I've got a 2002 1150GS with about 47,000 on the clock. I had to bleed the clutch after the banjo on the master came loose and sucked in some air. While bleeding I noticed the fluid was an interesting color in the master reservoir. Usually old fluid is black or clear. Black is water contamination. This was a brown color. Huh. Odd. I found a thread, http://www.advrider.com/forums/showthread.php?t=491635, about bleeding the clutch and his fluid has a similar look to it. OK. I'm guessing this is a no-brainer and the fluid tells the story. But, before I put down some money for parts or give it to the stealer who quoted me over 300 for the job/diagnosis....I want to be sure. Other possible symptoms: Tractor like shifting. Its very "CLUNKY". Meaning each change is a very solid CLUNK when gears are changed. This seams inconsistent and I can smooth it out a bit, but I don't know. I am told the GS has a very "industrial" feel to the shifting mechanism. Shifting. Sometimes it won't find second naturally or will go into neutral instead of first. This may be user error on the latter, but I very deliberately upshift to try and alleviate the issue. POssible "skittering" sound. When hold the clutch in, sometimes I can hear a skittering sound while the bike slows to a hault. I'm new to bike so this may be normal....or it may be the dogs slipping over their holes because the clutch isn't operating correctly. You tell me. I'm not afraid to turn wrenches here...just need to know what direction I'm headed. Thanks.
