Your videos are always well presented. Calm, thorough and with good explanations. For us airheaders and would-be tinkerers, boxer2valve and your collection is the only good sources of video-inspiration that I know of. Looking though the uploads, you didn't visit the inside of the crankcase, looked at bearings, the cylinder studs .. ?
Is that special tool required to push the timing cover on or could you just turn the engine so the timing components are facing up and then push really hard from above? Then when you put in the bolts won't it seat correctly? That tool is just really expensive from cycleworks so I'm trying to figure out if it is required.
Dave, The '76 models have the duplex (double row) chain without the master link, so you have to use a bolt cutter to remove them. The replacement chain I use has a master link. You can order one from Euro MotoElectrics, part# TChain258 and the replacement crankshaft timing sprocket has dual teeth, EME part# TimingSprocket198. The procedure is the same. Here is a document on how I did this for a 1977 RS. brook.reams.me/bmw-motorcycle-rebuilds/1977-bmw-r100rs-rebuild-project-index/11-bmw-1977-r100rs-replace-timing-chain-crankshaft-timing-gear-nose-bearing/

Thank you, 🙂

I love the detail that you go in to. How similar or different to my 76 R100/7 is this? I think I need to replace my timing chain.
