I am running my clocked JL right now at Sun Lakes. 9+ minutes run time. Mugen P5 plug JP-2 and Byrons Pro 2 30% with a 7 mm venturi. Still have my tune a little rich cause the track is super loomy with dozens of ruts so I need to keep the tires at contact as much as possible. God I love this engine. thanks Neal!! You have a winner and I sold one for you to team member Shane Mann. Ship it out bud. I'll send the $$ on Monday. It's turning heads and I'm blowing away ninjas and Novas running rich
