ITs been a while sience ive been on here cuz ive been busy riding... On the last ride of the season it was a beautiful day perfect for riding. everything was lookin up i was rippin through the trails on our property like no body business when all of a sudden... The bike would die out whenever i would hit the throttle... even a hair... I was like what so I turned around immediatly. that wasnt soon enough aparently, It died like 10 seconds after that. It wouldnt start and because I ahve a 426 I wasnt about to flood it tryin to kick it over in the middle of the woods. So I walked it back about a mile or so through sand mostly downhill... I get back break out the tools. The first thing I did was pulled the fuel bowl drain plug... It was brimmed with rich black dirt.. not sand. Heres the kicker I have a 6 or 8 ( I dont remember ) micron fuel filter in the line after the petcock. and my air filter was dirty but not that bad and it was on right. How on earth did the dirt get in there? Is it possible to have dirt come up trough your breather tube on the carb? Im puzzled. Any help or insight would be nice so this doesnt happen again. Thanks guys.
