Clunking noise

[ddanby2002]

Hi guys, I'm new to been a tossed but have wisely invested in a gsa 1200 30 year anniversary, awesome bike... Anyhow, I've just noticed that when I'm riding and going down in gears 1st and 2nd sound like I've dropped a tool box, quite a loud knock down, is this normal or am I riding it wrong or what, obviously different to a r1 but does anyone have a clue, don't want to spend a fortune at Alan Jeffries if nowts wrong, cheers lads.

Mine clunks down the gears, like some kind of agricultural contraption.

 

[ddanby2002]

Yep on the 3rd boxer now and its a 13 plate 90th like yours, as they say on here. They all do that sir.

That said its can be very clunky, but if it don't feel right no harm in getting it checked.

Cheers lads, they do seem bullet proof like

While they seem to "all do that", you could, when you change the oil in the gear box next time, put a synthetic 75W-140 GL5 oil in. BMW recommends 80W-90 synthetic GL5.
The -140 oil obviously has a higher viscosity at operating temperature and makes gear changes more smooth and less noise while it does not cure it completely.

Blip the throttle each downward change, reduces scaring pedestrians and clearing pigeons.

Matching the engine and gearbox revs avoids the clunks and crunches. TBH it feels brutal to not throttle blip on downshifts.

The old Diversion 900 was even worse on downshifts but going up was better without the clutch.

Funny that my 13 plate 90th has a smooth as silk box, both up and down the way

That must be due to the extra internal lubrication within the gearbox after laying her down on one side
