this is a new model intake i have made for the upright sitting postition bikes such as the cafe, tracker, and traditional bobber bikes. it is tucked in tight to the chassis so the carb is centered as close as possible without haveing to do any frame mods. this model has shown great results and simplifies the use of one carb. the vm mikuni 36mm has shown the best results for all ranges low, mid, and top end. no more rubber intake or carb mounting issues with the stock setup. i run this on my mule bike as a daily rider when not testing other intakes setups.
