Bought a crf50 about 4 days ago. With in the first hour of ride time pop a tube... TLDR. Whats the best way to keep this from happening. local Honda shop is full of retards. Im running stock with kenda milvilles. 2.75. I've replaced three tubes after some just general riding. My buddy with year older bike and what seems to be a wider tire has had zero problems. HOW do I remedy this? I ran about 22 pounds in my tubes and didn't do anything crazy whilst on the bike. Other local bike shop says I'ved "rolled my bead" on my tire and I need a new one. Will a new wider tire fix this? What have you guys done? My pitbike project really isn't taking off that well. Any help would be greatly appreciated. Thanks.
