The yellow db30 that I did has a briggs 7.25 motor on it
with some briggs animal parts and a mikuni vm22-133 carb
and the stock disc has a hard time slowing it down
and I am going to take this new briggs motor a little further
than the last
I weigh 250 and it takes some power to make it happen for me
But it is crazy with a lighter rider
