BMW R1200R R1150R/T F800 K1200R R1100R/T R1250R RnineT Message Board

I'm just wondering how many folks with DOHC engines experience this? I have a 2011 R1200R. My main riding bro has a 2012 R1200RT and we both experience this a couple times a week. It usually occurs within 20 miles of start up. Not necessarily the first run of the day either. It can happen any time when on an all day ride. It always occurs when adding rpm for a take off and usually makes a very loud clack/knock and dies. Restart is fine and it runs fine after that. Neither of us has had it happen more than once in a day. BMW says there is no issue and they have never heard of this (Their standard corporate rhetoric of course!)

I've got an '11 model year and have not had any issue.

'12 model here and never a stall. The noise you describe makes me wonder if your fuel is high enough octane. The only time I ever came close to a stall was in a similar situation to the one you describe but I had filled up with mid grade (89 octane with ethanol) rather than my normal 91 or 92 octane without ethanol. I blipped the throttle after only having ridden a couple hundred yards and heard a couple knocks and the bike almost stalled. It hasn't happened since and never when I fill up with the good stuff.

Maybe try a different station. If you have ethanol in your gas, you can go to pure-gas.org to find a station near you that sells the good stuff. They also have a smart phone app you can use that gives you directions to the nearest ethanol-free gas when you are out on the road. I've used it successfully to find the nearest good gas while out and about. It's worth a try.

Stalling hapend to me few times,that vas my mistake with clutching at take off.One plate dry clutch is a different(not as much forgiving as a multiple plate oil clutch).

This has occasionally happened to me with every big single and twin I have ever owned, more often after a cold start; feels like a leaned-out cylinder firing before TDC at very low rpm. Occasionally I have even fallen over! I agree with Steve H that it is simply my mistake, when I get lazy and don't match the clutch to the throttle to the rpm just right. But maybe a "booster plug" might help?

I have booster plug installed on my bike few months ago.Yes Exprof,it helps somewath.Then I went back in to "old fashioned"thinking:richer fuel to air mixture definitly washing off oil from cylinder walls=more wear.Disconnected booster plug,reconnected to original temp.sensor and driving it as it is.As miles accumulating,geting more used to bike,it is not stalling animore.My personal message is:the factory did the best in every aspects.So guys,it is up to you if want some changes on your bike.I like to see durability,longevity on my bike.Am I gating old???Well it is happening.

I have a 2008. I have not had any problems with stalling.

I agree with you completely. I am too getting older (aren't we all?) But long ago I gave up on thinking I needed better performance. My R is older than most of those on this particular forum, an '04 with about 43K on the clock. It has more than enough performance for me. At this point in my life (I'm 58) I want my R to last me a very long time. BMW knows their stuff. I don't know anything. My best bet is to enjoy my bike like it is and I do!

All the booster plug does is raise the AF ratio to a reasonable level, within the parameters set by BMW. It is not a performance upgrade as much as a driveability upgrade. It doesn't wash oil off the cylinders or every motor with an optimal A/F mixture would be toast. The bike runs cooler and is less likely to pre-detonate with the booster plug which equals longevity. EPA mandates lean to "save the environment" not increase the longevity of your motor. Lean = hot = premature wear.

According to the map I'm in a dead zone. The nearest pure gas places are a 100 mi away in any direction. ( N schenectady NY, E worchester Mass, S Bethlehem PA, W Binghampton NY. I'm located Kingston NY. Too bad. I may have to get some cans of race fuel to test the No ethanol theory.

Not the issue here as it dies before i even attempt to let the clutch out. I'm simply bliping the throttle to get rpm up so I can begin to let the clutch out.

Fuel filter? This has never happened to me. I don't like E10 moonshine in my gas, but my understanding is the engines are programmed for that.

Maybe try the Booster Plug or Accelerator Module. The AM is cheaper and it works the same. I bought my AM direct from the overseas source. Only took a week or so to get here. I bought the "compact" model and it works fine. http://www.sol2.be/Performance/ENG/Home/index.html

Mine will occasionally backfire when blipping the throttle but it does not stall. Just more like a cough. Pretty rare, but it does it and has since I bought it. I stalled the bike twice at the dealer when I went to drive away the first time I was on the bike. A little embarrassing.
