Couple questions.... I did the blue wire mod and I am currently working on the bk mod.... After I get this squirt down under a second , any suggestions for jetting..?? Theres a 162 main in now.... I know motoman 393 has this listed but for some reason I am unable to open the jetting spec chart..( I suck at computers!!) also what is the knob and line coming from the exhaust side of the carb..? Its hanging down with a small bracket on it unfastened to anything?? i just got this bike yesterday with no manual and its my first of the newer thumpers..Ordered a manual today , Wont get it till next week.. Thanx in advance for our replies..
