    I searched and searched for a decent velocity stack for my 49CC Honda Ruckus. Here in Florida, tuning the ruckus is all about the CVT and Intake dimensions/jetting. After coming across this site, I decided to give two of the stacks a try on my personal application as well as another and I had great success.

    I gained about 3mph top end (maxing out between 61 and 62mph) and the engine continued to pull throughout the rev range where it typically (despite all tuning of the stock internal engine and carb) would stall revving earlier. This stack is great quality and improved the AFR of my bike as well as the top speed. If you are using any other stack, sink drain, or intake on the market for your Ruckus/Metro, you are missing out.
