Honda Cbr125r - Help needed!

[Jango]

Okay, so it's been a hectic week, let me explain;

Firstly, my ignition barrel randomly decides to wear down, leading to a ignition barrel replacement, took it too a garage, £82 bill.

Then, my indicators both die on my left side, found out to be a loose wire on the relay, fixed!

Getting ready to ride, go outside~ the wind either pushed my bike over, or some rat decided my bike wanted to sleep, anyhow, the bike could have been on its side for 3 hours at most, i pick it up.

The upper cowl is pretty much hanging off, headlight is waving around, but the bike starts! great right? well, after no more then 2 minutes riding it down to the parent house, my RPM sitting around 5k, randomly drops, i put more throttle into it, it raises for a second, then drops again, until it cuts out.

Okay, i start pushing it, got bored of pushing, try to start it... it starts, great!, no more then 10 seconds later, it cuts out, and hasn't started since.

I've replaced the spark plug, checked for kinks in the fuel lines, it has fuel in it, but the bike just isn't firing, i'm getting fumes belting out the exhaust, but it just won't start, i'v even tried bump starting in second gear to no avail, i can only suspect a flooded carb at this point, but it's been sitting for 3 days now, and still won't start, all the electrics work too.

So, i'm thinking either flooded carb, flooded engine, or what i learnt recently is a damaged BAR (bank angle relay), or tilt sensor?

I know the bank angle relay is located behind the headlights, which took the most damage in the fall.

Any advice is appreciated (i'm not a mechanic, or that smart with bikes, but at this point i have nothing to lose).

Thank-you.

Depending on the age (and the unexpected angle!) it could be something as simple as a load of shit in the tank has shifted about and clogged something up.

Quick check would be to try and start it then pull the plug(s) and see if they're damp with fuel. While it's/they're out check you actually have a spark and go from there...

If it fell on its right (offside) then maybe the kill switch was damaged? or a vital wire or connection came loose when the fairing detached.
Checking for a spark as easy-X suggests, is the first step.

1st Rule of Spanner Club: don't assume anything! The bike's had a physical shock, something that was hanging on by a thread before may have worked its way loose.

I take it that you've had a right good google?

This is pre-FI being an 06.

Open your filler cap and try running.

Is it actually sparking?

I don't think the older one has a bank sensor, I've thrown mine down the road and its stayed running for some time.

If you are whanging away on the starter be carefully you don't burn it out. The findings heat up fast due to the energy flowing through it. They are not meant to be hammered for much more than a minute then allow a few minutes to cool.
It harms the insulation which may not be a problem today but will give you shit later.

Check that there is fuel getting to the engine.
Turn over on the starter and have a whiff of the exhaust. It should stink of petrol. Even dripping out the pipe.
I don't think shit in the tank is too much of an issue but there is more likelihood of water being in there. From normal condensation events.
Being on its side then righted and started may have sooked a bit of water into the fuel line.
If you can drain the float chamber to ensure there is no water in there. Check if fuel runs out too.
It is doesn't then your on point to find the problem.

Coils for the ignition typically sit on the outside of the frame right above the engine and the lt wiring side is very vulnerable if the bike falls over as a result.

Are you sure it 'fell over in the wind'? The headlight and cowl hanging off as a result is a massive amount of damage just from that.

Sorry I missed it but did you say you'd pulled the plug and it was giving good spark?

Have you checked all 5he wiring and plugs behind the headlight/cowl?

It was working with the new ignition wasnt it?
