Reed Cage & Intake Manifold Recommendations
Stock intake manifold should NOT be used.
Use DRI MasterFlow Intake manifold system (see in INTAKE COMPONENTS Section on this website)
Carburetors will perform BEST when used with PYRAMID REED VALVES

Air Box Requirements:
DRI strongly recommends NOT using the stock OEM Blaster airbox with larger carburetors (like 34mm & 35mm). Because the aitr boot is to restictive and stock box does not let in enough air. For DRI recommendations see below

Keihin 35mm PWK Carb works best when used with DRI 250R stock airbox (lid Removed), and K&N Air Filter. (slight modification to sub-frame and rear fender required) Price for box and adapter is $ 175.00 plus filter and outerwear. (call for additional information.

DRI also offers a clamp-on K&N filter if airbox upgrade is to expensive. Filter Price $42.50, Outerwear $15.95

Jet Kit Optional but recommended Jet Kit is built around settings DRI puts in Carburetors.
Kit is supplied with Richer and Leaner: Pilot Jets, Needles, Main Jets, in a polypro box.

Keihin 35mm PWK Carb works best with PTR Banshee Pipe & Fat Boy Silencer.It will do very well with either the Midrange or High Rev Version
