So I yanked all 6 of the grills and have 6 1 inch holes now Not sure if that will allow more air in and lean it up from the rich I seem to be running right now, but cannot hurt. I have pictures of the plugs but suffice to say they are all coal black. That with 32-33 MPG means I HAVE to be rich.
I do seem to have a bit more power and a deeper rumble. Also she is start easy as hell. Also seems to be running less enricher to keep going cold.
Odd thing I noticed today was a "bloop" type sound from I believe the rear jug pipe. Hoping that isn't a precursor to SVS
So I guess I'll run a few tanks and check the plugs to see if they are clean or blackening up again. If so I guess I get to go into the carp and look at the jetting.
I am going to fully remove the carb
next weekend and get all the jet sizes and list it all so I have a known starting point.
