I'm a new member looking for a used K. I frequently ride 4,000 mile trips from the west coast to the midwest and have been doing this on a '99 F650 for several years, a lot of the time riding 12-hour days.
Needless to say, I'm in the market for a used K-bike, RS or GT but got a wake-up call yesterday.
I test rode an '01 K1200RS for a couple of hours. There was cosmetic evidence that the bike had been down but I was prepared to live with a few scratches (the price of a new K doesn't even pass the laugh-test). The bike in question had recently received a 24k service and it now has 25.5k on the clock.
When I returned to the dealership, the sales staff showed me their service records. Apart from noting the cosmetic bumps and bruises, there was a notation that said "transmission seam final drive leak". After a conversation, it was deemed a weeping problem, not a leak - hmmm... when you're going to drop $8-9 large on a bike, weeping and leaking is the same thing... right? :wtf
I was told the repair cost could be between $325 and $1000, but the service dept. wouldn't know until they looked at the bike. Good grief, er, why is it on the sales floor? :wtf :wtf
Being a DIY chain and sprockets guy, I went outside and started checking the seals on the drive shaft (not really knowing where to look but giving it a go anyway). I found evidence of a weeping seal on the shaft and, probably because I had ridden the bike for two hours, there was also a small wet-spot on the pavement. Needless to say, this killed the deal and I have to wait a little longer for my classic K.
Based on my limited knowledge of shaft driven machines, I managed to find some online information that sounded similar to my situation but I'm still trying to clarify a few things, so my questions are:
Could the use of synthetic oil damage the seals on an '01 RS?
Does this sound like a bearing problem, meaning is it likely the old 19 ball bearings haven't been replaced with 17?
Is it likely the whole transmission would need replaced?
Thanks, in advance.
