A couple of months ago I bought my first bike. Its a 2021 Suzuki Sv 650 abs. I've loved the bike since owing it and have ridden it very often. However I believe I messed up. I have not really liked the sound of the exhaust. In my mind I thought it would be a good idea to take the muffler off of it to hear what that engine sounds like without being silenced by the factory muffler. Granted the fact I thought it sounded good and rode it around town for a day or two like that. Talking to a co worker about it, he made mention of and or asked me if I noticed a lack of performance, backfiring, etc. I did a little research and learned of the con's of removing the muffler. So I decided to put it back on. Well yesterday my brother stopped by while I was at work and took my bike out for a ride. I got a call from him saying the check engine light was on. When I got home it was indeed on with the FI code showing in the odometer area. I did a bit of looking around on the internet to try and solve this but all I can come up with is using a jumper wire to put the bike in dealer mode to find the code, buy the dealer mode tool, take it to the dealer and explain the already embarrassing story to them, etc. Has anyone ever experienced what I've done and or how did you go about fixing the issue. Also, in the future it I decide to go for a different slip-on muffler, will I encounter the FI code again ?
