Price: $850, including $437 in upgraded performance parts.

Payment can be made via PayPal. I can ship to any location in the USA via US Priority Mail Box for a reasonable additional fee. This kit is sold “As Is” and there is no guarantee as to how it will work or perform on your specific bike and setup. The carbs were working great when I removed them from my bike to install new Mikuni racing carbs from Bonneville Performance.
