When the aerox is going down a hill it's fine, however coming to even one of the smallest inclines you would think it struggles, could the belt be slipping? has it just been stretched through use and needs a new one stuck on so that it will grip? Also - i know this is an age old question and i apologize. Rollers, what would anyone suggest for a yasuni Z on an aerox, where's the power on the Z, what rev's does the engine need to be running at to get the most out of the exhaust, it's just the standard ones that's in there at the moment, which I'm guessing are around 5.5/6g? Would around 3.5 - 4.5 be around the right weight to get the revs up to where they need to be?
its an age old quesiton nobody will answer... buy a few sets and experiment. what are the revs doing as it go's up a hill/stops performing as it should?
thought that might of been the answer, and tbh it just takes its time to get up to where all the power is, so I'm guessing it just needs lighter rollers gonna try getting about 4 grams or something see if they make a difference
