Hi have an 2002 klx250 with a 300 big bore kit, I am having troubles starting when cold, what spark plugs are people running In the same setup

 

Welcome to the forums!
A few questions first: what helps starting her cold? What works, what doesn't? How does she start warm? Has she been sitting a while?
And what carb and jets do you have on the bike currently? (if you know)
