always hard to start (she breathes fire and demands miles as a sacrifice)solved

[carrier]

Solved... in the end it was the battery. Turns it the last time I took off the tank I forgot to turn the fuel tap back on. The moral is check the battery first!

Long time lurker first time poster.
A little while ago jackasses tried to hotwire my bike without removing the chain so after failing they knocked it over. A guy fixed it for me but since then its always been hard to start. A whole lot of running the starter, throttle, turn off the bike, turn back on, repeat until after three or four goes it will come to life, sometimes with white smoke other times with a backfire. So what's going on? Just went for a ride turned it off and couldn't get it to start a second after turning it off.

Other threads talk about a breather hose but 02s don't have them.

I took a look at the spark plugs and they look fine though they seemed a little oily or was it fuely?

Thanks for the help

Edit so I bought a 1994 ducati monster and decided to see what would happen if I just boosted it... started right away. So that means its the battery that knsckered or the alternator isn't doing its job because it doesn't run indefinitely after a while the revs die. So going to get another battery and see if that solves it!

Edit 2: its not battery... maybe it was part of the problem but not the full problem... so what am I missing

So far I have

Changed the battery
Changed the spark plugs
Changed the Cdi
Changed the starter cut off relay
Checked the fuel tap
Check the hit coils
Checked the pick up coils
Checked the alternator {visibly fine but the resistance is a little high 0.6 ohm for every wire.)
Am I missing anything?

The bike now sparks "weakly" and if I hold the starter it rumbles but still cant get it to idle... is it not getting the compression needed? I went back to my original cdi.

When it's spinning over and you're using a bit of throttle does it try to start or is it not firing at all?

Sounds to me like the ignition barrel is damaged.  If they've cocked about with it, it might be that not all the contacts connect so you get power to most stuff but no sparks.  I had similar when the connections inside were dirty, it might be worth starting with contact cleaner down the barrel and turn the key on/off a few times.

[carrier]

Hmmm, I did start imagining that turning the lights off when starting helped. I shall get some right away and give it a try. Thanks

Edit, just to add it doesn't try to start it just turns over

[limax2]

Just adding to what Lawrence has said. The white smoke is normal when it's cold and a bit damp outside. The backfire when it starts suggests unburned fuel in the exhaust caused by the engine spinning over with no sparks.

As I wait for my contact cleaner and wire brush I've noticed that my battery is at 12 volts and when I try to start it it goes to 9-10 volts...think I need a new battery?

As soon as you said it starts better with the lights off i immediately thought iffy battery!
I'd charge it off the bike first if possible, then measure the voltage before starting then after starting and make sure the bike is charging it okay.

[His Dudeness]

New battery time I reckon. Sounds like one of the cells is dead/dying and the voltage is collapsing when you hit the starter. Give her a push start and as darsi says check if the bike is charging the battery when you rev it.

[carrier]

Isn't it not sparking because the amperage/voltage is too low? How would a push start help? Just because the starter motor wouldn't have to turn?

Is it better to measure if its charging using ohms?

It will bump start with a flat battery, and quite easily too with these bikes.
I'd guess a good battery with no load should read at least around the 12.8 volts mark, and when charging with engine running will go above 14 volts.
Cold weather, age and sitting idle without a regular charge can all affect battery life span.

[Fazerider]

That sort of voltage drop while thumbing the starter is to be expected. I don't think that, or the fact that you are having to run the starter for a long time before the engine fires, indicates a duff battery. Quite the opposite in fact.
I'd be more suspicious of the mixture. Are you applying choke before trying to start? My Fazer starts readily without choke in warm weather... in cold conditions it needs it, but it has to be applied first. Weirdly, if it doesn't fire up without and then I apply choke, it just floods.
So, if you've not been doing that, give it a try. If you have been, make sure your choke cable is working i.e. pulling the little bar at the top of the carbs that actuates the four choke plungers.

Hmmm, I'll try bump starting it but I doubt it will work


I've only tried the choke after it hasn't worked, I'll try starting it with the choke on right away. If I try starting it and then put the choke on it doesn't help, I have to take the choke off, keeping trying then it will start.

Would that make my mixture too rich? If it is that should I be turning it down using the idle screw?

From your story, I would think that maybe you will find that you may have more problems than just your battery and too much focus is put on there by Darrsi and His Dudness. But plonk a new one in anyway, as you need one if it's not charging properly to spec. But she is spinning enough by the sounds of it to start.

