William, that was what should have happened in the beginning, but the TaG class engines were never built to the same spec because they were all trying to start their own world-wide series like Rotax has done. They were never made to compete against each other on-track.
What we need is as new formula. Something that all the manufacturers will get behind. As Greg noted, I believe the CIK is working on a new formula. They’ve been testing direct drive engines with decompression valves for a bit now and something like that could potentially be quite lucrative.
Until something cool like that comes out and catches on at a national-level, I’ll be racing Yamaha with a few TaG races peppered in when I feel like it.
