hello everyone i had a question. i did a search but wasnt able to find a solid answer. I just got a 6month old two brothers dual along with a juice box off ebay for $565, sounded like a good deal so i jumped on it ( let me know your opinion ). I was wondering if i needed to put the juice box on right away. i was looking to run it without the juice box for a bit but it seems that some people have issues without them and some dont. also when i do install the juice box is easy to uninstall when i need to take it to the dealer. i just had my spyder to the dealer a month ago and all the most current updates were applied ( so they said ), but will be going back from some of my 6,000 mile maint. Thanks for the help!
