before you say check the forum I went through 53 pages and I couldn’t find a thread similar. Over the summer I had installed, kuryakyn crusher maverick air filters, vel pro short exhaust and iridium plugs. Also recently had put on a borrowed fi2000 tuner . Recently I’ve experianced losses of power . I’ve noticed that in different gears and speeds it looses revs momentarily then goes back to normal. On my latest ride it happened most of the ride for about 90 minutes. My knowledge is minimal and I’m thinking possibly a fuel blockage maybe , while I’m riding I can feel it loose power for a sec then the power goes back to normal , it seems to fade in and out. The fi light has come in lately and the error code says nil errors. Your advice is greatly appreciated .
