Well I had this on a 15 predator surface drive and I went from 20 mph to 15 after adding this performance kit was easy to install and really helped to open up the motor. Will be buying more parts from gopowersports soon.

Tested on a Duromax 440cc 18hp I dropped in my kids Baja Dune (ex 150) several months ago. Noticeable difference from the stock 440 and crisper response. The jet that came with the 420 kit is still much larger than the stock on our 440. Very little filing on adapter to clear the head of the flange nut that retains the carb. Easy install. Would definitely recommend

direct bolt on is nice!
choke lever retainer needs to be finessed to fit properly. but not to bad.

It's one of those 'Must Haves'

These upgrades have me wondering why I waited so long. My package included the header pipe and with the increased air intake and the 420 jet, my Preditor 420cc has really come to life. It has never run this good, even when new.

Great kit for the Predator 301. Our sons, 12 and 16, got it working within an hour. The design is very well thought out.

Couldn't wait to get this out of the box and try it on the track! Easy to install and it fit perfectly without any modifications. My kart now has a lot more power and it brought my 40 series torque converter alive. As always, product was shipped quickly and intact along with status updates along the way. Go power sports delivers everyone, thanks and keep up great work.

Switched from a centrifical clutch to this torque converter clutch. What a phenomenal difference off the line. Seriously, the difference in acceleration from a centrifical clutch was like adding a turbo (interesting concept to consider) to the kart.
