icorating5.png BEST BANG FOR BUCK!!!

Posted by Aaron, December 26, 2016

 I am very new to go karting, but luckily my kart had a stock 212 predator (with a performance header already installed).  Since this is just a for fun hobby my wife as imposed tight budget restrictions. So I knew if I wanted to make this thing fast  (obviously) I would have to be very careful with my purchases. I quickly decided the "212cc Predator Performance Air Filter, Adapter & Upgrade Jet" was the best way to start my project.

After a slight issue with the shipping (not Gopowersports fault, the shipper will remain nameless) that I've chalked up to the time of the year it is with the holiday season. In a true show of AMAZING customer service Go Powersports immediately resolved the situation before it really ever became one!

The kit comes exactly as advertised and as specified!! I chose the blue kit with yellow netting and it really changes the appearance of the engine.  But the great looks and ease of installation pale in comparison with the performance improvement!! To say it wakes up this engine would be an understatement! It improves power from idle to as far as you can Rev it! Throttle response and drive ability are also noticeably improved both in GPS data and the much more important seat of the pants-o-meter!

If I hadn't been fortunate enough to have already had the performance header I would have certainly gotten the header option. It is the combination of better air flow in (air filter and adaptor), more fuel (bigger carb jet & e-tube), more air out (performance header). Addressing all areas of engine performance at once gives you the largest improvement while laying the necessary foundations for all  future upgrades!

Next up:
Torque Convertor!
Billet flywheel (non hemi)!
Better valve springs!
Although new wheels and tires are probably going to be the next upgrade (safety)  I am currently running on mix-matched wheels and tires from garage donations 12-8 (or9)-6 and 11-6-6 because with the speeds this thing is doing it is very difficult to control!

Great job Go Powersports!!!  You've gained a customer for life!
