Noisey gear change

[James Embrey]

Ok new here so may be this has been well covered. My bike seems noisey when changing down into 2nd and louder again when down into 1st. Feels ok but alittle stone age. Never misses or jumps out of gear, bike is 56 plate with 10500 miles on clock.

Any suggestions?

Hi James, all normal, it's quite an agricultural gearbox.

You can change the oil to redline shockproof, which quiets it a little, but totally unnecesscary.

change down into second later

i very rarely have to select 1st on the move.

As they say, "they all do that mate". It should improve once the bike is run in, at about 35,000 miles.

Cheers guys. Sounds alittle cold lorry gear box when you get 1st but if thats the norm no worries.

Hi James,
I experienced the same, mainly when the gearbox was well temperated after some driving.
I found a recommendation to change to a oil with higher viscosity in hot condition and filled in Castrols MTX 75W-140 which complies with all BMW requirements. I do belive the original fill is 80W-90.
Switching gear became significantly more smooth in warm condition, also downwards. I hope its better for gearbox, it definetively is for the peace for my mind!
One more aspect that might be right or wrong (would appreciate others oppinions on that):
Lot of gearboxes have shown oil leaks towards the clutch which triggers a very comprehensive (and costly if not covered by warranty) repair.
I tend to believe that such leak would most likely occure when everything is at working temperature the oil is much thinner than at ambient temp. and there might even be over pressure in the gear box (not shure if there is a breaher).
I would expect that an oil that maintains its viscosity at working temp. (not getting too thin) should be less likely to leak through.
This make me believe that my gearbox is better off with the 75W-140.
