Misfire,in one of the cylinders

Lean mixture, cant run on idle, low rpm cut off... Check your intake air leaks with brake cleaner spray.

Sounds like a sprak plug noise?

Did you ever figure out what the problem was?

[@apriliaracingchannel4290]

Nope. Engine was inspected, so I think it's a harness issue.
