The best way to upgrade a stock carb!! It is the best kit I have ever used!!! Jet kits are a little cheaper but this takes out all the guess work. No more lean back firing or running rich from over jetting, and the engine warms up really fast.

I love the better throttle response. But you don't get the benefits of this until you install a high flow air filter. Gas mileage slightly improved.
