hmmm seems I lost a post here ..but most likely it was me ...yesterday I did some more work to the carb ...I improved on my idle circuit mod ..that makes this carb have 5 different adjustable circuits to adjust ….I had to bring even more air to the idle circuit when idling and and carb plates closed basically ...im totally amaze of much suction is going on through that tiny hole where the idle mix screw used to be … wow ….I moved the idle gas feed to a different spot and made a home made jet to cut the flow of gas going to where the mix screw was as it was way to big for the modded motor of the bike ,,, ifound a way to make even more air come to this mix screw spot to lean the mixture even more than I had it set up to before ..this seems to have worked hugely in the right direction ….today im going one step further and introduce this this extra air to the air filter area ...I call this the carb balancer ive done this before … what this dose is when the throttlle is applied its stops the air flow to the idle circuit as the main carb air flow over takes the pull of the idle pull and stops this air and then this should richen up the charge when under throttle ..witch It seems to need ,,, the carb air balancer is a neat thing to me and totally of my own hands and mind …. but like we all know here when motor is changed like I did by shaving the block ,,many things must be change to adjust to the difference ...so today il actually finish what I started yesterday since the improvement warrants it ….
