Vapor lock on my 07

I had my one way valve go bad on my fuel hose, and created a huge bog when landing hard off jumps, and a semi irratic idle

Has anyone else had this? Yea, took the one way off, and it was night and day

Check yours if you have these symtoms

Take the one way valve in the hose that comes out the top of your petrol cap out so it can breath.
