Starting chatter When i try to start my bike i get only alot of chattering. the engine doesn't try and turn over. lights work fine. Used to be that i could hold the clutch in and that would stop the klaking. could it be a starter problem?

You are in the car and truck section, please re-post.

The chatter is due to low voltage. Check all the connections. The battery may have corrosion that lowers the voltage.

No relay "chatters" normally, I would replace the relay first, they are inexpensive and that will eliminate that as the problem, plus those are alot cheaper than an ECM, I wouldn't suspect the ECM as causeing a relay to chatter! I say relay is the problem.
Good Luck !

Yes, you are missing something. The days of removing the battery cable ended with Generators. An Alternator will self destruct if you do that. Be certain to remove it and get it bench tested. Usually kills diodes and often regulator.

the doors clicking sounds like a problem in the door lock circuit, often in the door jamb. If you inspect and find broken wires in the door jamb, do not repair there, you need to replace the entire length. All repairs fail quickly. The wired need to be new and flexible.

On the no start with new battery, be sure to test the neutral safety switch.

Any chance the valve spring has collapsed? Cam shaft thrust washers missing? Cam shaft bearing gone bad?
Please rate this solution. Thanks!

would replace starter and inspect battery, cables/terminals also if problem still chattering u may have damaged the fly wheel the chattering is the starter not fully engaging the fly wheel. most likely starter but bad battery cables would also cause same symptoms hope this helps u

Check the ring gear on the clutch basket to make sure the teeth are all in good condition. Check the starter clutch and armature assembly and make sure that the teeth inside aren't chewed up.
