I have a super noob question. Changing spark plugs. Pulled old plugs....very black. Also giant gap about .055.

Replaced plugs. Made a .040 gap and ran it about 30 miles. Pulled plugs to see, still pitch black.

Before I bought it the dealership had to install baffles so it could pass inspection. Could the carb be set up for the stock pipes without baffles? Could that cause it to be rich enough to completely blacken spark plugs after 30 miles?

Would installing new pipes like Bassani pro street for example counteract the richness or compound it. Rejetting is a little too far outside my wrenching abilities. Not to mention a 2hr labor minimum quote.

Is there anywhere I might find some suggestions for rejet sizes/set up etc?

 

well if the carb was setup for open pipes and then you added baffles, it could do that. however, it is an easy test to pull the baffles and see if the color restores itself. as far as jetting, not a big deal and can be done on the machine. the question is what range is it rich in. i always start at the wot since it is the easiest and does not effect mid/low. then set the low side as it has to transition to the mid so you are fooling with the pilot jet and air (sometimes fuel/carb dependent) screw. once it idles right and will respond to blips, then the usually the tricky one, mid where you play with the needle. if you know the carb you have, high chances are there is a tuning manual on the net for it.
not a bad process only time consuming sometimes.

 

Jets can be changed in 5-10 minutes. 4 screws on the bottom of the float bowl. Remove jet(s) in there with a flat blade screwdriver. Thread in new jet(s), replace 4 float bowl screws with allen head bolts. Done. Im sure there's a youtube video on how to.

 

I just took of the kuryakyn hypercharger and it was pitch black. Whole inside and behind air filter. Air filter had alot of chunks in the valleys
