I have resolved my issues with the gearbox. As it seems, it was a question of changing the shifting technique.

Upshifts: preload the gear lever, pull the clutch briefly and the minimum possible (don't pull to the grip) and quickly change gear with throttle closed, all in one swift motion.

Downshifts: slightly blip the throttle before downshifting

Finding N is now easier than ever, but I think this is due to mileage.

Putting into 1st ocasionally clonks, but it's not bothersome to me.

How many miles on the bike now?

Around 3,200 - 3,500 RPM the engine is surging, and it's been like that since the bike was new, especially on 1st and 2nd gear. At first I thought it might be just too low RPM, but it's much less noticeable below that range. Then I though that maybe it's an issue with the throttle and the computer that can't decide whether it's open or closed when it's just slightly cracked open (by around 15 degrees), recently I managed to set the cruse control so the RPM stays in that range and the problem still occurs.
So to the question, is it just the characteristic of the engine having a torque dip in this range and struggling and I'm just paranoid, or is there something wrong ?
Rauven, just wondering whether you took your bike to the dealer and what the outcome was. I posted something yesterday about a similar problem I'm having, where the revs shoot up as if I was pulling in the clutch when I'm throttling up (but without any surge forward, if that makes sense). I've only got 3,200 miles on the bike and it started a few weeks ago, at first only intermittently, but now "reliably" on every ride and nearly every time I go heavy on the throttle ... Haven't had time to go to the dealer yet, but I'm definitely headed there as soon as I can.

This is most definitely NOT normal!!! My bike never surges, never hesitates.....the throttle response is perfectly smooth and predictable at ALL RPM ranges and ALL throttle actions, from snapping it full on to feathering it....in any gear at any speed. (Not counting lugging.)

COMPLAIN VOCIFEROUSLY!!!!

GSW Rev Surging Issues

Thanks for the feedback, Rocky TFS! Before I knew this thread existed, I started a new one yesterday and have heard back from a few kind hearted souls. They think it might be a clutch-related issue. Have to admit I was a bit surprised since I haven't had problems shifting gears or slipping out of gear. Struck me as more of a throttle (fly by wire) issue and a possible hiccup/lag between the time when the throttle was first applied and the electronic response to the transmission. But what do I know?

I've read several earlier posts on this thread about other throttle-related issues, which seem similar to what I'm experiencing, but not exactly the same.

Anyone else have views on throttle vs. clutch as the likely source of the problem, or heard or experienced what I'm dealing with? This is driving me crazy

On the other thread I posted ("Ugghhh - 2014 GSW Issue on Acceleration; Any Ideas?"), roadracer agrees the problem is my clutch, in fact he thinks I have a slipping clutch. What I don't get is why that would happen out of the blue. Come to think of it, this only started happening after I went in to get the engine oil changed at 3K as my dealer recommended. I can't imagine something would have been done then that could be related to the clutch, right? The clutch has its own oil reservoir. Go figure.

Clutch noise on 2014 GSA

A friend's 2014 GSA Adv is making a ticking noise when he pulls the clutch. Any idea on the cause or ways to fix. The dealer took the clutch apart, checked for loose screws, and reassembled and put new oil in but the problem is still the same.

No that sounds about right. Have you ever tried covering any serious distance in Europe. Roadtrips that would hardly leave ink on the map in the US, take days over there.

The clutch is bathed in engine oil, not it's own reservoir.

Wrong oil?

Is it possible the wrong oil was used? Not likely if a BMW dealer but some flavors of synthetic engine oil have friction reducers for better efficiency. These are not motorcycle oils but you should confirm exactly what oil was used as the symptoms you mention could be induced by using automotive oil with an energy efficiency rating.

Older BMWs had a dry cluch...ie not bathed in oil but yours is a wet cluch so oil will affect its operation. Just a thought.

Sure sounds like a slipping clutch to me too. Here's how to tell: Next time it acts like this reduce the throttle in several small increments about a second apart. When the engine returns to the RPM before the supposed slipping occurred and the bike starts to accelerate, increase the throttle in the same small increments a second apart. If you can control the slipping (RPM surges) by this method, you have a slipping clutch, and it's a 95% certainty that the oil change is the culprit. Somebody at the dealer F**** up.

This may not work if surging only happens when cranking throttle wide open, but some variant of this technique will....i.e., larger and faster increments. What you are doing is increasing or decreasing the torque that the clutch feels to find out where the slipping starts and stops. Other possible causes are MOST unlikely to respond to this test.

There is one other possible cause of clutch slipping, and that is if the reservoir is overfilled, but this would have been apparent before 3,000 miles. Old mechanic's rule of thumb: Whatever was changed JUST prior to a problem appearing is always THE most likely reason for the problem.

I have the same issue. Dealer said nothing wrong. I have tried booster plug as well and it doesn't seem to make a difference.
