Many thanks for all the great responses.
Another one, am i looking at loosening the rear wheel so as to get the chain master link to re-fit? I'm wary of doing so just because i've never messed with those rear wheel adjusting cams before!
@Chasfield
Yes i've heard that boiling thing still being done here in Punjab, India. But maybe they've never heard of a proper Chain Lube!? I've been a happy camper since I switched to Chain Lube from Grease/ Gear oil and what not.
@Edward
Lots of time on hand as i rarely drive the Enfield these days. Yes i do plan to immerse it in diesel to break the grime , old Lube and REALLY clean it. I like the chain to be silent and a really clean chain with free moving rollers will be the first step to it.
Best Regards,
Sunny.
