Thanks for you responses. It's in the shop getting a diagnosis. Let you know what I find out.
Let's start an oil thread! :histericaOK, here it is.
The Lucas synthetic in the FD boiled riding across the states with trailer. When that happened it turned the oil thick and the increased pressure caused a mist to come out the top valve. This explanation along with much more came from a guy with 25 years in oil industry. Two guys couldn't find any issues with final drive, looks solid. Two days working on bike with two fluid changes and only charged me $100. I had to make sure it was a BMW shop. So I'm riding it and am watching.
I've riden it about 1000 miles in the past couple days with no problems. Any comments?
Prior to getting the LT, all of my other bikes had chain drive. I liked the thought of never having to adjust and lube the chain and carry around a spare master link and chain breaker. In college, I carpooled with a former Harley rider - he had dropped his bike and his thumb went through the sprocket. FD's still have their advantages... :corn:Update.
I was riding through Las Vegas and the rear wheel now could be wiggled at 3 and 9 so took it to the local dealer. Sure enough, like I told the guys in California, needed rebuild including tapered roller bearing and needle sleeves. Also needed a housing cover ($323). So, hopefully good for another 85k miles. The price on the rebuild actually came down from 4 years ago. My bikes now, beside this one, are chain. Easy to replace and can carry a spare with me.
The 99 FD will have the speed sensor hole that will have to be plugged because it is not used on the 03.129K 03, final drive is terminal, wheel wobbles and makes weeky weeky noise on the center stand, feels like going over tar strips when (last) ridden. AFAICT ridden K's of miles after it started to fail (flipper PO). bought a used FD, 99 @67K "looks good" LOL, Is there anything I c(sh)ould do, look at, on the used unit before swapping it in? Are there any good FD remove/replace how to's?
Funny "some internet guy" told me I couldn't use an 05 FD for sale locally because I needed the hole. Then the "99" final drive I got from Canada didn't have the hole... So it all worked out and the FD seems to be all better now. Won't know for sure til the gusher front brake line is replaced (there's a thread) So I can rack up a few miles. Rockerbox next weekend!The 99 FD will have the speed sensor hole that will have to be plugged because it is not used on the 03.
