Got my maxi tuned and running great. While I was out riding, I heard a sound similar to “backfire” followed by a power loss. Now, I can’t get it to idle and it only tops out around 20mph. Before this I have a clean chocolate brown plug and a smooth idle. Here’s what I’ve done troubleshooting wise:
Adjusted needle (and then back)
Reseated the plug wire
Confirmed correct timing
Is this a bad coil or something else?
Thank you in advance!
