Laverda Dave:
Matt Hull the editor of Classic Bike Guide has spent the last year or two restoring a RS100. Every month there's an update and a how to type feature. He got it back on the road but after a few hundred miles he had the death knock and has had to strip it down again. Problem turned out to be a failed main/big end bearing, something he didn't attend to in the first rebuild as he was told these never give problems!
He's made some home made tools along the way such as puller's etc.
I know it's not the R80 but probably transferable information between the two. Well worth a read & subscription 👍.

There's something about those engines I love,  they look so neat, who'd have guessed they were German.

Hi Dave,
I've had an R65 many years ago and an R100 RT Classic more recently. Engines are virtually bomb-proof - if servicing has not been skimped.  Depending on the year, gearboxes can be troublesome. Not sure of change points but early bikes had a circlip holding a bearing in place.  BM accountants decided it wasn't necessary as the bearing couldn't come off the shaft!  True, BUT it could move and cause bearing failure.  Saved them a few pence on each bike. Many replaced under warranty, so the circlip was refitted and the groove re-introduced.  My 95 R100 had the groove - a friends 88 R80 didn't.  I made a rig for the lathe to re-machine the groove in the hardened shaft with a thin grinding disc in the dremel.  All gearboxes can suffer from gearchange spring failure which leaves you in whichever gear you were in when it failed.  A few special tools needed to strip the box and the casing has to be heated to get everything out.  I made the tools and gave them to the mate with the R80 but could beg them back if you needed them.

Another page on the site that I'd forgotten I had posted - am I getting old?

Thanks Fellahs those are very interesting and helpful replies. I will start reading up on classic bike etc and could be interested in those tools Ian. Impressive that you have the skills and kit to make them. Nothing happening very soon on this but great to know you guys have got my back 👍
