Well gave the bike a long 200 mile run culminating with a 25 mile blast home down the motorway. Today took out the plug to check how the bike is running and found the porcelin of the plug was snow white and the electrode had no deposits on it to speak of, this to me flags up running weak. So i gave the fuel mod a tweak and went back on the motorway after numerous trips up and down and adjustments, i have found if I make the mixture more rich the bike vibrates noticeably if i weaken it it runs better but I am not going weaker than my original setting for peace of mind. So after a good ponder i put the original filter and snorkel back on turned the fuel mod off and went for another ride. The result is hand on heart i cannot tell the difference between the stock and DNA set up. so the fuel mod and filter are not going back on. I am however keeping the co2 mod as that did have a noticeable effect on the flexibility at low rpm. I think the yamaha mechanics have richened the mixture at the last service as the tickover was down to 1200rpm from 1500rpm after the service and the performance was much improved. if i richen the mixture via the kev mod it drops more down to 1050 rpm. I think the apparent increase in performance I thought I had was due to me giving it more stick than usual to see what she would do.
