2020 Triglide. Trip from near San Antonio to Big Bend with 6 other bikes. I-10 all the way running 75-80 mph. Just before we turned off I-10 to Fort Davis, trike felt like it was losing power. Got off I-10 and definitely was loss of power when accelerating. Felt like one cylinder wasn’t firing. Once up to speed it ran fine until I tried to accelerate or put a load on bike like going uphill.
My trike had 3100 miles on it at this point. Road the Big Bend area for three days with the trike losing power up every hill or when accelerating. Also, it had a hard time starting every morning. Sounded like it was hitting on one cylinder. Again, at cruising speed, it ran fine.
On trip back home it ran fine at 75-80 until accelerating or pulling up a hill. When the trike cutout, it sounded like running on one cylinder just like when EITMS kicks in. Took bike to dealer when I got home. They had it one day and closed due to virus. Opened again last a Thursday and called to say bike was fixed. I asked what the problem was and they said fouled plugs and not covered under warranty.
Also, Harley Corp is closed down so no talking to them. At this point I had 4110 miles on the trike. I asked which cylinder was fouling out and they said both. So apparently all four plugs were fouling but trike would still run 80 down the interstate without missing until I tried to accelerate or go uphill. They could not give me any reason the plugs would foul at this low mileage and they had discarded the plugs they pulled out. So has anyone had something similar like this happen. I’m just concerned about the same thing happening again in 3000 miles.
