Performance upgrades for B&S 18hp Vanguard?

[sdowling]

I have a 1989 Max IV with a B&S 18hp Vanguard. I am looking for easy ways to gain some HP. I heard about putting the 23HP cam in my engine. I am looking for other ways to get some additional power.

Performance V-Twins is a good place to check out. There's lots of potential for big power out of an already powerful Briggs 18HP Vanguard.
