I have a 2018 SE model. I have an SYA snorkel kit installed and tested for leaks. I replaced my factory exhaust tip to a 2R tip to help with the excessive heat in the side plastic from the exhaust. I know these machines run lean from what I’ve read and have a issue with idle stalls and low speed stalls. The stalls have become more frequent and the machine won’t start on the first attempt since the exhaust tip change. I would only stall on start up with factory tip when it was <38* outside before. So I put her in deep water over the racks almost covering the center storage compartment and she stalled within seconds of the pipe under water. I don’t believe the “it happened because it’s a single cylinder” story because the Honda’s can idle under water no issue. Any ideas on why it stalled so quick? Would getting a fuel optimizer be the fix? I love how it sounds and how much cooler it runs so I really wanna fix this. Thanks to all for any ideas/guidance.
