Saw this in JP Cycles. I have a 2003 NT Carbuerated. I was wondering if this could be used to check fuel/air ratios and idle speeds? Has anyone used this item and if so, how well does it work? I am looking for something to use on carbuerated bikes to make sure I am getting the most HP and to be sure my fuel/air mixture is right. Trying to avoid giving money to Harley dealer and dyno. Any other suggestions on diagnostic tools for carb bikes, let me know

 

I just put a screamin eagle on my 06 carb standard and it loves it. its not really a diag tool, but it changes the mixtures afull throttle and retards the timing by 5 degree
