Deep Busch, I asked above but never heard.......what happened to your motor to nessitate a full rebuild?
Technically, one could use one shaft to do both. They instruct not too and I agree, it does shift smoother using 2 shafts. According to weddle, these hv24 and 25,'s were designed around the baja 500 racers. Most generally the 250 too 300 hp class. When I first heard that. I thought hmmmm why rest on such low power units if your going to rate it at 600 hp input. Sean said that Baja runs wot the vast majority of the 500 miles. Sand rails make short bursts but no real sustained pulls like the desert floor of Baja 500. They split the shift shafts to end missed shifts in the race class's. Thatscwhat I was told, I'm going to choose to belive it until it pisses me off then I won't
Mid engine is a tiny tiny part of the market as they are difficult to build.
The fun part will be designing and building a rev lock out. It right and up. I can see hitting rev speed shifting 3rd. !!
