I'm looking to relocate the bars on my soon-to-be-acquired 2003 CRF450 approx. 10mm forward and 10mm up w/a BRP top triple clamp and bar clamps. Is this safe with the stock throttle cable, or do I need to order a longer throttle cable from terrycable? Also, does the CRF have a return cable, or jst the throttle cable??? Thx.
