Hi

I have just changed the crankcase to airbox breather. What an unbelievable PIA! "Babies hands" job for the airbox inside and a PIA jubilee to get to. I have lost my flexible jubilee driver so had to find a path to the screw head, which I eventually did. But the pipe ends at some device which I have read about on this forum inside the airbox.

It has one of those stupid single use clips that need prising apart, so guess what, that end isn't attached. It this in any way important? My K100 one was a short length of pipe which took 15 mins to change. This was more like an 1 1/2 hours.

PS No I don't want to deconstruct half the bike or drop the engine out of the frame to get the airbox top off! I have done that once and that was to sell a K11 in bits!!

Cheers
Guy

Found it! It's goes to the Cyclonic Seperator!! Well guess what, it doesn't any more...

the rubber hose from the crankcase was badly cracked so i had to replace it. Whew!! what a job. like you i could NOT get the old one off the cyclone box working through the gap you can get when you raise the cover as much as you can - not bloody much. So, because the hose inside the filter box was ok i cut it and then cut the new hose (after fitting it to the crankcase outlet and putting it through the filter house side) and put a bit of connecting plastic tube (from an old oil container pouring tube!!) between the new hose from the breather outlet and the old hose to the cyclone and jubilee clipped both the ends to the connector tube. that was 2 and a half years ago and last christmas when i did a serious stomachectomy on the bike - clutch etc, another bitch of a job - i found the breather hose set up was still fine. German engineeering at it's best i don't think. Mind you the clutch job really showed the brain power that went into the K11; maintenance, who needs to do that!!
So you have my sympathy, but the job i did stopped the oily vapours that used to waft up from below.
cheers and good luck.

Thanks,

That was my idea too but I was a little frugral in what I left on the cyclonic suckervator so was left with potentially bloody knuckles to get it fitted. I might have the patience on the next filter change. Thanks for the reply on this mystery engineering.

Cheers
