I ended up just taking the plunge and getting them. I did a bit of research and their aparently pretty good and at $42 including postage from the US I cant really complain. I was tempted to test out those new pulstar plugs that "claim" to add an extra 10 horse power but somthing about them seems way too gimicy and I read a few stories about them blowing peoples engines up so I thought Id give them a miss. Id love to hear if anybody else has had any experiences with them though
