I have a 2013 GT abd I'm worried now! As there isn't a manual available for this bike yet, where would I find out how to change mine? Not sure about what tension to set it or does the tensioner automatically do this, also torque settings etc?
How much are the reynolds chains please? Thanks

Rattlebattle, it was whilst doing an oil & filter change that I discovered the broken chain roller, so the oil was already drained when I removed the clutch cover. Therefore only a small amount came out, easily mopped up with an old t-shirt.

Thanks KC1961; I guess I'll have to risk losing a fair bit of oil if, as I suspect, the crankcase has interconnected passages. Oh well. Smudger: The manual for the C5 etc would do, though to be honest it's pretty straightforward. Torque values for engine crankshaft nut and clutch centre nut are 4.8 and 4.2 KG-M respectively. Chain tensioner is automatic - I wish it were manual. My chain is really taut, or so it seems through the inspection cover. It may be slacker in the middle of its run. I'll find out when I remove the cover. BTW I wouldn't say that primary chain breakage is endemic, but it does occur. Going by the seriously awful original rear chain on my C5, now changed for a Renolds, I just feel happier changing my primary chain. Roger Slater did the same - there is no make on it and I suspect that the metallurgy isn't what it should be. Hitchcocks charge £40+VAT and postage for a Renolds but they do a cheaper one. I prefer to stick with what I know. Your choice.

Forgot to say: no need to dismantle the clutch itself just to replace the primary chain.

Link didn't work for me. No matter, I did the job this morning. It was simple enough. My 2015 C5 had no gasket either, though I elected to fit one, hopefully reusable having greased both sides. Should be quicker next time now that I won't have to fish out all the silicone. I used a length of dowel to knock off the chain case from the r/h side of the bike, using the tab on the bottom rear - the only one I can see can be used for this purpose without a lot of dismantling. I also used the tool that screws into the chain case, though that isn't really needed. I found the clutch centre holding tool really useful in undoing the sprang nut and clutch centre nut and torquing them up again. My sprag nut had thread lock on it so I used some on reassembly. I found that it's unnecessary to drain the oil to do this job. I put the l/h main stand foot on a piece of wood so that the bike leaned a little to the right. Although oil came out very little passes through the holes between the inner chain case and the crankcase. It's a mystery to me how two bits of chain roller found their way to the magnetic sump. I found it easier to remove the pivot bolt at the front of the tensioner, as it wasn't clear to me how the tension should be removed once the nut and spring have been removed. It is now, but I'd probably do the same again. Although my chain was fine I now have peace of mind, especially given the awful rear chain originally on my bike. I gave the bike a brief test run - no oil leaks and a bit of a bonus in that the gear lever and footrest are now better positioned for my foot. Job done. I have to say I was impressed with the cleanliness inside the chain case and with the design and condition of the clutch.

Thanks Adrian, I looked at the video after I'd done the job. I have to say that there are a few points to make. There is no need to remove the side stand or to detach the clutch cable from the chaincase. I would never use a screwdriver to lever off the chain case. Like I said earlier, a long wooden dowel inserted from the other side of the bike can be used to shock free the chain case using the tab on the bottom rear of the cover. If, like me, you don't have a power driver then you're going to have to lock the clutch to prevent the clutch and sprag sprocket from turning. I used the proper tool, but you could put it in gear and stand on the rear brake. Personally I wouldn't use a power driver on the nyloc nut in the clutch centre anyway; I can't see that it would be a good idea to reuse it having spun it off at high speed. What a grotty looking bike; mine was much cleaner inside and out. Don't go much on wearing fibre gloves either - no wonder those of us who do the first few oil changes ourselves find fluff, rags etc in the sump......

Renolds chain and gasket arrived today. Hopefully find a couple of hours sometime soon to do the necessary.
