Now, if I can only get my motor tuned right. I was running #6 plugs in my ninja .12 and couldn't get the tune right for the hottest part of the day. Which way should I have tried, #5 or #7? I was leaning out and loosing power. Temp was fine, just no smoke and not much power. I made it a little fatter on the top and bottom which was better but not as great as it was in the morning. Kept going fatter but then just lost power. Thanks for any advice.
