5 of 5 Really woke up my 1600 March 28, 2021
Reviewer: Michael G from PA  
Used this kit to replace the stock carb on my 1600 powered 70 camper. Was really impressed with the increase in performance . No its not a rocket but hills i used to crawl up i now can keep a steady speed. And i have increased my acceleration and highway speed.  Like all CB products the quality of the kit is excellent. Everything went together fine. My Bus fires right up and idle is nice. With ict carbs The main jet takes a little more work to swap as its inside the carb bowl But its not bad and worth getting then right.  Still get very good mileage also. I would recommend this kit over a stock single carb any day.
