible. There's no support on the back half. The original Fenda Extenda for those bikes was about 6 inches long, but the fender was too flexible to support it, so they quit selling that version and came out with one about 3 inches long, which is about useless. The sardine can is very vulnerable and should be protected with an undercowl or something.

Joe, I was shocked to see that video. Best wishes with your wrist and the bike.

OK, plenty of opinions about how the bike looks around....
but what really matters to me is how a bike rides.

Here's a quick edit video I threw together of me having a great time throwing this excellent bike around in the Malibu canyons.
Shot with a Drift HD 170 Stealth camera, Manfrotto Magic Arm mount, edited on a Mac.

Cool video. Gorgeous roads. Love the bike's appearance, but had no idea they sounded so flatulent...like a tractor really.

You have to just get past the sound(s) of the engine and ride it. I thought mine had serious issues from the clatter when I first got it and was not in love with wiht the flatulent (good description) sound of the engine - but now I embrace it and enjoy the ride,
