I ran the same chain and sprockets for donkeys years with hardly any maintainance or adjustments ever needed. Back end of summer last year, on a whim, I put an S.R.M. belt kit on, after hearing all this I am begining to wonder if I have been wise?
They advise running it in grease so I do just that, but it does seem an odd thing to do!........... It's like their comprehensive engine re-build guarantee, which is only valid if you run it on straight oil and NO filter. I don't understand that either!........... The bike still has a cartridge filter fitted and it would take very little time, effort or cost to plumb it in, but I don't.
I suppose my point is, for every A10/A7 I have built they will have done 100's. So for me, I ask the question and argue my point of view sometimes, but at the end of the day I follow their advice to the letter. Tens of thousands of miles with very little trouble back their views up. For me, adjust it like they say and pack it with grease!
