New top end, new muffler so I won't get kicked off the track again (db limit), and a nice set of worn out tires I got from the track's tire dumpster. I turned the fastest recorded lap I've done on this kart, 49.2 seconds. If I can get the carb tuned for part throttle and loosen up the rear, 48's won't be a problem. ]]> Sat 04 May 2019 14:30:13 +0200 https://www.gnarpowpow.com/videos/17345/shifter-kart-75-mph-on-dumpster-tires-around-gopro-motorplex/ https://www.gnarpowpow.com/videos/17349/gopro-motorplex-shifter-kart-practice-old-tires/

I went from the rental karts to this shifter, this is a clean lap from my first day of driving it. ]]> Mon 07 Apr 2014 14:28:04 +0200 https://www.gnarpowpow.com/videos/17326/shifter-kart-gopro-motorplex-modded-yz125/
