yeah it works very well, I have been doing it for years. The torque hit of the bottom is sensational

What kind of step you talking??
On dasa motors iTunes 130 low 125 high. Stock 46's

I would normally run about a 135 low and a 120 high or even a 140 and 115
Of course it depends on the engine

That can be fine for a flip but Im thinking thats a little hot for WOT runs. Unless there is a restriction upstream the venturi.

The total fuel delivered is the same.

Alrighty boys!!!! So I did what I said and reverse jetting my poop and no joke, gave me the extra bottom end hit to be able to flatwater flip my glass 61x Phantom! I can't believe the difference it truly made. Runs amazing and plugs are perfect chocolate brown. If anyone else is thinking about doing this for the extra bottom there looking for I would do it!

what jetting and popoff did you end up with? I have a very similar setup except dual 44 blackjacks instead of OEMs.
thanks

From what I understand,all blackjacks come reverse jetted.

my 650 6M6 with protec pipe uses reverse jetting
my 61x does not
I assume it is because the 6M6/Mik44/Protec pipe combo

do you remember your jetting specs? i have a ported protec 6m6 with protec pipe and would like to try reverse jetting to fix my issue. single sbn44
