[vxshane]

now have two vx one 92 and other 94 both 49 state models one gets only 38 mpg hi and 92 only gets 41,also has anyone turned a hatchback si into a vx wonder if anyone tryed and said will never do that again also noticed anyone buying a new bike for mpg get the new honda enduo 230 L model a mag .reported it gets 93 mpg so scap the tiny mopheads get a real machine,i f anyone has the f model for dirt let me know the mpg you have got and if this model easy to turn into a street machine,any help from a true vx expert would be helpful i havent had these cars long but even poor shape thought i could get 45 boy was i wrong,has anyone got the rated 56 mpg with cheating like drafting or coasting to a stop,even going only 65 mph i only got 41 with my 92 but it does have an aftermarket 02 on it
