I only have about 400 miles on the new clutch (Barnett) but so far so good. (I'm the guy who did the swap to a barnett pack for a k1200s, same part) I had one slight squak once while it was breaking in, but nothing after. The shifting difference was unbelievable. Almost all of the clunking gone except when its cold, its still somewhat prevalent but no worse than any other bike. I refused to pay 1600 bucks for a clutch pack that was no different than the one I took out that was completely worn at 23k. Some people say poor oiling, some say poor specs, poor material, whatever. I've never replaced a wet clutch on a bike in my entire life. My buddies 03 FJR with 156k on it had a perfect clutch in it.
The entire cost is a little more pricey because you have to go into the side cover again. Too bad the dealer didn't know you were having issues when they installed the jump guard because they were right in there. Another couple hour's labor and you would have had a new clutch. After speaking to the guys at Barnett for an hour, they said the material on the OEM pack is the standard organic material and they chose to put a carbon fiber friction material to make it last longer.
I didn't ride long on the old clutch but I can tell you there is a difference. I purchased the bike used as well. Currently, I'm trying Rotella in the bike. I like the BMW oils and they are usually exceptional, but I trust rotella products and they seem to be happy with my current clutch.
I'm with you on the BMW statement. I've had numerous BMW's, RT's, LT, R's, and I still have my '02 RS that I gave to my sister to ride and she's selling her VFR. BMW certainly went through some growing pains with this engine and clutch. I looked up the company who designed and made the basket and clutch pack. They seems to make everything and it doesn't look like motorcycle clutch packs is their specialty.
Oh well - I'd expect this kinda nonsense from an italian bike manufacturer, not a BMW but s%#t happens. :-)
I think the other issue is that BMW parts prices have always been expensive - but talk about sticker shock when I purchased the 07 GT. Actually, prices are rude. the 07 and up BMW cars are no different either. It was enough for me to choose a Mercedes again over a BMW on the car side. Mercedes hasn't drank the 'kool aid' yet.
1600 dollars for a clutch pack is absolutely uncalled for and the unsung heroes as far as I'm concerned here is Barnett.
