We sell between 5 and 10 a week mate and have done for years, and nobody complains about spark gap. We regularly run GT30s at 0.75mm gap mate. (Although no real benefits on a YB after o.7mm)

If you want bigger than that then you need to go to coil on plug as opposed to wasted spark.

P.S: I dont HATE you at all. In fact, i dont hate anyone in this world. Life's too short. If your software is old, i will upgrade it FOC as i did with all the older boards.
