Michael Caddell –
My 2019 150sx came with the 36mm SC2. After my first ride, it was obvious that the carb was too lean because the previous owner was a woods rider and I only ride moto. I called smartcarb up, they pulled up the record of the previous owner and we figured out that I needed a richer metering rod and an updated float kit in order to suit my motocross needs. After these updates and following the unofficial smartcarb tuning guide, which is very easy because you can do the tuning without any tools needed, my bike rips. Starts first kick without even having to touch the gas, idles strong, and pulls very linear all the way through each gear. 5 stars for the customer service at SmartCarb and for an awesome product!

Got my SmartCarb running sweet!
Very impressive fueling with our temp not rising above 38 degrees yesterday. More responsive now, compared to a properly jetted Mikuni, and none of the ‘ding-‘ding off-throttle, just smooth response everywhere. I love how it rolls on before the power-valve and after. Not soft power before, stronger now, then good drive once on the pipe.
Feels better than a 125 should…
Can’t wait to see how it operates at 65 degrees, 85 degrees, and everything else next season.
Thanks guys!
Kevin
