Hi Guys,

after getting by Ten ready for my trip in 2 weeks i tried and tested everything just to make sure. In the last couple of days she started to run a bit rough and since yesterday the surging got annoying again. Also in and out of corners is a pain with the bike jerking a lot. So after coming home today i tried to move the sprocket holder forward and back by hand and it easily moves 2mm. (My 86 Ten has the same setup and the same rubbers. When i bought her 7 years ago it had a Kev mod in it. So the issue was already known then! It is still in and works just fine.) I suspect the cush drive is knackered. Problem is she has only done 1900 miles and 5 months of ownership.
Too late to go to a dealer today and i am going to be working away for the next 2 weeks. Only got the Sunday when i am back and leave Monday morning.
Here is the question:

If i temporarily use the Kev mod will it effect the guarantee when i get back to the dealer?

Is 1900 miles a record?

Should i bother with a replacement? The mods seem to last longer anyway.
