-Vance & Hines slip-ons with packing removed but baffles still in mufflers.
-stock air intake system
Front sparkplug is reddish/maroon. Back plug is clean/grey.
Exhaust pops/cracks when backing off throttle.
AIS system is unmodified.
Too lean?
Plug the AIS?
Didn't put any StaBil in it last winter. Had a stuck float when I tried to start it this spring. Put Sea Foam in it after I got it started.
