Guys - I'm Building a new 06 race motor since mine lost compression. Going with JE 75mm high compression pistons, carrillo rods, JSB cams and springs, milling off head and cylinders, port/head and valve job. RWHP goal 190-200. Concerned OEM radiator wont handle the extra heat.
My question to those who's built motors, have you had cooling issues when racing with a built motor using oem radiator? What have you done to lower operating temps?
I'm Planning on just gutting thermastat and put washer in to slow water flow for now. Should I do more now??!!
Now that everything is off the bike, nows' the time to start making those changes.
MY stock motor (158 rwhp) raced at temps of 180-190 (no fan) with oem hose routings here in southern California
Thanks in advance for your input.
