I have installed a 8" monster works adjustable riser on an 09 XTX, along with arctic cat M series bars. The rx1 cable I installed has just enough freeplay to give slack at the lever. But, the tors system engages at part throttle. The dealer says that the stock cable cannot be used with a simple extension. Is there any truth to this? What cable can be used, as I am sure many put 8" risers or higher on?
