Bryer Hansen –
The SC2 38mm was the finishing touches on my Beta 300 RX. I delayed installing it because I settled for how well the stock carb performed. Wow, was I even more impressed when the SC2 further improved the performance of my bike. For starters the fuel efficiency went way up! I am using about half the fuel that I used to. I ride all over Utah, Idaho, and Nevada, and with the elevation changes from 1,000ft to 12,000ft the smart carb is a no brainer. My bikes starts if you breathe on the start button and idles perfectly. You can crack the throttle with zero hesitation. The smoothness in corners is unreal. The consistency is phenomenal. I will continue to buy two strokes and install smart carbs on them!
