I'd leave them at .045, as the electrodes wear the gap gets larger. .045 will be trouble free, anymore than .045 isn't going to increase power.
Age old question
My combo below is running real strong!!About 1,000 miles on engine.Did a little tuning yesterday and it feels better than ever.I am going to replace plugs today.It seems to like the r44t and I have them gapped at a tight .045(hei ignition).Wondering if I should chage gap a little or stick with what I have??:thumbsup:Thanks
