What do you think?

Raising ignition timing can increase spark plug tip temperatures by 150-220 degrees.

NOBODY has asked to see a plug. I'm amazed at the belief that timing it picked off of guesses and butt feedback. That's why I asked WHY the timing is at +7. If you don't understand WHY it's set at +7….then find out or learn.

Advancing timing more and more doesn't make more power. Eventually all it does is create HEAT. Don't fall into the "More is better" line of thinking. Plus advancing timing actually makes the mixture leaner. You might find more power and throttle response with lower timing and going down a main jet size.

But there is WAY more to this topic than can be easily and quickly answered.

 

Your PLUG tells you what your timing needs to be, not your friends, not your manual, not us internet advisors. Till you read up on plug reading, you won't KNOW what your timing needs to be. +4 is safe because it's not a radical advance. +7 is nearly doubling what most consider a safe step up. 

Running +4 is possible on almost any Banshee motor, but moving into the +7 to +10 range requires being VERY in tune with your motors personality and needs. 

If you can "Feel" or "Hear" that your timing is too high……it's usually too late.
