So I finally got my x19 registered. Now onto the tuning part. Where should I start? new carb? new air filter? What other motors will fit into the slot of the 110cc? Any recommendations on where I should begin modding and any other good tuning tips? I got the air fuel just right on this carb but it still cuts out at WOT and I'm thinking the stock carb is the problem after reading a bit. This thing is just plain way to slow to have out on a main road the way it is. I need some ideas for how to get this puppy up and moving. Thanks for the help in advance!
