Need more top speed new to this

[Ethereal_Corpse]

I just got a greyhound 6.5 engine from harbor freight. It moves my go kart pretty good.

I have no idea what type of muffler to get to give it more top speed. Any help would be great thanks.

Your engines governor restricts max rpm to 3600. So unless the governor was removed, just installing a header alone wouldn't gain any higher top speeds.

Check out this link: http://www.affordablegokarts.com/
You'll find performance mod info on the right side, and headers/speed parts for sale on the left.

govener removal

if you can get inside the case on the output shaft side of the motor. Lay engine flywheel side down. dont touch or pull on on the crank shaft or cam parts. look to the back lower left of the case and you will see a small plastic gear, just remove the teeth or the whole thing. all your looking to do is stop the conection of the gears teeth. be sure to clean out all plastic debris. after that put motor back together and thats it. affordable kart also has great directions and pics to do this aswell. this has been a crude rundown.
