flowed heads , fitted 1.940 inlets , these heads all ready had 1.900 and head work by another eng builder , flowed with mikuni manifold on head as what was on bike ,

after flowing with its manifold , I refitted 1.940 inlets to heads ,these heads had same seat bowl bowl id , still after fitting larger valves , low to mid lift picked up nice , cut new seat angles , flowed with s/s carby manifold on after rework heres figures , before and after flow sheet ,

this was were head manifold mods and changes , now reflowed with 42 mikini carby on bench , lost 30 cfm at top

reflowed with s/s G carby on same manifold head , this is what the flow bench monitored , the final carby used on this eng build but not flowed was a 48 mikuni , its on bike now , head valve mods , better flowing inlet manifold, larger carby , netted 10 rwhp , it may not seem a lot , but it is when eng was already making very good power for 95 cubic in ,
