Question about 2006 Yamaha Ybr 125
Posted by Anonymous on
Hi, Anonymous and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. 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.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.
10. Enricher valve inoperative.
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.

hello there guys, listen a top tip is when the engine's cold tip the bike almost right on its side nearly touching the floof, wait for the petrol to poor out of the carb over flow pipe, this should take a matter of a few seconds, stand the bike back up again and kick and that baby should start right up, if it does then you have a problem with your float, if it still doesn,t then take it to a shop and get them to check it out, hope this helps. regards sam

Firstly check that you have a spark at the plug gap and if so is the plug wet with fuel ?If so on both counts try rubbing a pencil lead on the plugs gap ,this may sound daft but the lead from the pencil increases your sparks power five times .But only use this idea when bike fails to fire .if problem carries on check your air cleaner unit ,and if dirty change it .

will it turn over,if yes add fuel sta-bil you can get this at any auto part store.The gas you buy now days only has a shelf life of 3 weeks,so make sure you add to fuel if your bike will be sitting for more than that.
