Yamaha YBR 125 2006 not starting

[datahar]

Hi there I have as stated a Yamaha ybr 126 56 plate, which now does not start

Just before christmas it was becoming increasingly hard to start the bike, I took this down to the cold weather, tucked it up over winter and now want to get her out again now the suns out (I know I am soft)

I got my 600 diversion running again no problem, but when it came to the 125 it would not have it.

I ran the battery down trying to get it started, and now after charging the battery there is no life in the battery, this may be due to the battery as the levels were low which I topped up, but the lights come on and when I hit the starter button everything dims but no movement in the starter.

I got it to kick start before I ran the battery down, and I did get it going briefly both start and kick, I had to clean the plug before each successful kick (have replaced sparkplug tonight)
But now I cannot even get it going with kick.

This has happened before and I had to push it quite away back to my work then when I got back it started again
also it popped 2 brake light bulbs when it was running, just the brake not the side, do not know if that is important just thought I would mention it

I know how to use a spanner just not necessarily on a motorbike am abit annoyed this happened 2 months after its first MOT which cost me £400

any suggestions/ insight would be greatly appreciated
Thanks

Jimmy

I'd start with the easy stuff. Change the sparkplug and HT lead and I'd probably put a new battery on. Then go from there.

as katier said, do spark plugs ht leads, get a trickle charger onto the battery to bring it back to life, or get a new one.
check oil level, whilst bike is up right, not on side stand.
check air filter not blocked,
check killswitch,
check fuel tap is turned on and that the fuel hasnt gone off, maybe drain it out, and put fresh in.
as for bulbs blowing, check fuses, and the wiring, check no water has got into bulb holder.
good luck

If the battery has been left on the bike over winter, not charged and is dry, it's probably well fucked. Get a new one, they're not expensive. I just put a new Varta battery on my CBR, cost less than £30. eBay ftw.

If it's popping bulbs it might be a sign of a faulty regulator/rectifier which would also cause the battery to get buggered if the charging system is trying to dump too much juice down it. Saying that, a buggered battery can also cause the same problem as the electrical system can behave weirdly with it sitting on the circuit. Try changing the battery first before anything else. You did use distilled water and NOT tap water, didn't you? You can also get a hydrometer and measure the specific gravity of each cell if you really want to make sure the battery is bad. Checking the water level will often give you a clue as to how well the battery has been looked after (low level means it hasn't been looked at in ages and then the battery is most likely the culprit). Even if it's really low, the battery won't have lost any acid, just water, so topping up is worth it. If it's the original battery it's going to be 4 years old now - most likely at the end of it's life.

Replace the battery with a maintenance free sealed type for convenience, as it's annoying having to top it up.
