R850R gearbox changes

[pc-uk007]

Hi,So many questions to ask sorry, I have had a really good ride of my new investment today and I have found gear changes are a bit clunky also when I try to change into first gear from second gear moving along it grinds but stationary it goes in no problem,

Do I change gearbox oil if so what oil grade??or is this normal and first gear has to be only used when stationary ??

I think the 850 has a cable clutch (my 1150 is hydraulic), if so I would start here with re-adjustment before looking at more expensive options.

1st gear is way to low to need when going along or cornering so why select it when moving - if you are slowing down by the time you'd need 1st your brakes will stop you.

I also found my 1100S and ST 1200st have the same issue so I just don't select 1st when on the move unless I can help it. When coming to a stop just snick it into neutral and then select 1st when you are ready to move off.

p.s. I have found that fully synthetic gearbox oil seems to work well with the BMW box of neutrals

I have spoken to previous owners at my t bar and it looks as clunky gear changes are normal for these boxes so may it maybe normal thanks for input and will check clutch cable for adjustment.

Thank you for help with oil recommendations I have ordered 75w90 semi synthetic oil for winter use in my final drive unit and the five speed gearbox with intentions of changing it to 90 SAE oil for summer use and 20w50 mineral oil for my engine for winter and summer use.

Just a update of 75w90 GL5 oil I have been using over the past few weeks in my 5 speed gearbox, I have found my gearbox slipping out of first gear into neutral when pulling away from rest so have drained this oil from gearbox and refilled with SAE 90 GL5 oil, I do not have this issue with slipping out of gear any longer and the other gear changes do not seem to be so clunky either, I have now also changed the oil in final drive unit as well to SAE 90 GL5.
