RE: Weird lurching/stuttering...hard to describe... - 3

I don't have a hint of surging on my stock 2016 RS, built in May 2015. Perhaps it was designed to meet Euro 3, instead of Euro 4, and that is the difference?

I found the 'lurching' on my bike barely noticeable and simply not an issue. I've owned other FI bikes where it really was bad. VFR1200F and a Buell 1125 CR come to mind....

try an ECU tune (my Hilltop tune has diminished my small jerkiness almost completely)

Thanks for the info @Sanemancured - very interesting. I wasn't familiar with Hilltop Motorcycles, but I've scanned the forum and found information on them and what they do - and read of the positive results. I'm in the USA, but will ask MAX BMW if they can do anything.

@skinneroo I hadn't noticed you'd recently started a "Hunting" topic that already had some responses - seems we're not alone with the issue...

Some great information in here - thanks all.

I think the mention of cruse control was for you to try activating it and see if the bike still surged whilst on cruse. If the issue wasn’t present when using the cruse it could possibly indicate a throttle potentiometer problem or problem with the throttle electrical connection.

Interesting finding this thread as I just purchased my RS and it has the same problem as the OP. Any links to this booster plug?

I cured the issues with my RS by fitting a booster plug, 2 minutes to fit and transformed bike, smooth as silk after.

Has anyone heard of this mod compared to booster plugs?

I can´t share the link so it´s called BMSX Lambda-Shifting (AF-XIED) .

Anyone?

thanks

Do you have a link?

...or Accelerator Module

I have the AF-XIED unit on my 2004 R1150RT which was having fueling problems. It has sorted them out very well. The thing I liked about this solution compared to a Booster Plug was the ability to "tune" the settings on the bike to precisely get the required result. I understand that the R1200/1250RS machines need 2 of the units as there are 2 lambda sensors to deal with so cost may be an issue.

I suggest for disengaging cruise you try twisting the throttle (on, positive, more gas) to an extent that "you have control" only just. Then touch the clutch and I mean just touch the clutch and the bike will drop out of cruise. You wont feel a thing.

My '16 is one of the smoothest fuel injected bikes I've ridden, but does have the slightest hunting under certain conditions. According to the link, if the Accelerator Module is only working in closed loop mode, it doesn't actually address when most of the lean surging occurs. At neutral, or "cruising throttle", as the website states.
