So I'm riding my bike with a 44T sprocket RTcarb sbpXchamber down main street at around 30MPH and loving the breeze when I herd this loud popping from my exhaust then all the sudden my bike took off like MAD!!! I pulled over to see what happened and my Xxhamber came out of the head, And I look behind and theres a cop walking towards me grinning and he says DUDE YOU HIT 37MPH. Now thats awesome.
