IMO the best spark plug to use is the stock ngk plug has fitted by yamaha. When ive raced with anyother type of plug in freezing cold weather ive had problems with fouling. And when ive changed back all was good to go.

the iridium ones seam to foul easier but last longer if they dont foul.:worthy:

thanks for the reply, I have tried cr8e and cr9e, for supermoto trackdays, I find the cr92 works better at high revs but fouls easier
