S&S 97 build heavy dry carbon depoaits on front cylinder
2002 road king EFI with recent S&S 97 ci kit, stock heads, 510 cam. Power commander V installed. Trying to get break in miles on the bike. Front cylinder heavy soot on plug, rear cylinder plug looks normal (tan). No intake leak. Compression is 200 psi on front and 205 on rear. Stumbles on acceleration however seems to be pretty smooth once at 55 mph with the occasional skip during higher mph. Am in the process of changing terminal ends on injectors due to flaky resistance readings when jiggling wires. Runs more like carb than EFI. What else should I be looking at?
