Head gasket?

Yamaha TDM 850... | Answered on Mar 02, 2015


It sounds like you just need to flush your engine and clear out the sight gage.Get some good motor flush and a can of Marvel Mystery Oil. Go ahead and pour in the motor flush and Marvel.Run the bike at idle and about 2500 rpm back and forth for about 5 mins or so constant.Then drain it all out and replace with clean oil and filter.That should clear out whatever gunk you have in the engine.

Before replacing it, check the tensioner...it may be broken. Also check the guides. Make sure the cam sprockets aren't loose or cracked.

Hi there,

Well, the oil filler cap is located on the left side of the your bike, check at the downside of your bike (upside to the back breaks). you can easyly open it up by hands.

Good Luck!!

Thanks

Hi, Austin before testing any electrical component in the Starting Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries. The following is a list of usual suspects that will cause your bike not to turn over.
1. Ignition Switch is in the "OFF" position.
2. Ignition Switch is faulty.
3. Engine Run Switch in the "OFF" position.
4. Engine Run Switch is "FAULTY" or corroded.
5. Check the 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.
6. Bank angle sensor needs a reset or is faulty.
7. FOB battery low or dead.
8. Faulty ignition switch.
9. Faulty starter button.
10. Faulty kickstand, clutch, neutral safety switch.
11. Security alarm needs a reset.
12. Starter relay, solenoid, starter motor or circuit wiring faulty.
13. Starter armature or field coils have failed.
14. Main fuse or circuit breaker may be blown or faulty.
15. Faulty ignition relay.
16. The electric starter is working but starter clutch has failed.
17. Check for engine trouble codes.
