Cons:

1. Complex Installation: Installing the 86931 carburetor kit can be a complex and time-consuming process, requiring specialized tools and knowledge.

2. Cost: The kit can be more expensive than stock replacement parts, which may make it an unattractive option for some budget-conscious riders.
