hello im getting ready to hopefully start my jdx4 project that has dual 34 mkuni setup .it has basicly an 800 motor with pipe and cdi ignition it is .020 over any idea where to start out on jetting would stock 76 lf440 jetting be close ?? would the pipe make it run rich/lean /different ?? also what about the 22 vs 23 differences any thoughts ?? thanks wade

If it is '75 800 engine, then yes, use the jetting for the '76 Liquifire as a starting point. If the engine is a later '77 or '78, use the jetting for that year Liquifire. The 23LC has more horsepower, partly due to higher engine RPM's and controlled cooling
