Cm870 jake issue

[ktmcandog]

Ive had a few in the shop for clacking when idling and spotted the suspect exhaust rocker flopping with the engine running cover off. The problem seems to be wear between the shaft and problem rocker as there,s a hole in the shaft that a spring loaded ball grabs on in the rocker arm to prevent movement when the rockers unloaded on the base circle of the cam. Replacing the shaft and rocker lever was the cure---ktmCandog!
