Every P/F record on the books has been set using one of our carburetors. Our carburetors are under constant development. If you want to run with the "BIG BOYS" this is a must. Now, we machine them in house out of billet aluminum.
60' Launch Can mounted on the front cylinder. This is a must for those short times and preventing lean conditions at the hit of the throttle, which damages pistons.
Our "D" to "D" manifold spacer increased the manifold volume that helps prevent cylinder robbing for greater mph.
Billet Velocity Stack
We manufacture an adapter that accepts the 1" Guzzler fuel valve and splits 1" I.D. hose into two 1/2" I.D. (or #8AN) lines to feed the carb.
HRP Billet Aluminum Nitro Carb. After 25 years of modifying the S&S carburetors, HRP now CNC machines a billet fuel carburetor in house. Every P/F record on the books is set using one of our HRP carbs.
Our billet bowl holds twice the capacity of the stock bowl and has a large threaded cap at the bottom for easy jet changes without removing the bowl.
Our new billet throttle assembles have a built in adjustable wide open throttle switch which can be used to activate most timer systems. We designed the assembly to activate the WOT switch when the rider comes off idle instead of full open for faster response times.
New One Piece Main Jets. We CNC these one piece main jets for the "D" Fuel Carburetors in sizes up to .330".
