Thank you guys for the very quick responses! I was outside just now, removed the TCI box, opened it up and there was a broken connection very similar to that causing the E4 error code! I re-soldered it, put it all back together and now the bike runs like a champ! I did not see any other issues on in the TCI that I could tell.

Hello all, last fall I purchased a brand new used 1986 Venture Royale, I put about 500 miles on it before the weather forced me to put it away for the winter. As I was putting away for the winter, I fired it up and it was running very rough. Lots of backfires (inake and exhaust backfires) and chugging, as well as the tachometer was not working. I decided to worry about it in the spring because I had too many other projects to do. Well here I am in the spring and trying to figure this one out. The bike never had this problem before. When the engine is running below about 1500 RPM, the two cylinders on the left side have no spark and the tach does not work. when the engine revs up above 1500 the two left side cylinders jump back to life as does the tachometer and the bike runs well. I am stumped, I looked for any loose or corroded wires but could not find any, the coils checked out OK with my multi-meter. Does anyone have any incite on how to track down the problem or what it might be?
