I would guess depending on how much your clutch responds
the limiting factor is going to be wheelie issues .
Again depending on the chassis setup,
I would try 16 / 42 ( gen - 1 )
and see how that does for 60' and wheelie issues .
Plan on trying some other gears .
One tooth makes a difference .
I have all the gears 42 - 48 ( gen - 2 )
and depending on the setup
end up running 44, 45 and 46 .
We'll see this year
if I can get away with
a 47 on motor or not .
