Hi and thank you for your assistance. The bike is a 2001, it has recently had a top end rebuild (small end bearings etc), I have just recently changed the plug, appart from that it is as I bought it. Where will I find the power-valve and how do I check if its working? I will look at the exhaust model when I get home.
Is it right in saying these bikes are one of the quickest, as I cannot stand with a yzf 250 4stroke at the moment!
