"... It felt tiny between my legs.. Didn't seem very powerful at all... :confused:"

Oh dear............... :D
 
This is a very interesting thread.

Three weeks ago my 1200 had it's 6000 mile service and the annual inspection. Since then it has had a similar jerky on and off throttle response. It is really very difficult to ride smoothly in traffic in low gears between 2000 to 3200 rpm. This is all since the service. I know it had a software update to cure the battery going flat. I wonder whether it also altered the fuel mapping. The only other thought is that the mechanic cocked up the throttle sync. I don't suppose anyone has figured a way to defeat the throttle stepper motors without having access to the BMW handheld computer thingy??

thanks to Norman Nleader for his "how to ride2 lesson" :rolleyes: NO I'm not "Coasting" into roundabouts, that's not how the AIM taught me! The problem appears, between all low speed gear changes as you roll off and then try to roll back on the gas. When you're gassing it, it's not so noticable.

Happy to hear it! Your use of the phrase "going into roundabouts on the over-run and then applying the gas" clearly wasn't what you meant, then...

You shouldn't blame me for trying to be helpful. Even people with IAM test passes (gosh!) can have something to learn, sometimes, eh?

Back to the throttle response. If people out there really do have problems, then you really do have problems. I don't. I didn't detect any difference between the 1200 and my old 1150, either. I'd like my throttle to be just as responsive but with a shorter twist required from off to full on.

Cheers, Norman
 
I was concious of this on my home last night - I've started using the clutch continually at low speed - 1st to 2nd gear usually when filtering through traffic.

There's just no way to smoothly roll off the throttle at low speed, so i slip the clutch.

mmm...

Mmmmm........ I 'feather' my clutch at low speeds in first gear when filtering through traffic but this is NOT due to snatchy or surging fuelling - I am really happy with the fuelling on my bike.

It is because of the (IMVHO) slightly too tall first gear and the transmission back lash from the shaft.

It does sound like some peeps here do have issues with set up but I wonder how many people have been used to chain drive and smoooooooth multi cylinder engines and are trying to apply the same riding tecniques to a shaft driven boxer - just a thought :nenau

yeah - you may well be right, it does feel like drive line snatch as much as fueling. You could roll on and off the throttle on my vtr without any jerkiness whatsoever, while the 1150GS wasnt so bad.

Maybe its down to less weight and perhaps a few bikes with above average crashy drivelines? How do they damp shaft drives anyway? do they have the equivalent of cush drive rubbers as on chain driven bikes?

I agree, I've come down the twin route for the last 10 years, Harleys, Ducati's ect.
I find the 1200gs's slightly snatchy low speed drive normal, you should try my last M900 if you want to know what a sharp low speed throttle respose is, and even that was a baby compared to a supercharged triumph twin I had :eek: or the 960 Norton Commando, with 36mm Mikuni's and 11+ to 1 Comp ratio, home made cams and a Q/A throttle :eek These last two bikes were real old school "hot rod" style bikes, over powered, crap brakes, built in a garage reliability :( When I sold the Norton the guy could'nt even kick it over :rolleyes:

Bikes Eh!

Not me sir! I'm off 3 x 1100gs's & 2 x 1150GS's, so I'm seasoned as far as the "Drive Snatch" goes, though this 1200 is MUCH worse.

The feathering clutch thing is a subconscious work-around for a jerky bike, surely? :nenau

Try it . . . . everyone, on your next ride out. try to roll your gas on, nice and smoothly at low speeds, change gear without giving it a handfull. Maybe it's possible to work-around feathering the clutch or a big hand of throttle but personally, I never got used to it on my XR600 after 12 years of riding them. I HATE IT :spitfire

As you say, yes it is subconcious.

Think I'll take up your suggestion just for a laugh to see what it'll be like :D

Oh, and if you think your XR was snatchy you should have tried my last bike, an over bored race tuned CCM - having said that, even that bike would trickle through traffic ok(ish) with the 'subconcious' clutch feathering :D

I find that slow speed (~10mph) riding in traffic is pretty taxing on the 1200GS - the throttle has a very on/off feel from fully closed to just opening. It is just the way it is - slipping the clutch in first gear is essential to smooth slow speed riding on this bike.

It would be nice if the fuelling could be tweaked in some way to smooth the on/off feel out. It is as if the injectors go from no fuel at all to a wee bit to much just as the throttle comes off the end stop.
 
I find myself wondering....

Are those of you with throttle jerkiness issues up to date with "software updates" and recalls?

Have owned a variety of chain and shaft drive bikes and NEVER had any issues with throttle response on any of the 3 shaft drives, 2 of which were 12GS.

I filter pretty much all the way to work and all the way back, through the big smoke (less congestion in the zone MYARSE!) and find the 12GS a doddle to manoevre at very low speeds - even for a short bloke tippytoeing when stationary!

Just a thought....

Relativity

Its all relative - Aint it? :nenau

I mean, if you have just got off a nice, tame cruiser :ymca or something then it might be a bit snatchy :D

If you have just got off a sports bike, then its quite tame :bounce1

I for one, find the GS really easy in traffic (compared to my 600 sports bike) and if you want to ride slowly, use your clutch and the rear brake.

Just my two penny worth. I will get my coat :thumb

The 1200 is certainly abit jerky between off and on throttle, it's not that it's too responsive but it's certainly jerky. More so than many sports bikes (e.g. R1), I think it's just how the bike is and some people have no trouble rding around it, others find it a pain. You have to dip the clutch more than on a 4 cyclinder but then you have to on a Ducati or mille. Mine was a hoorible bike when new, so tight and really really rough but now its loosened up and is a real pleasure to ride, the harder you ride it the better it seems and you just get used to using the clutch a bit more.
 
I just assumed it was my lack of experience on big twins...

I do "pulse and coast" my way out of my twisty turney speed-bump encrusted housing estate as a way of dealing with it though.... (Just a couple hundred feet between several 90 degree turns)..

Mine was fine until first annual service (2500 mile on clock) with battery software update - now I have the jerkiness described...

I agree. See my post further up this thread. My 1200 has just developed this problem after its 6000 mile service and annual inspection. It also had the battery charge software update done. I noticed riding home this evening from work that when completely cold 1/2 bars on the oil temperature readout, it surged horribly as I rolled off the throttle. The revs stayed at 2000 rpm for about five seconds before reducing to 1200 rpm or so. This was declutched in traffic, as I am now declutching at about 20 mph as otherwise the forward surge as the electronics take control of the throttle is very unsettling ;-)

I am thinking of going and talking to the dealer about it.

I would, I've had the same update and, as stated earlier, my fueling is pretty much spot on - sounds like something is not quite right.

Snatching & jerkiness!

This is something I have never noticed and so I thought that today I would really try and make a point of testing it; I covered about 60 miles, poorly surfaced roads, fast busy autoroute, heavy traffic, rain, careful threading through long car park queue ( Foire de Lyon) and back home this afternoon - thinking what a marvellous bike under all these different conditions..........and my verdict? Sorry I forgot all about it, was too busy enjoying myself.
