Just to update the Forum Members, my C5 has magically resorted back to the extra smooth gear shifting all by itself (all I did was ran it really hard one day, more like a drag race bike)
Now I am very happy. You can well understand why I was in dilema whether to "let everything fall in its place" or "go about adjusting everything on the transmission side".
Royal Enfield Bikes are known to go out of sync for no reason and return back to their sweet ways all by themselves. So says my experience with my 7 year old CI engine 350. Lesson learnt don't fix it if it ain't broke......Cheers
