What does it mean when it has the word JET in the title?

[recon chris]

Im trying to buy a 48cc 2 stroke from kings motors. The 119$ ones say they are the "Silver slant" kind. Other 48cc kits onely inches apart on that page cost 134$ for the same 48cc motor onely it says "Jet 48cc". So what does "Jet" mean and which one should i buy?

'jets' (as kings/gasbike calls them) are made by nantong jiali. i prefer them over anything else... my friend had one. mechanically much quieter than my HT (one of the $119 ones), and the casting and finish was all much nicer. pay more get the jet 66cc
