there is no after market stuff in there i made a mistake. i thought where the adjuster is was the extension, but its not all oem. my issue was the top cable was rusted into the top of the adjuster making it not wanna come out. i finally pulled it out the furrel on the end of the cable stayed rusted inside of the adjuster nut, no biggie still was able to take a measurment. it was a speed bump just use to checking freeplay at the pump this 2000 sxr is the newest sled ive ever owned so alot of new stuff.
