i had just gotten back from an hour of riding and my step-brother comes out with his new pipe on his yz125 begging for me to come out again with him so he can try it out. so i go along and down the trail the thing starts loading up on me but when i hit the gas it bogged. i come to a stop and it wont start. i let it sit for 2 minutes, kick it and it runs fine for about 5 minutes then begins to do the same thing. so i decide im gonna head home. it runs fine for another 300 feet then finally loads up, bogs and dies and i had to be towed home by a quad via an old hose. what gives? it's almost doing the same thing it did when my carb was clogged. good gas. sketchy pre-mix (halvoline tw-3) but seems okay. what are the causes for loading up and bogging like that? it was just sitting there and idling like BWA BWA BWA BWA BWA. then when id hit the gas GURGLE BLEHHHH dead.
