Oil Breather XT660Z Tenere 2008 Model
 

Anyone replaced this themselves? Having difficulties on the exhaust side (without removing the front end of the exhaust) and was wondering whether there's an easier approach. Once it's unclipped looks a tight squeeze to swap it out. I've had enough of draining oil from long motorway trips. Any help appreciated.

I never had mine done by the dealer and have never bothered to do it myself due to it being a pig of a job (as you have discovered). I just extended the pipe so as I can tuck it under the bash plate. This has the double effect of stopping the bung being pulled out off-road and it holds nearly four times as much oil (before it reaches air box level).
