to be honest it really doesnt matter unless that machine is going to be pushed to its end constantly...and yes I am sure about the blaster because we have a couple in the family. The blaster is oil injected and the warrior is a 4 stroke, but a warrior has alot of power that may be a bit too much for her, depending on her abilities and her brains ( no offense ).
The blaster has an oil resevouir under the seat that needs to hold the 2 stroke oil, which is injected into the motor when it is running. You can modify that to run mixed oil, but that is the only way you would mix it.
Of all the rides out there and beings she is 13, I would run a smaller ride for now and then if she really wants to move up then trade or sell and then but...but the blaster is sooooo light that reverse isnt needed...
a warrior has reverse, but I believe it may be to overpowerful for her. Remember I do not know her riding ability and can only base it on a normal 13 year old girl. Reverse is an overrated ammenity for most cases. I would get the blaster and tell her that reverse is there...it just consists of her 2 feet and a few muscles
by the way I have 2 daughters of my own, and they love riding...but they also know when I buy them their first toys, they get what they get and if they want something else they have to pay for it themself!
Good luck mom!!!!
