volume

Hello, My bike is throwing a P0001 Fuel Volume Regulator Open Circuit code and I cant seem to figure it out what the issue is. The bike idles rough, but when I am riding the its runs with no issues. Does anyone know what this issue is? Regards, jwolfson

It sure seems restricted for a 1300cc engine. Wondering if anyone has ever done any sort of dyno testing with somehow enlarging the intake air volume. Not even sure it would be possible without some serious custom work. Not saying 205hp isn't more than enough, just curious if there is anymore...
