CARBURETOR INFORMATION:
Models: Yamaha Blaster
Engine Modifications Recommended:
Work best with professionally ported cylinders.
If used with stock cylinder porting, compression should be raised 10-20%.
Example: To raise compression without porting DRI can rechamber the stock head to raise compression

Power: Keihin 34mmPJ Carb delivers very good rideable horsepower. It will make the best power between 1/4 and 3/4 throttle. Gain can be up to 10%

Optional Upgrade Modifications :
DRI SUPER FLOW mod: a machining modification performed in house by DRI. Improved performance on all Keihin carburetors at all air speeds. Improved air flow efficiency.
Works well in all applications

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 restrictive and stock box does not let in enough air. For DRI recommendations see below

Keihin 34mm PJ 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) call for additional information.

Notes :
Keihin 34mm PJ Carb works best with PTR Banshee Pipe & Fat Boy Silencer. It will do very well with either the Midrange or High Rev Version
