have 9 zenoah engines with black or orange boots on the same models. is one boot better then the other. does it signify anything? or does it not mean a thing?

The orange ones that I have on my zenoahs are made of silicon I think. The black could be rubber or something like that.

My newest G62, less than 2 yrs old, came with the black boot....if that helps at all. Give Ralph a call, he'll have the very direct answer you're looking for.
