Rough start with a K1200S (2005)
I'm new to this site and K1200S bikes.
Hmm.. where do I start. BMWs run in our household so I figured why not try a BMW bike this time around so I went with a K1200S. it's got 50k miles on it.
Well...choppy little guy to say the least. Certainly not what I was expecting from the BMW brand.
What I was imagining was a really robust and smooth shifting experience, good road stability and lots more. I am not going to trash it all the way but boy, this is not what I was thinking. LOL
Anyway here's my list of things that I'm hoping you guys can chime in on and perhaps help me get started on where to look and what to attempt to fix/swap:
1. The transmission in neutral is like a bag of loose bolts and nuts. Apparently this is categorical for these bikes but somehow I just can't come to terms with it. There has got to be something that can be done about the stupid clunking noise in neutral that's better when the clutch is in but not entirely gone. also who wants to hold the clutch at every stop for the duration of all traffic lights. Any thoughts? Has anyone actually been able to figure out what's making this noise?
2. Related to that noise, each time I hear the clunking noise in the transmission in neutral, the RPM varies (deeps for noise, comes back up and then over again).
3. It's far from smooth in first gear when slowly accelerating. Very choppy and jerky around 2500-3000rpm range. both in 1st and 2nd gears. there's a good amount of hesitation as if it's gasping for air/fuel. I'm thinking spark plugs, maybe fuel filter, maybe ECU tuning. who knows.
3a. It used to have a remus pipe on it when I bought it and it was backfiring like crazy. No chip installed so I put the stock pipe back on to give it back the backpressure it needs. Much better and way smoother running but it still hear occasional backfiring, which is a bit strange for stock.
3b. Everything is essentially stock on it now. Oil level is good. I haven't done the oil change yet but the oil looks good for now.
4. Related to #1 above, i also feel some inherent vibration around 2500rpm when accelerating in 1st gear. I'd bet my money (at least some of it) that the transmission issue has to do with this vibration feel when accelerating. it's more prominent in 1st gear than elsewhere.
5. Going from 1st gear to neutral seems like a dream come true about 99.999% of the time. The only way I can somehow be certain to hit it most of the time is going into 2nd gear and then tapping it gently into neutral. Compared to other bikes I previously owned, this is just pure nonsense.
i'll stop here as to not overload the post.
I am hoping you guys can kick in with thoughts on 1-5 and I can hopefully start swapping stuff out and repairing what makes sense.
I guess one option is to go and unload cash at a local dealer but I'd prefer to get your thoughts first before dishing out cash for who knows what at the dealer.
I'll call them to find out how much it would be to do a full assessment of it but knowing how they operate, I'd probably have to part ways with at least $300 to find out the basics and perhaps another $1k for them to open up the tranny and tell me that "it's normal". LOL
