Re: Suddenly running better
Sounds a bit rich.
Also, the 91 octane is a waste of money.
All my builds would pull my 200# up a hill and have some spare power doing it. 44T sprocket, stock baffle.
Finally, you won't see an improvement in performance as far as break-in goes until 250++ miles. Vary the throttle and engine load often, and don't baby it.
