NSR 125 wont even bump start

[Prottecttor]

Hello,

I during last 2 days i have replaced spark plug, new battery, literally ALL new fluids and an air filter. Before this the bike wont start from starter but it did perfectly fine with bump start. Today it wont do any. I Will mention that the wiring is done very poorly, Lot of isolation etc (prev owner). I have no idea whatsoever about wires So i do not even know where to check. When trying to bump start it sounds like the engine started but after giving it trotthle it chokes and dies.
Any suggestion where to start checking?

First check for a spark. Also look to see if the plug is getting wet, to show fuel is getting through. Check compression. If you can't check compression properly, how much pressure does it put on your thumb if you put it over the spark plug hole and try to start it?

If it won't run, either fuel, compression or spark isn't up to scratch.

There is a spark, checked today. Bike has to have compression because i rode it fine for last 2 weeks. Holded power and everything seemed fine.

I have checked, plenty of pressure on the thumb. Spark plug is getting wet, there is a spark yet the bike still does not start i Will mention that the wire from servo is not really connected to anything.

Ok i borrowed a kit and tested compression. It is around 127psi. I looked over the starter motor and as assumed it is worn out. This should not matter because i cant even bump start the bike. I shall start checking the wiring but i have 0 idea about it. What wires could prevent engine from starting?

120psi is the bare minimum. You really want over 140psi.

127 should still start though. If you have spark and compression, albeit a little low, I'd be looking at fuel next. If it was a wiring fault, you shouldn't get a spark.

I'd consider getting the starter motor sorted before anything else. Trying to diagnose problems while bumping it ain't no fun!

Get a wiring diagram, and a multi meter suitable for 12volt stuff. The meter need not be an expensive one, say £15 or less to do the sort of stuff you need to do on this and other bikes. If you dont have a multi meter ask santa for one early!

Once you have the wiring diagram, just interest your self with the wires to do with the ign circuits.

Find out what the timing marks are on the flywheel, and check ( check dont assume ) that the piston is at TDC when the flywheel says it should be ( sheared flywheel woodruff key possibly, rule that in/out first ) at TDC.

Its a question of ruling stuff out one by one for you, others, with the bike in front of them, could drop on the fault in 10 seconds flat, or it could take you days/weeks/months.

get a WIRING DIAGRAM and be methodical.

As a matter of interest, do any lights like the neutral light "flash" when steering turned lock to lock?
