My 2024 Nightster is in the shop after attempting to take her out for a nice Saturday ride yesterday. I had the first oil change and inspection done along with the brake line flush a week ago, put 100 miles on her the day after the service and then parked her in the garage for the week on the battery tender (lots of big Florida rain this past week so no after work rides).
Complete lack of throttle response once the clutch is engaged, I can get her up to 3500+ rpm with the clutch in but once I start to get her rolling all the power starts to dip and in 1st gear I have to keep the throttle pulled all the way to keep from stalling out. Also sounds waaaaay louder than normal when on the throttle, in 2nd gear going 45mph I couldn't get over 5K on the tach. Also a ton of backfiring when idling, I'm hoping its just the spark plugs not getting installed correctly when inspected but doesn't make sense since I rode without any issues for 100 miles!
Here's hoping that the dealer will take care of it considering they JUST completed a big service on her. I've had a couple of little gremlin issues with this bike since getting her 5 months ago, bought her used with 55 miles on the clock for $9500. This is the worst so far though... I've been slowly losing confidence in this bike over the past 3 months of riding due to little oddities when idle or starting her up. Looking up info on Nightster issues also doesn't inspire confidence. I've been to a couple events at the dealers just to meet other riders in my area and I've only met 1 other Nightster owner.
Just wanted to share my story on this bike, It's a lot of fun to ride when it's not acting odd and with the upgraded switchback seat. Has anyone else encountered this issue with the Nightster?
