Recently I bought a 99 Banshee (my first) its fast as shit but lately after it warms up it loses power it wont get out of its own way . Then I will shut it off start it back up and it will take right off for about 20 to 30 seconds then it loses power again. seems like the plug on the left keeps fouling. Pulled the carb off today did not see anything wrong. Any suggestions? The bike has Toomey T-5 pipes, Wiesco pistons, Boysee daul stage reeds, ported case, I rebuilt the carbs about a month ago but it ran fine up till now I did not change anything inside the carbs (Jets).
Thanks Chad
