I took my bike across town today to return the 1/2"copper pipe that was to big,i bought a 2ft 1/2"id blue air hose and hose clamp,the hose fits.
but it is still noisy,not sure if im going to use it or not.im not putting side panels on bike,my legs hide the engine anyway, i watched out for cops(in my town we have 1 cop car per street,city,statetroopers,sheriffs)if i see one i hit the off button and peddal,then turn it back on.but my peddal crankarms are falling off,i have a 3 piece set shoved in the 1 piece hole,but its not very tight.
