The problem is with performance. As far as I know there is no headder available for the Sachs cylinders. That means you don't have the option of using a tuned pipe or cannister system, leaving the DA/ZDZ/MVVS quite a bit more powerfull than Taurus/Brison.
Hi Wings,
Actually, headers are available from KS, just like about every other engine made....if that is an issue....but what you really should be looking at is what people typically use, and I think(pure speculation) you're still looking at 90% of people are using pitts-style mufflers with these engines. Although I have not seen numbers for a Taurus with a canister or tuned pipe, the numbers with a pitts-style exhaust, are at least as powerful as a DA or any other 50cc motor out there, and maybe even better at swinging bigger props, such as a 23X8. One number I recently got direct from Taurus, because they ran a comparison for me to my MVVS 45 running a 24X8, was 6250 RPM using a 24X8(I think it was an NX) on a brand new engine with their pitts-style muffler.
