Heard a noise all too familiar and came outside to find my dad ripping up the lawn on the Viper's first run. Watched it and when he hammers down from a stop it goes a good couple feet then bam the secondary clutch upshifts and it rips the BIG time. he said it felt like he fell of a 3 foot ledge tahts how hard it hit. Can't wait for my first run on her. Oh yeah I forgot to mention that he ran over my mom's brand new garden hose and poked a hole in it with a stud. One single hole of the 192 studs in his track .
