They help with the 600, 700, & 800 twins but I haven't heard of any benefits for the smaller twins. I would save the thirty bucks and mayber gear down one tooth on the top sprocket or look into clutching.

Boost Bottles are for people that don't know to jet your sled on mid range and bottom end.  Wast of money   IMO   Riley
