I know. There are different types available. We made them out of stainless steel. I think they were 14mm, but don't pin me on it. The eBay tins are .7mm??
En route to the Bol D'Or in 1980, riding up the coast from Valencia, where I was working at the time, the DID 525HD chain went through the crankcases on my CB750K2 at the Granollers peage, just north of Barcelona. I had no choice but to abandon the bike outside the police station at the toll booths until I could do something with it on our return from the races. My pals were all on Darmahs and SSs, so I pillioned the rest of the way and back again. On the way back I picked up some Devcon, a couple of dishcloths and half a litre of acetone. The chain, I discovered had taken about an inch and a half by an inch of the upper horizontally-split crankcase and half an inch of the lower one. After getting the sprocket off, there was enough room to fish the two crankcase pieces out of the gearbox (with a bit of wire I found in the gutter) through the conveniently large window that had been created. There was also enough room with the sprocket removed to use the acetone on the rags to spotlessly clean the chain grease that had accumulated on the cases for 5 years. A rummage in the bins had the Catalan bobbies out watching this fool who was going to repair his engine with a Coke can after cutting a patch from it with the scissors on his Swiss Army knife! The patch was stuck over the hole using the Devcon and left for an hour or so before starting the engine and letting the heat slowly build, until I felt it would take some revving. 20 minutes or so later, not a drip of oil visible, I reassembled the sprocket, and with spare links I always carried in my toolkit, rejoined the chain and set off for Valencia. The bike was then in daily use until I could get it repaired properly. I use case savers now.
Quick update. Hyper fixed: New Renthal sprockets and Tsubaki Chain (£166), Generator cover (£169), work done by BikersRealm (£220). Very impressed with the service from BikersRealm Ltd. Thanks to Pavey for the recommendation and thanks to the others who posted constructive advice. Cheers, Moses.

It's 1.2mm thick (I have one) - chain will never go through it. £26 for a piece of folded stainless steel is hardly a bargain
