My V-Specs have by far been the easiest engines I have ever owned to tune.

If it wont start it needs a plug. If it stalls either it ran out of fuel or the clutch bearings have gone bad. These things are incredible when it comes to ease of tuning.

Bought a new Speed ran one tank at home and took it to the track. On the first tank I flipped on the back stretch waited a while no marshall coming walked off the stand across the track picked it up carried it back to the pits threw it back down and went back up on the stand and kept going without flaming out on the 2nd tank. I couldnt believe it. I love these things best engines ever.
