I need to replace the chain and sprocket on my 07 R6 and was wondering what a good size is for the front and rear sprockets? By that I mean which sizes will be appropriate for the different tracks here. Will the standard -1,+2 work or is there a better setup? I'm also thinking about going with the Pitbull sprockets, anyone have any issues with these?

Also, I was wondering what are the requirements on safety wiring the bike. I looked through the rule book and didn't find anything, but I could have missed it. There was some discussion about it in another thread but nothing posted up. Can this be made into a sticky?

Thanks!
