This is the place for anything & everything relating to the legendary Honda CR500 CR480 & CR500AF... Some helpful links: http://www.CR500riders.com http://www.bannedCR500riders.com http://www.servicehonda.com Now for my post... The Keihin 39mm PWK carb has long been the upgrade-of-choice for the Honda CR500R. My question is, has anyone here installed the new ESR (Eddie Sanders Racing) 40.5mm carb? http://www.eddie-sanders-racing.com/oscmax/product_info.php?cPath=57_58_17&products_id=27 IMHO this is THE BEST CR500 carbie!!! Any experts, please share your jetting settings... Main/pilot/needle/altitude/temp?
