hows everyone doing? im aaron, just recently bought a grubee skyhawk gt5. last weeked put it on a schwinn ranger. iv still got some loose ends that need tending but it ridable. vi got plans to swap out the front forks if i can for the forks on my mongoose xr-200 so i can have front discs. hate the way the normal rim brakes feel. i also wnat to mod this engine. i know its a cheap engine so the first thigns id like to do is make it more reliable. i was thinking the jaguar cdi, exhaust and better carb. how do i know what carb i have? i know mine does NOT have an adjustable needle and had the idle mix screw caped for epa.
