[smoking-cat-99]

I recently purchased my first sled a 99 Arctic Cat Z 370. I paid $1500 and really like it so far. Black Magic makes a kit for this sled it includes- 34mm twin carb, throttle cable, choke cable, airbox, intake flanges and instructions. I have read also that this will add about 10-15mph to it's overall speed. Is this kit worth it? Or should I stick to what I have? I really don't know it's top speed, we haven't had enough snow! Thanks
