Consequently the timing is more sensitive to what type of gas you're using. If you're using regular (as stated by the Owners manual) stock firing is fine--can verify by strapping it to a dyno and going from there. If you want to adjust timing, you'll need to put it on a dyno (don't go by feel), and slowly adjust it from there. Depending on your spark energy you should see some decent gains (don't forget to go to a higher octane rating when you adjust it).
I understand all that. but, Being as i have a Large Street Ported Motor, Factory timing isn't correct anymore right?
