It was spinning at   thats why it it sounded like that.watch at 33 seconds as it gets sideways with me.When it gets warmer its harder to keep the front down on it.Pavement was dry but still cold . Also that was the stock carb on it.,It isnt lean at all i have it running rich on main jet.I had to go down a main before i done the video.It woundnt run out at 3/.4 throttle . Temp was different by50 degrees since the last time i ran it.So had to go down.I shot this video before the Scp pipe and It just showed to my front door.So their will be video to compare to after its done.
