I put on 14 / 42 at the last change. Renthal (ally)  on the rear and dog's gonads of a Tsubaki chain.....
 However, its a bit noisier that the OEM
 kit, and had me a bit worried, also runs better a tad looser, with help from 
 a Scottoiler seems fine. And I managed to
 get the wrong no. of links ( doh!) but 
 you live and learn. 
 This makes for a very usable gearing for
 daily 80 m. thrash.
