I heard a broken Reed or something would cause it to shut off too that's why I checked that first. I did find the problem though. It was out of gas. When I looked in the tank it had gas but not much. I took the petcock off to clean it and saw how high up the inlet is for when the fuel is on. I never noticed it had to have that much fuel. When I took the Carb off it barely had any fuel in it I'm guessing bc it was only getting fuel when it slowness around enough. I think that's why it wouldn't idle right and seemed like it had an airleak. It was starving for fuel and that caused a lean condition. Does all this sound logical because the reeds were good.
No, broken or damaged reed causes poor starting, general lack of power and messed up jetting, not sudden shut downs.
How do I know? Broke and wore many over the years, just changed reeds in my Blaster this spring (KTM motor).
1/8" worn off corners of a couple carbon Boyesen petals. Poor starting and running rich, idle hard to tune.
Don't worry if the petals are bent up, you will never notice it but you can flip them.
Slight fraying or worn edge is your hint to order new ones, but you can ride them out for the week.
How silly of me not to suggest if you had checked for fuel? <THROWS TOMATOES>
The "run" tube is about 1.5 inches high or higher in most bikes, "reserve" opening at the bottom. An odd thing happens when riding off-road, your fuel jostles around so much that it will still keep feeding to the carb when it is well below the "run" level as long as you are on rough ground. As soon as you hit smooth ground, the bike shuts down for lack of fuel.
This effect also really reduces the capacity of "reserve". On my street legal KTM I have about 25 miles on reserve while street riding. Off road that is reduced to 2-5 miles and maybe 10 by leaning the bike over to get the gas in the other side. I don't know if the Blaster tank holds surplus fuel on the right side, I HAVE NEVER RUN IT THAT LOW! <good natured teasing>
