I just bought a 2014 Honda trx400x. Rode it Day I bought it. Had a little trouble starting it that day. Next day it wouldn’t start. Not freaking out yet.
Battery is good. Just dumped gas. Hopefully was just old gas. Gonna put new in with sea foam. And gonna get new plug. See if that works.

Couple questions. What is gap on plug? And what else should I check if this doesn’t help?

here is a good place to start, to get information... how sure are you the battery is good?

It was the battery! Just bought a new one and put it in. Didn’t think to check a new battery from the store. Thanks for the help!!

?? Great job.
May have to buy a service manual on the flea so you can tackle all the periodic maintenance but you can use my parts links in my sig block
