thanks to the encouragement and tips i received here last month, i\ncompleted the drive shaft and clutch spline lubes without a hitch. so i\nthought i'd push my luck with some questions about the front suspension\non my '92 k75s.\n\ni've mentioned before that it takes bumps remarkably hard (even bottoming\nout at times, i believe.) according to the records of the guy who had\nthe thing before i did, he had the fork springs (along with the seals,\nspacers, et al) changed a little less than a year ago and the bike's been\nridden less than a thousand miles since.\n\nper advice offered here previously, i'd like to start the troubleshooting\nby changing the fork oil. unfortunately i've noticed that the thing is\nleaking oil onto both forks at the top of the sliders. so i feel like i\nought to replace the fork oil seals before changing the oil.\n\nfurther complicating things, the leak and the rough handling are making\nme wonder if the mechanic installed the forks correctly. this and\nprevious events with different shops have brought me to the point where,\nunless i do the work myself, i'll be plagued with doubts that the work\nhas been done right. so now i'm thinking about dismantling, inspecting,\nand reinstalling the forks.\n\nproblem is, i don't know what the hell i'm doing. i've taken a cursory\nlook at the clymer's guide and gathered the impression that it's not too\ncomplicated. on the other hand, i also looked at randy g's fork\nalignment treatise (see Duane Ausherman's BMW website,) and it convinced\nme that i have neither the facilities, tools, nor know-how for the job.\n\nin any event, my goals are (a) to make sure the forks are assembled and\noperating correctly, (b) to change the fork oil, and (c) to change the\nfork oil seals. with that in my mind, here are my questions:\n\n#1: if i take the forks off the bike, how difficult is it to get them\nback on properly? i don't understand or have the tools to do all that i\nsaw in randy g's patient, well organized explanation. should i just take\nit in to a new mechanic? if so, can you recommend someone in san\nfrancisco?\n\n#2: in case you encourage me to do this myself, what oil should i use?\nare they any parts (other than the oil seals) i ought to replace while\ni'm there.\n\n#3: any other tips?\n\nalso: i should probably have mentioned that i'm not sure if the forks\nare stock or aftermarket.\n\nall input appreciated.
