Three questions:
1. How do I check head clearance? I think I saw a video on how to do but I can't remember where I saw it.
2. I heard that JP is offering an O.S. line of engines, it this true and when are they coming out?
3. You here having had JP engines, would you recommend getting one, I run mainly club races and have been told that a mod motor is too much engine here. But the top racers that show up from time to time all have mod motors.
thanks
