I've read through some other threads to try and sort this one out but am still quite lost.

I had 2 links taken out of my chain a few weeks back. The chain was well cleaned, the sprockets looked in good order, so this solution was acceptable. I'm not super confident that the 'mechanic' knew what he was doing, but he seemed to put everything back together okay. Due to Carnet complications, I'm now in a sudden rush to get out of India and into Nepal.

Now, the chain seems to be "stretching" at an alarming rate. It goes from snug to slack in 600km, needing an adjustment of 2-4mm each time. I'm almost out of room on the adjusters again.

As was mentioned in previous threads, I started hearing a grinding noise at low speed, but only when the clutch was engaged. When I tightened, and lubed the chain, this noise seemed to go away.

Currently, the slackening/ noise seems to be more constant, and adjusting the tightness/ oiling it doesn't seem to do the trick. I'm 1500km from the Nepal border, will be passing near Calcutta, and NEED to be out of India in 6 days (by the 24th of February)


Questions:

Should I stop in Calcutta for a day and try and sort this out? There are no shops/ knowledge in Calcutta that I know of.

Are motorcycle chains interchangeable?. My biggest question/ most likely fix if it is the chain. Supposedly, Hyosungs, CBR's and some other large bikes are for sale in Calcutta, although last time I was in Calcutta nobody seemed to know what they were talking about with regard to foreign/ big bikes.

Any other thoughts as to what it could be?

Thanks!
