we have been running our stock mp-9's (we have 2)
with no air cleaner and without the stock baffle in the tip.
what else can we do to get a faster straightaway speed
it goes to 25 and youo can tell it is telling itself to stop
then after 26-28 it opens up without hesitation
after it hits 32 i can hold that speed on a straight as long as there is no inclines,as soon as yoou hit a hill its back to 25
but it still has good power so im not sure but we love to rip these machines through our town
thanks for any tips...
