I was just able to make 8" chumps with stock America risers work safely with only having to buy a plus 6" extended clutch cable and rerouting the brake hose to the right side (only works with Speedmasters) and moving the throttle cables to the right side of the frame spine. Good luck with 10 inchers, if you need longer controls, be safe and buy what you need. I should mention the wires to the headlight just reached far enough with the 8" Chumps. Let us know how it works out.
