Im working on a JR50 and it wasnt running when i got it. I have since cleaned the carb(removed all jets, etc and soaked in cleaner, blew out, etc) raplaced fuel lines and inline filter. With the bike in neatral the throttle range is nice and smooth from idle to full throttle. When i put it in gear its slow out of the hole and anything over 3/4 throttle it bogs. I cant seem to get the carb settings right. Im not super familiar with bikes. Can anyone tell me what the two screw settings on the side of the carb are for? is one high and one idle? right now the bike starts fine, if i put the choke on......the bike still runs. my mid range is ok. my low and high end arent right. Help? i removed the exhaust.....actually very clean. not much carbon build up at all on the jug end. im getting nice blow out from the other end. any ideas? i dont think its a dirty carb issue but how i have it set on the needles.
