Someone please help me out here. I am getting ready for a desert ride this weekend so in my infinite wisdom I thought it would be time for a tune-up on the BRP.(03 XR650R). I pull the carb and take it to a carb shop and had it cleaned.. it was dirty. OK I get it back re-assemble everything and NOW THE BIKE WILL NOT START.. What is more frustrating is that it will run for about 2 seconds then dies. I HAVE TRIED EVERYTHING.. NEW PLUG, CHECK THE FUEL,.... Now when I got the carb back he did unscrew the pilot..so I screwed it back in and took it to 1 3/4 turn out. Bike currently has 175 main and 65S.. I do not know what else to do.. If anyone has any ideas.. PLEASE LET ME KNOW... I NEED HELP ASAP.. Also where should the the throttle stop be.. he had that all messed up as well?
