Drain the old fuel out and start fresh. Is sounds to me like bad fuel/water in fuel.

Maybe you should take it to a competent mechanic, instead of guessing.

if it runs crappy after riding in the rain then its prob the spark plug got water inside the little hole. Pull the spark plugs out and dry it out.

If it’s running that bad, or not running at all now, I’d think it would throw a trouble code at some point. Check them and use this for reference.

Make sure you check the wiring into the injectors. Make sure it is long enough and not stretched or kinked or broken.

It can only be so many things. Engines need fuel, air, and spark to run. Has to be one of those issues. Start easy and eliminate. Then move on. You will find it.

ive already drained the gas and put new gas and seafoam in and that didn’t do much. i just checked the spark again and it was pretty weak, barely made my tester light up. this is all started after riding in the rain, someone suggested water was sitting in the ignition wires. when they say ignition wires are they referring to the spark plug wires to the coil? or could the coil itself be bad with less than 5000 miles? it hasn’t thrown the check engine light either
