I'm 6'3" and wanted taller bars for a more comfortable ride. I purchased some Renthal high bend bars. It appears the stock throttle cable on a 2003 WR450 is too short to accomodate higher bars. Am I missing something in the adjustment of the bars or do I need to find a longer throttle cable? If I need a longer throttle cable, any tips on where to get one? Google has come up dry and I didn't see anything on the forums either. Thanks.
