I have always kept my bike in top shape oil changes every 2000miles service every 5000miles but at 18000 miles now it just seems to be loosing power! plug looks realy white and furry but looking at the plug which was last changed its a more richer healthier looking plug. I am running the CR9E instead of the CR8E manual says either one but the last time it was serviced a 8E was put back in! to be fair it has never been right since its last service so any body got any clues I have drained float bowl (which had bits of crud and a slight bubble of water in) and just running out of ideas!! also I run super unleaded any help appreciated.
