Need alittle help here guys. Had my bike on the Dyno and for some reason it losses power everytime @ 9000RPM's. The Air Fuel mixture is good, everything looks fine, tried a different coil, computer but for some reason seems to be the same. This problem is just making me draw a blank, need alittle help if anyone else has had the same problems. Also hear a rattling noise in engine on warm up, but after warm up it seems to go away. Im thinking cam chain tensioner is going bad or guides are bad. what you guys think? thanks and hope you all can help.
