What brand drive belt do you guys recommend. I have a 2014 viking with little over 3k on the clock and it seems you have to give it a little bit more throttle than what I think is normal. This is my first machine with this type of belt drive. My harley was belt driven but different..Also thinking about a JBS kit for xmas.the only thing is buying 2nd hand machine you don't know what has already been installed other than cosmetic things. Thanks in advanceClap
