A good, inexpensive upgrade for those pokey Vespa 50s. Works very well with a Performance Exhaust Pipe.Or a 16/16 carb!
***PLEASE NOTE***
Performance upgrades are considered racing parts and are not covered by warranty. There are too many variables involved with user-installed parts, and pushing the limits of your engine tends to wear parts faster. Use at your own risk!
Not legal for use in California on pollution controlled vehicles. Check local laws before installing.
