This was my 2nd ride on the bike (10’ Yz250) since a complete rebuild. It did it the 1st actual ride after break in. It got hot and started doing it then. So when we got back home, I checked over the carb boots, reed cage bolts, ignition cover, etc and all were tight.
So yesterday we were riding, 10-15 minutes into the ride it started doing it AGAIN. Wtf?
FYI: We use highest rated octane pump gas mixing between 32:1-36:1. Plenty of oil.
It could be my hearing in my helmet and when the bike is doing it, it sounds almost like a “knocking” type of sound.
The bike while riding I also notice has kind of a lag to it as well. I ride woods and technical stuff so most of my riding is slow cruising/lugging through stuff and up rocks, etc. but when i open it up it “feels” like it doesnt explode like a new bike should especially for a 2 stroke.
What do I do here? Im lost as far as carb and jetting goes and depending on engine stuff...that too.
I have research the surging issue all over google through other known forums and no one seems to have the same problem as me or know of a sure answer as what it is.
