alls i ride is 110s and my g/f has a 04 crf70, its all stock and she loves how it starts first kick and she can ride it all day without a problem, but they are SOOOOOO SLOW! what are some ideas to make this thing go good without doing a bore kit, and it has to be reliable? thanks to anyone who can help me!

TB 88 KIT!!!!!! without race head though! Split the gaskets, a mild port job, and it will be her favorite bike for sure.
