Enfield final drive chain issue

[Propellor]

Hi Brendan.  I've already considered that possibility, see above. It's not as easy as it may sound I don't think. Not to do it properly anyhow.  The rear sprocket is mounted on a spigot, which isn't very deep. The front one is held by a nut so moving it outwards would create problems with the nut engaging. Also, placing the sprocket more outboard puts greater load on the bearing.

No, I'm ok with the idea of going back to a non sealed chain. I'd prefer a sealed one, but not at any cost or risk. Cheers for the thought though 👍

No bother, just chewing the fat really! Years back when I had a T140, I used to go for unsealed chains, but have two, so I could swap, wash, and soak in Linklyfe now and then. They used to get a hard life from that bike. Something like the Xbr needs only rare adjusting, and although I am not a big user, I still never take the chsin off to PROPERLY clean it.

Seems an embarrassing mistake for Enfield - I hope they can reconsider sprocket/boss design, or just ensure chains start life FULL of grease if they are buying them as OEM.

Got the OE chain off this aft. Disgusting state. The only free link out of 102 was the split link. That's because the fit of the o rings here was poor enough to let in some of the spray lub.  The rest were all extremely stiff joints. Horrendous. 

Non sealed chain gone on. Larger proportions of links and pins but same overall width.

MZ - probably the best chaincase in the world.
