Re: Top end
Now that you have a fresh top end I would run through the jetting guide and disregard that plug. Get it jetted right and do some plug chops to really know how things are.

Re: Top end
It was a brand new plug as well . Yes I should do a couple chop test... but it doesn't look lean does it.
