i just aquired 2 yerf dog 90cc 4 wheelers and one needs a lil work and the other one runs pretty good. one stupid question is how can i get rid of the tank below the fuel tank? i have never had lil cheap quads like this before and want to shed some weight and do not really know what this tank does......i know this is a freakin retarded question, but i had to ask it....thanks. another question is since these quads are not high performance atv's what other mods or tech info is out there for these heavy machines....? is there a material out there that would be decent enough to make my own intake filters....? thanks for all the help.....

 

The only stupid question, is the one that you didn't ask about before you broke something and cost you money.
To sum up my reply:: modification is the norm for most. I'm doubtfull there are alot of aftermarket goodies but surely there is a filter.
