yeah i put a big front sprocket on there cause i set it up to ride wide open. less gear.and different pipes will help with the bottom. the carbs are 30 mm. and probably need to be dialed in a lil better.i am used to clutching it up to get moving. that don t bother me.you will either take the advice and get fatties or toomeys. or improvise adapt and overcome no bottom.you will get the feel for where the pipe comes on and learn to ride it.
