Re: Brake pad recommendations

Ferodo Platinum FDB2125P Fronts and FDB 2039P are a favourite of mine

Good Stopping Great feel and not terribly expensive and don;t tend to wear out your discs as with Sintered or HH pads

If you still have the ABS Servo operational They can be very hard on rear pads and your fronts will be okay

Re: R1150R - what battery?

Many options but my "Go To" as the Americans say is the Odyssey PC680 A battery "shop" will be able to sort you out "BUT" beware of the Golf cart batteries They do work okay if they are 22 amp, but struggle at 20 amp and don't even bother with the 18 Upi may have to modify the connections to match too

Re: Friction plate wear rate

Exactly as you have described ! Length of a Parcel tying Medium?

If you are doing lots of Urban riding / commuting it will wear out faster with all the start and stops, against doing long runs in the country side

If you have doubts about it Then just change it for peace of mind

Re: K1100rs rear diff

Final Drive My preferred choice is 85W140 something nice and heavy like that

There is a paste but its expensive for a tube Optimoly TA I Think

Actually Motorworks sell it of you ask them for spline lube for an Oilhead

Boiling water is best it dissolves and flushes away the salts

Re: Great clutch explanation

The latest fave rave just in case problems are not hard enough to fix is to put the hydraulic slave cylinder around the gearbox input shaft. Any sort of problem at all is a gearbox / engine split. Scania have done this since the 4 series came out "Pull type Clutches" where instead of pushing to com...

Its not far off, The Spring assembly on that example is to the rear of the assembly where as BMW use a spring disc at the front The rod to take the pressure off the assembly passes through the input shaft of the gearbox and is activated by you pulling the lever up on the bars on the BM set up So bas...

Re: Looking after my RS

I’ve heard a dozen times that the rough running is causes by weak mixture at low rpm, and that the John Gemi chip cures that, so isn’t it possible to adjust the TPS so the Motronic thinks the rpm is higher, and thus gives more fuel, or doesn’t it work that simply. YEs you can "Enrich" the mixture a...

It makes very little odds IF I recall correctly the 33/11 is the RS version Give you a little more grunt from the off and teh 33/12 is the LT type touring ratio Those Final drives are pretty universal between the bikes from the first paralever K's to the Oilhead models Only ABS models on Oilheads ha...

What Specification oil Not viscosity did you put in ??

It HAS To be GL5 Spec and not a hybrid GL4 /5 or even worse GL4

I use EP85W140 GL5 in all my BM final drives now
