I actually wanted to add the system to my SR5, I found a fellow T4R.org member who lifted his 4R and pulled the X-Reas system. He sent me his components but the problem was that the shop that pulled the system did know how to disassemble it. At all four corners instead of disconnecting the system at the check-valves they pull the flex lines at the shock which releases the pressurized oil.
The stealers (I contacted about a half dozen) all said that there is no way for them to re-pressurize any of the components and said to either buy new or send the system back to Yamaha and let them, if they can, recharge the system $$$.
One dealer went as far as to say it
