I have been looking for mods for my Ventacci Pentora 250cc sports ATV, manual. I am going crazy trying to get the fitment correct, when on retail sites (ie. Amazon), I can not figure out with the selections given, which match my unit. I would like any info concerning how to make sure the parts will fit my unit

 

So the carb is labeled on the side(should be pz30 or smaller most likely) just have to make sure it’s the same configuration as far as the choke.
the shock absorbers are found by the length, like mine is 390mm for the back. If both the attachment ends are the same as your old one it will work. The cdi box’s are determined by the number of pins and if it’s ac or dc.
that’s what iv learnt so far hope it helps.
