Hello,
I'm new to the forum. I purchased an Asia Wing RM250 dirt bike. At 1/3 to 1/2 throttle it bogs. I've tried the idle and air/fuel screw as much as possible but it has not helped. I know this engine is fairly popular and would like to get a replacement carb. Not really sure which model of Mikuni to get. I've seen others with the Apollo dirt bike use the Mikuni VM series but I'm not sure which size to get or the correct model number carb. Any input on this problem and carb would be very helpful. I tried searching the forum but could use some extra help. Thanks so much! I attached pics also for reference. Also, I live at Sea Level.
