I'm not sure what you mean by "engage the clutch". When some people say this, it means the clutch won't disengage the engine from the transmission. Others say it and it means that the clutch will not engage the engine and
transmission and make the bike move. It's the same way with the term "backfire". To some that's a pop from the exhaust, to others is a spit back out fo the carburetor.
Now, if you
took the handlebars off, you should have only has to move the cable adjuster in the middle of the cable. If you did not change any adjustment at the primary, you should only have to the adjuster in the middle of the cable to worry about. Make sure that the cable housing is seated in the adjusters like it should be. It they are out of the adjusters, it would may your clutch stay in the "pulled in " position and the clutch will not engage the engine and transmission.
Now, when you pull the clutch lever in,you should feel the resistance of the clutch. If not, the there is the possibility that the cable came disconnected in the primary case. This is rare but I have seen it happen before. To fix it,
remove the outside derby cover and you should be able to reconnect the cable with the clutch release mechanism in the primary. If you need a drawing of this area, contact me directly at
