I'm having an issue with the rear shock on my 650 Turbo. It seems to have intermittent binding of motion and sometimes remains compressed. Today it remained so compressed that the side stand was unusable. Hours later it rebounded on its own. No oil leaks and it holds air pressure like always. Linkage is all good. The bike is pristine and only has 2700 miles on it. I am the original owner. I am wondering if this is not an uncommon problem and what can be done to fix it. Please help. I would like to keep it original and will probably attempt to disassemble to investigate but is there any aftermarket shock that anyone has had good results with? Does anyone have a very good serviceable OEM shock they would sell?