Also, your story indicates that the bike was starting grand (even with a dodgy battery) prior to when she was tipped over. You indicate that you got somebody to fix your bike straigthaway, so if the bike was mechanically sound after being fixed by that guy after the tip over, then the battery and bike should have started away like as it was prior to the tip over IMO.

Even though you might have a dodgy battery,  I also would be looking at things that could have been dislodged after the bike slammed onto its side which now maybe has hindered your fuel supply. I would look at your Fuel Filter to see if any of the crud that was in it got knocked about and settled in a way that is obstructing the flow inside the filter to some degree.

Also it just maybe possible that if there was sedemant in the bottom of the tank or in the carbs bowls, that could have been knocked about and worked its way onto your pilot jets and blocked them. I'd drain the float bowls to see what the state of affairs is there and if the fuel is clean or dirty.

Also another area to consider is this guy who did the work and what he actually did. You said a guy fixed it for you. Who is this guy??....was he a qualified mechanic???....has he worked on Fazers before???.....you never said what he actually fixed that was broken??....could he have tampered with somethng by accident???....could what he fixed....isn't fixed at all or have made thngs worse??? Did it go down on the TPS side (exhaust) and that the TPS got moved or damaged?? There is so much lack of info here that you need to come back to us with.

I shall start from the beggining


Some douche tried to hot wire my bike by cutting all the wires coming out of the ignition and then wrapping them all together, which quickly fried a few fuses, he/she also yanked a wire out of the connector while doing that. Then it was tipped over.


I got a mobile mechanic to solder everything together. So just lifted the tank, reconnected the connector and soldered everything. I had replaced the fuses prior. Since that point on the bike was abit harder to start. I thought it might have been a bad solder job but I hot wired it properly and still it would not start.


Also if I push it really hard and leave it over redline too long it shuts off, still have power but engine won't turn, the starter will turn it but won't start.


It fell on the exhaust side. As time has gone on it has gotten worse... harder to start.. or it might just be this colder weather. Drove it from Bristol to London no problems... before I knew about the redline issue.


I was also worried it was a fuel issue so that what I'm going to take a look at next.


Thank you all kindly for helping, hopefully will get to the bottom of it.

He's touching 9 volts and you don't think there's a battery issue at all ???  :lol

Well I can see were both Fazerider and yourself are coming from.

You maybe right in saying that there is a battery problem with only 9 volts....but that might not be 100% given until further tests. He had severed wires, blown fuses and a lot of screwing about done to those electrics. What if in some way that all this skullduggery has in turn damaged the rectifier/regulator?? That would change the game then. The battery could be perfect still, but just not receiving a charge and just dipping down to 9 volts trying to run the fuel pump, dash lights, fuel gauge, digital clocks, TPS, ect ect when he took his reading when the bike was running.

What myself and Fazerider are saying too, is that if the battery is goosed, then he obviously had 9 volts before the incident to begin with, and it was enough to crank the engine and keep the bike going with lights all along. He had no starting incidents prior to the attempted theft.

And even after the incident, he also said that the battery is spinning the motor mad, which suggests that there is still plenty of jizz in the battery to at least crank the engine. That leads to believe that he has other issues than just a battery....if it is a battery at all.

[darrsi]

It does sound a bit messy admittedly 

[AdieR]

I'm not convinced it's a failed battery; battery voltage will dip when starting (starting uses a hell of a lot of juice). If it were a reg/rec fault, I'd expect to cut out during a run due to no charge.

Are all your fluid levels right?
You say the tank was lifted - you haven't got a trapped / kinked pipe where it was put back down?
There was mention of dirty spark plugs - have you replaced them?

Is your tip-over switch functional and it's wiring ok?

My FZ has been on it's side twice (knocked over by a van, and 6 months later a car), and mine never had any starting issues either time.

It may be that you've had a fault-in-waiting, and the tip-over has pushed it over the edge (no pun intended).

[carrier]

Your a cheery lot aren't you, its all doom and gloom. :lol

The starter engine doesn't take that much power however the sparkplugs take a massive amount and if it isn't 100% they won't work, so I'm betting battery, but I also think there's another culprit, but I think its a fuel problem. I don't think its running lean, but maybe there is crap in the filter and when there's a nice steady draw from the engine it let's in enough but if there's too much of dies or not enough a vacuum occurs. Those are my two guesses...

The 02 models doesnt have breather pipes to kink.

Quickly tried just choke and start and nothing. If in try a bump start should I choke it while bumping?

No
