USA and Canada :
 

     As of May 2010,   YuanDong SkyHawk  2 cycle engines have been EPA certified to the new rating of 40-CFR-1051.  The new 2010 & 2011 requirements now have both the US importer on record and the China engine manufacture both involved in obtaining EPA certification.   This new requirement is also part of Canadian environmental law.

    In other words the EPA certification process has changed and now involves the US importer on record who must now be responsible for the engine manufacture’s emission quality standards.  In the past EPA had no way to legally enforce their rulings at off shore factory locations so in this way they have control by making the USA Importer on Record be totally responsible.   This can be a good change but without a trusted contracted fiduciary agent in China this process would be unthinkable and beyond control.

    China GAS and Don Grube play an important role in this process as fiduciary agents and licensed exporter.  EPA Certification for bicycle engines can no longer be obtained in China by the factory alone as was done in years past.   This new process of having the engine and importer both approved is lengthy and very costly running approx. $30,000 for 190 hour lab testing and EPA fees for 2 years certification 2010 & 2011.   

    Nationwide Access  > dba: www.GasBike.net has successfully obtained EPA emission certification to enable importation of SkyHawk Gt2B48cc and GT5 66cc 2 cycle bicycle engines and legally sell them for off road MoPed application for the years 2010 and 2011 in all US states except California.  

    All 2010 & 2011 engines use a different carburetor and muffler than used in years past.   New requirements entail a longer palladium insert in the catalytic muffler along with an air shield, a special CNS-YD carburetor and a special fuel line.   4 cost increases!                              

    YES; cost increased substantially with the $30,000 EPA expense all amortized in and now the USD / RMB exchange rate is at an all time low of 6.35 as of Oct. 2011.   

 
 
 

Choke is external cable controlled.   Dual air / fuel mixture screws are factory set.  Late production will have a RED air cleaner like on the std. 2009 SPEED carb. to enhance clearance to seat post.                        

Any of the standard air cleaners will fit this model.   ( EPA models will have the air adjust screw factory sealed. )

#3 YD CNS EPA Carb. for USA

 

      Heads up; When using the New CNS carb. you must use a shortened intake tube or carb. will hit the set post. Short and Long tubes look alike unless you have them side by side. If clearance is a problem we suggest using an Off Set Z tube option.
 

All 2012 Engines have the new one piece flywheel Crankshaft assy.
