Factory R&D carb add on

I saw some type of fuel accelerator by factory R&D that mounts to the bottom of the carb and supposedly gives a couple more hp. anyone heard of this or using it?

It is called a P38 lightning. Do a search on the boards for previous post.

Or you can do the GB mod, it has the same effect and is almost free.

what is the gb mod someone else was saying something about a bk mod haven't heard of either???

The BK and GB mod are the same thing, after Garrett Berg's death TT renamed the BK mod, originally named for Brian Kinney (Tim Ferry's mechanic) after Garrett since he brought it to the masses. Check it out here
