Leanest cyl?
Dont have any idea why but it does.
My #7 went while making a pass spraying last year.
Everything else looked fine and the A/F overall was dead on.
Luckly I had planned on this happening and it was no big deal.
77 bottles on Nitrous on a stock bottom end and I never sprayed less then a 150 shot.
Well at least 77 reciepts of nitrous bought, I probally lost a reciept here or there.
