Crawgator Finally had time to work on bike this weekend. I pulled brake calipers and removed pads and checked. Plenty of meat left in all of them. They hardly look worn. I cleaned calipers and the pins with brake cleaner. Lubed pins with anti seize and coated the back of pads with anti squeal and reassembled. I flushed per Jim's excellent DVD's. Tested using GS911 brake bleed test and the rear failed. Bled the circuit and the calipers again. This time I got them to pass but I had to really push HARD on the rear brake pedal. Front passed as well but I had to pull lever really hard to get it to pass.
Took for a test spin. Fronts grab hard and fast with little movement. Rear you have to depress the brake pedal quite a ways but at the end of a long downward foot pedal stroke it will grab hard enough to skid and engage ABS. So my question is, should I have to push that far down on rear brake to get it to grab hard? It begins to slow a bit as soon as you engage but to get it to stop you have to almost bottom out the foot pedal.

First time I changed the fluid, I bought a bottle of LiquiMoly fluid from Beemer Boneyard (along with their special funnel); it was 1/2 liter or just a bit more than a pint. It was just barely enough. Second change, I just picked up a quart of fluid at the local Advance Auto store. I probably used a bit more than half of it. So I have a bit less than a pint of leftover fluid that will not be any good in two years... but that quart at Advance Auto was cheaper than the three six-ounce bottles the local bike shop wanted to sell me...

BTW... if you do not have this funnel, you can fake it with a regular funnel and some black tape, but the BeemerBoneyard item does make the fluid change a bit more pleasant.

This 05 has a float. I just got home a few minutes ago. Last time I cranked was around 10 am today. I turned on, let it cycle thru and hit the starter. It started right up with a bit of a stumble on idle. Blip throttle slightly and it smoothed out. Progress! Maybe the Pure gas, Seafoam and Techron fuel injector cleaner cocktail is breaking up whatever minor varnish may have been in the motor.

Then turn key off and back on and repeat and it fires right up after that. It has a bit of a rough idle for about 3 seconds then smooths out. I plan to try and flush the brakes today then I'll take it for a short ride and give it a chance to heat up easy.
i think my issues with the bike was i failed to let it cycle thru before i started it....

if that is a model ModuleMasters works on. I would give them a call to be sure.
also, does this bike have a float or the dreaded fuel strip?
and was the 05 GS out of the woods for clutch splines??

Crawgator Thanks! Both of the front calipers have bleeders so good to go there. How much fluid did you use in changing? I have one pint but Jim's vids say 2 so I plan to pick up another pint today.

BTW, there may be a "grub screw" in one of the front calipers instead of a bleeder. Apparently they came from the factory that way (something to do with how the system was initially filled). Almost everybody removes the grub screw and replaces it with a bleeder as part of the first flush... if you find the grub screw in there, it might be indicate the previous owner(s) never flushed the brake system... ugh...

I'd forgotten about that. FWIW my May 2005 build GS had real bleeders, not grub screws. It may be only the earliest bikes that didn't get bleeders.
