A while back I made a post asking about NSRs and RGVs..... well I ended up buying a 1994 28SE, and I'm already researching how to get more power out of it. One of the major restrictions seems to be the little rings welded into the headers. How safe/easy is it to grind these out and let the bike breathe a little easier? And what sort of gain could you expect from this mod?

Cheers
