I went to the street legals last night to do some testing for tomorrow and I had a miss off the line bad at first and better as the night went on.
I don't know the exact weather conditions but it was hotter than the previous races and probably a lightly more humid.
I pulled a couple plugs after the second run to find them showing a lean condition,I would have thought rich with the air we had and the last time they were almost pefect.
I didn't have any jets to try so I put my exhaust back on to see if it made a difference and it did barely had a miss but it was still there and the plugs looked a little better.
I have a 850 Holley AED with the extensions or the rear,my jets are 70 in the front and 82 in the rear.
My question after all this is do I richen both frt and rear or just the rear and by how much.TKS
