maybe selling my blaster

ya you will be happy with something bigger. unless you have tons of money to upgrade the blaster then selling it and getting a bigger quad/bike is a good idea if ur bord with the blaster. plus with a bigger quad its easier to get high hp out of them while a blaster pretty much maxes out with regular mods at 35-40hp most bigger quads have that stock.
 
I think you should get a honda trx 250r or a suzuki lt250r they are great machines. If you get a lt250r get an 88 or newer cause they are 6 speed with a powervalve.
