Pe,I think the MVVS 116 should be compared to a 120 not a 100.You pick the smallest 100cc engine which is actually 97cc and compares it to a 116 and I'll bet the ZDZ didn't have a full tunes pipe setup on it like the MVVS 116.If you want to compare Pe why don't you put it in the category that it belongs.Then compare tuned pipe setup to tuned pipe setup.
