Welcome to the pocket bike planet forum! I personally don't know anything about the r23, but I'm sure someone else while chime in...Hey there guys, new guy on here. Just looking to introduce myself. I have an r23 4 speed manual 110cc super pocket bike. Looking to mainly keep it stock until engine gives and then I’ll do a swap for something slightly bigger. I’m the mean time, I have found out both of my tires have small holes in them and need replacing. Any place I can find tires for these at a reasonable price? I also lost the small pin that goes in the clutch lever cover. Any idea where I can find one of those?
