Forums 🚥 PiT STOP 🔧 Hyosung Technical Help Identifying Jet needle for my 2005 comet 250 Reply To: Identifying Jet needle for my 2005 comet 250
On the needle , put it on the “lowest setting” (which is closest to the pointy tip) , that will lift the needle 1 more step out of the carb , then you have some fuel much sooner around 4-7k , its good stuff. {{No extra washers etc, don’t know why other places say this but never mind lol}}
As you have a K&N, maybe consider 95 and 97.5 main jets as maximum.
Though, you will ride the bike first with only the slide needle enriched, clean the spark plugs first. If its dark brown everywhere , the fueling mix should be fine. Last worry should be clearances on the valves, so that exhaust valves breath better once its up to temp (it gets hotter if the ex-cams have less gapping)
