Quick question

[WEEDHOPPER420]

I just ordered a new engine from California motorbikes and the pre-ported head has a pretty nasty looking gouge in the intake port, should I send it back or can I sand it out without screwing up the port work

I’d say send it back any alteration to how tall the ports are will alter how your engine performs

Will it make much of a performance difference if i just run it as it is???
I realize itll restrict the fuel mixture flow somewhat but i wonder if it will be enough for a noticeable difference

It doesn't look like the timing is affected by it

A casting flaw. As long as it doesn't go too deep should be ok. Sort of a bummer paying a good buck for it and it has quality issues like that.
Defiantly make sure there are no rough bits on the edges of the port openings to break the rings.
I guess with the reports about that outfit, you bought it you got it.
If they will replace it you may as well. I think you have 48 hours to make a quality control complaint.

Let us know what the outcome is.

I decided to just go with it. It was a gift from my wife and ive been out of town working so it sat around at least 2 weeks before I even saw it.
Started the new build this morning and its coming along nicely.
