Hawk 250 brand new all mods trouble starting now

[Mikeward617]

Long story short, I bought a hawk 250 and it looks great, I am having trouble starting it. I did the ebay exhaust mod, pod air filter, mikuni carb upgrade.

Now, i have ridden the bike twice. It has trouble starting, it gets spark its the carb I believe.

I had a 120 main jet and it started on that and I think it was too rich, it has a 110 now. Still tough start and the spark plug was black on the tip. Gas also leaks out of the carb around the air filter. Not sure what to do from here I’m not a carb wizard like some.
