Hi, Anonymous I would love to help you with your engine or chassis noise but I just loaned my brand new pair of listening ears to your local dealer's chief technician so he could take your bike for a test ride and give you his professional opinion and estimate about your noise and repair cost. If you are a little short on "DRACHMA" and a Dealership is not on your list of fun places to visit then perhaps the list below will help soothe your worried mind so you can make an informed decision.
3. Brake Rotors---BUZZ
7. Fronk Forks---Plunk
9. Head Gasket---HISS
10. Hydraulic Lifters---TAP
12. Rear Shocks---SQUEAK
13. Shifting Trans---CLUNK
14. Solid Lifters---TICK
16. Connecting Rods Go---KNOCK-KNOCK---who's there, it's me "*****"

Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Fuel line to carburetor or throttle body pinched or kinked.
8. Carburetor float stuck.
9. Fuel injectors clogged.
10. Severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
11. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
12. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and CDI box.
Spark plug cables in bad condition and shorting check for leakage in the dark, cable connections loose, or connected to the wrong cylinders.
13. Ignition timing incorrect due to a faulty MAP, CKP, O2, TPS, sensors.
14. Faulty neutral, clutch lever, or kickstand safety switch.
15. Faulty fuel pump or fuse or relay.
16. Faulty CDI box.
17. A stuck bent or burnt valve.

You likely need a new plug if it has been wet from fuel but then you need to find out why it is wet. If it is wet it could be fuel or oil related so you need to find out which. If it is fuel related it must be running very rich so it should also be blackened like with soot and if oil wet it should be oil black on the plug.
You might try using a ruler between the bolt holes to see if they are the same distance apart on both parts. If you don't want to do that, call a wrecking yard and ask them to look up interchangeable parts. They can do that for cars, why not bikes?
If you are using key with red bow to start, then dont use that.Use the key with black bow.-----Disconnect the battery and wait for 10 minutes, then reconnect the battery and try to start the Yamaha xmax with any other key.The immobilizer light is flashing, that's the indication of wrong key.This light is flashing because its not detecting the key which you inserted in the ignition to start the bike.--------- In you have any other key, then try with that key, but first disconnect the battery for 10 minutes then reconnect and try with other spare key.This will help.------------
Exactly, why this light blinks?--------------
This light blinks if someone tries to steal your bike and uses a different key or method of starting your bike..it wont start unless your key that has a programmed chip is inserted..just a safety/security feature.--------- Or if your bike key chip is got faulty.In the key there is a chip and in the ignition lock cylinder there is a sensor.If that sensor do not detect the key, then this immobilizer light will blink.----------Try cleaning the chip in your key.By spraying wd-40 and then cleaning it with a dry cloth.Also spray wd-40 in your bikes ignition lock cylinder. Spray the wd-40 in the key hole.Let it remain there for few minutes, then insert the ket in the key hole and wiggle it to on and off.Then try to start and see.---------If the bike starts with another key, then the previous key which you used is faulty and the immobilizer chip in the key has to be replaced and then programmed by the dealer.---------But if the bike not starting with another key too.Then the problem is with ignition lock cylinder sensor.That sensor in the ignition key lock is faulty and not detecting key.The ignition key lock cylinder with sensor has to be replaced, by the dealer.-----------In some cases this problem gets resolved automatically after exact 24 hours.If you dont insert the key in ignition key hole.----------This will help.Thanks.Helpmech.
