Does anyone know if they make an air filter adapter so i can run a kn air filter? has anyone built an exhaust for one also?

its 6.5 hp. dont get your hopes up. its doing all it can do. for the money, even if its not much to spend, your talking precentages. even 25% gain, which you will never get, is only a little over 1.5 hp. you wont feel that.

Thanks for the reply. i figured it couldnt hurt but what do i know?

i said the hell with it and i am getting an exhaust! ya i know im a fool but at least i'll be told what the hell were you thinking

gained 2mph which took the top speed to 13.1 by myself and 8.2 with 2 people and a fat dog

I am running a 6.5 intek on a go-kart. I was told there was a aftermarket carburetor I can put on this to bring this thing to life. I am trying to educate myself on this engine to get as much speed as possible.

Look into affortablegokarts.com and Oldminibikes. com. You can build a reliable 6.5 that should put out around 13-16 hp depending on budget. There are tons of carbs and motor mod options.
