As some may know I’ve had quite a few electrical issues since rebuilding the bike , after replacing the wiring loom , fuse box , etc
I was still having starting issues ,sometimes the bike would start sometimes not when it won’t start it’s as if the battery is dead, but it’s fully charged
I’ve traced the non starting down to the 2 wires behind the generator cover , if I take the cover off it will always start with plenty of oohph in the battery , put the cover back on and it’s as though the battery is dead
Now on to the bizarre starting....if the side stand is up ,flat battery...put the stand down and lean bike on it , full energised battery and it will turn over and start
Does anyone have any idea what is going on here ?

What battery are you running? Is it a decent one or an el cheapo? Brand spanking new , 2 days ago about £40 off ebay The issue seems to be when the bike is upright off the side stand and the side stand is up it wont even turn over , if i put the bike on the side stand it turns over freely and fast and starts more or less intantly |

I asked about the battery as I also had one off eBay for about that kind of money. Charge was good on the bench but failing massively under load. Brand new battery was faulty.

I'm pretty sure you'll have tried this already but I'd check the red and white wire from the rectifier for any problems.
another quick test is to disconnect the cable from the starter solenoid to the starter motor and push it against the live terminal on the battery with the bike stood upright, it might tell where theres a problem or it would let you rule out a faulty solenoid. hope this is of some help

I'm guessing something is'nt connected properly when the weight shifts sideways on the bike it connects when you stand it up it disconnects,are the fuses ok ? I've had them in the past look perfectly fine but have a fault inside the cap where you can't see it causing intermittent problems you could try jiggling all your connectors too . well that's my scientific analysis anyway

Just had starting issues with my 125 Super Dream so you have my sympathy. I have never owned a 250 Dream but I assume it is similar in build to the 125. I have had it in the past where a connector in the headlight had corroded almost all the way through and gave symptoms of a dead battery due to high resistance to current flow. One thing I would try is wait till it is dark and with an assistant, see if you can spot any sparking when you put it on the stand. This problem sounds to me like you have a broken wire somewhere, that is making intermittent contact. Have you tried a spanner directly across the starter solenoid terminals to see if it turns over? The side stand being up could be trapping a wire and shorting the battery to ground and so it will go flat.
Do you have a wiring diagram? If not, you should be able to find one on the internet. Good luck.
Thomas.

Are you getting the lights on the dash (oil/neutral) but nothing happens when you press the starter button?

Yes ,oil and neutral lights light up But they are on wether the stand is up or down If im sat on the bike with the stand up it wont turn over , If im sat on the bike with the stand down it wont turn over but as soon as i put the full weight of the bike on the side stand it turns over nicely and the bike will start |

Check this bolt/connection.  |

It's the battery, behaving when tilted.

If as suggested, the battery is misbehaving, it seems to me that, if you have another car, or bike, connect the car or bike battery to your bike with jumper cables. If the bike starts, then its a battery issue.

IMHO nothing to do with battery this is poor connection/broken wire.
I would remove the side covers then sit on the bike, ignition on starter button pressed presume nothing happening because not lent over on side stand. Keep the starter pressed and then in turn move the bars from lock to lock, gently move the wiring around at the sides of the bike particularly where the starter solenoid and battery connections are on the right, rock the bike gently from side to side, just try and find out in more detail what makes the starter motor cut in.
However my guess is a poor connection on the main battery leads circuit to the starter motor via the starter solenoid and including the main earth to the engine/frame, think you had the engine turning over only slowly at one point even though the battery fully charged. My best guess is earth connection/s, a lot of strange automotive electrical problems are down to poor earths and you have been having some strange faults  .
Anyway don't see what the problem is for Saturday, just put it on the sidestand...

I’m going to leave it now for the ride on Saturday as I don’t want to start messing around with it and make things worse I am now thinking that the problem is an earthing issue that’s been made by having the frame powder coated ,so my first port of call is to take all the engine bolts back out and scrape the powder coat off |
