Zitat von Jim Evans im Beitrag #29 Mine did this (smoked briefly on start up, I can't be sure which cylinder it came from  ) before I shortened the side stand. It was after a long motorway cruise and then left on the side stand for a few days. The other time it did it was after I'd shortened the side stand the first time I fired it up after lockdown. |

Zitat von ChrisA im Beitrag #30 I wasn't that comfortable with the lean angle on my 1999 Oilhead RS. In my opinion, it was too extreme. What seal challenge? Do you mean piston rings?

I guess what I am saying is with my 5 prior BMWs I never had a smoking or issue with oil getting past valve stem seals or rings even the R1100 with 80k on it. I don’t re ember the angle of lean on that one, just remember it never seemed to want to tip. I restore old Porsche’s as a hobby and yes some of the earlier 911’s can smoke at start up but if properly rebuilt even the ones without valve stem seals will not smoke, granted in theory they are truly horizontal. If the sole purpose of the near vertical stand position is to eliminate potential oil migration past valves or rings I am surprised. |

Forgot about the rubber isolated handlebars, yeah did not like that either. Did add some weights on the handlebars which helped smooth things out a bit. Found that around 10k miles the bike became smoother and shifted much cleaner. Went from this one to a Ducati ST, which actually was a very reliable bike but some of the engineering stuff drove me nuts. First time adjusting valves was a fun novelty, after that not fun. It was the RS1100 that brought me back to the RS1200. |

I know at some point in K100/1100 production BMW installed pinned piston rings (like a two-stroke) to keep the open end of the piston ring away from the bottom of the cylinder. I don't know if they are still using this method in more modern engines. Once my K100RS embarrassed me by blowing a substantial fog of oil smoke at a group of riding buddies on startup. It had only been sitting on the sidestand for maybe 15 minutes. They insisted I park behind them later. I keep my bikes on the center stands between rides- Makes checking the oil level easier and takes up less space.

Zitat von Mr. 36654 im Beitrag #34 Our 1987 K75Ts smoked like crazy when parked on the sidestand over night. Our 1991 K75Ss did not smoke because BMW pinned the rings or something so the ring gaps did not line up. Maybe a couple times a year our K1200RS would give a little puff of smoke at start up after they sat over night on the sidestand. When camping and the bikes were parked on grass I used the sidestand instead of centerstand. Metal plate placed under the stand.

Zitat von Boxerboy im Beitrag #10 Sorry, I am fairly new to boxers, would you mind to elaborate ? I am currently using the center stand for prolonged parking (when it has to stay more than one night in the same place) or when I park it in a tight spot and don't want to take too much space. Other than that I use the side stand during the day or overnight. Thanks in advance for your explanation.
Ain't no thing like me, except me!

Ah, nothing for you to be concerned about on a wet-head modern boxer. The old Airhead bikes had some poor centre stand designs, the bolts would bend and eventually you would find the weight sitting on both wheels, then lifting the bikes off the centre stand becomes an enormous challenge. |

Well today I became the latest victim of the 'damn kickstand'. KC100->CB100N->CB250RS--------->DL650AL2->R1200RS |

Zitat von Freddyfruitbat im Beitrag #43 Feel your pain. The good news is the plastic bends. If this were the K bike fiberglass, you'd be out a lot of money.... I liked the new sidecase - they're paintable, and I've never owned one I didn't scrape. But cracked? Was this the OEM case?
