Engine doesn't start
« on: January 31, 2016, 11:27:19 AM »
My first problem with my bike... :(((

So my engine doesn't want to start. My battery is new, the starter engine is working, but the engine doesn't get started. Tomorrow I will take it to my service man.
He said it could be the starter engine, an electrical shortcut, or maybe a decompression valve (it holds the compression in the valve, and the starter engine can't kick up the piston, to run the engine). Do you know anything about this valve?

What do you think??

Your service man does not know what he is doing. He should have asked you was the sidestand up and the run stop switch in the run position. The Downtown does not have a compression release(decompression valve).

He is not a Kymco man, he repairing all kind of motors. It was a question from me, but I didn't know neither.
But that is a good news, one problem less :D
(I think I checked all the common problems, side stand, battery, runstop switch)

Thanks Karl!!

What year is the bike? How many miles? When was the last time the intake and exhaust valves were adjusted? What were they set to?

I too think it could be valves. Probably need adjusting.

If it were the valves, there would have been some signs like smoke or backfiring.
I've had the same problem with my GTI not starting. Puzzled me for hours. Come to find out that the new battery which I installed wasn't quite fully charged.
I put the battery on trickle charge overnight and success in the morning.

Having said all of this, check all of the general things. Check to see if all of your fuses are not blown, spark plug if firing. Also could be the coil.

Cheers

Okay everybody calm down :D It was the battery's fault...

I took the battery back to the shop, and they certify (after an examination with some kind of battery machine, I don't know the english name of it) that the battery is okay.
So I took the bike to my service, I told them the battery is good so there could be an other problem. My man make a jumpstart, then change the battery with an old one, in both case the engine started flawlessly. So it was the battery after all... :(

Now I am try to change back my battery, but they are not admiting my garantiee recleam, beacause "the battery is good".

This is Hungary, year 2016.. :D

Glad to hear it is working! However, I am really confused by how it could be the battery based on what you said.

Mr. Paul
No, in the service they changed the battery, so they checked the contacts...

Maybe one of the battery cell is shortcircuited?
There was not enought voltage to rotate the starter motor. Battery can't suck up the voltage from the charger.

If the battery does not have proper amperage the engine will crank but will not start. Had this problem many times with half charged batteries.
Glad you got it sorted.
