Hi. Just finished the Howell V Twin & thinking about building the V4. For the V Twin, I converted everything into metric via CAD but it was very tedious. Are there V4 metrics plans available, don't see on website. Happy to pay for same.

Hi.
Just joined the forum. See below pic of Howell V Twin I am working on. Its running but somewhat erratic, further tuning needed:(. One of my other engines
