Time to own up to being dumb here......using Jo's excellent motion Pro tool to push out a rivet on the old chain, I then attached my new chain and pulled it through. I greased up the joining link...slid on the O rings both sides. All good so far, but when it came to fitting the link plate and split link it just wouldn't fit...no matter how hard I pressed or squeezed. The split link just about fitted on its own. Never had this problem back in 'olden' times!. As the split link looked more substantial than the ones of old, I decided you didn't need the link plate as well so just fitted the split link on its own. ..and I have to say it looked and felt fine. LUCKILY my tiny brain was telling me it's not right, and when I read up I found it was a known hassle with 'O' ring chains and you need to press the side plate on . This I did ....job done! . And the Tenere is so much nicer to ride with a new chain and sprockets! Steve
