hello everyone new to the forum and to china bikes.
i just got a new xpro hawk 250 today. i put it all together and let it run and and cool a few times.
after that i ran the gas station and got some gas and when i got home the exhaust pipe right at the head was glowing red. i have not rejetted it yet
from what every one on you tube has said they run lean from the factory.
is this the problem? if so what size jet do you think i need? i am at 696 feet above sea level. i am keeping the stock carb for now but will mostlikly get a nibbi at some point.
