    bore old FCR or buy 07 new carb for crf450r

    by duneflyer » Fri Mar 16, 2007 8:21 pm

    hi guys. I want to get a bigger carb. I was just going to bore my stock 03 FCR to 43.5 and call it good. But, I heard that the 07 450r FCR carbs are reworked and are a better carb at 41mm then a bored out 43.5 one. Any thoughts?
