I recently bought a 636 and the man i bought it from said he snapped off the push rod and id have to get a new one. I got a new one and re assembled it but the clutch is too heavy and wont engage. snapped the new part again. The bike is stuck in first gear and apart from not being able to shift, pulling in the clutch does nothing. I am already ordering the part that snapped but i dont know if the entire clutch basket needs replaced or if its a problem inside the transmission itself. Id appreciate any ideas anyone has for helping me diagnose this.
