Guys,
I understand that the consensus is that oem CV carbs on the XS work best with UNI filters.
But is there any difference if non-CV carbs are fitted? I have a pair of linked 34 mm Mikuni flatslides on my XS, and are currently using tapered oval K&N filters. The bike runs great, starts easily and idles smooooooth. I have a set of UNI filters I haven't tried yet, that require a short adapter tube, maybe 40 mm or so. The carbs have a 55 mm OD, and the filters are 63 mm ID.
I am also planning to remove the stock battery box next winter, since I am using a much smaller battery. This will allow me to try some velocity stacks between carbs and filters, maybe as long as 4 to 5". I hope this may improve the torque curve somewhat, utilizing the "third harmonic" of the intake duct. I guess around 10" from inlet valve to end of stack can be a decent starting point. But that is for winter...
