IanT Posted February 13, 2010 Share Posted February 13, 2010 I searched around and couldn't find anything that quite relates to my problem. I have an old YB100 that I got in boxes. I've put it all together and it started right up, idles fine. However, it the assembly I loosened the nut on the clutch actuator arm which turns the worm drive to press in on the spring plate of the clutch drum. when i loosened the nut the actuator arm snapped down and ever since I have not been able to set up the clutch so that when i pull the clutch lever at the handlebars, the bike goes into neutral. Sadly, while I am pretty familiar with two-stroke motors, I have never owned a geared bikes, just belt drive CVT transmission pedal mopeds from the 1970's. Can anyone hazard a guess as to what I might have broken, or is this just an issue of me not knowing the proper way to set up a clutch? I have pulled off the right case half, and I think in loosening the nut on the actuator, i may have pushed the ball bearing out of the wormdrive. the wormdrive is all sorted now (i think) but once i put it all back together, it still wasn't working. Final question, the case is currently drained of oil, do i need to have oil in there for the clutch to function properly? Thanks in advance.
