Hi Everyone - hoping someone out there will be able to help me!
My mate bought a divi 600 a few months back and everything has been working fine (we even took it on a trip to cornwall and back this summer - didnt skip a beat).
A week or so ago, he started to warm it up and after a couple of minutes it just died. Expecting it would just fire up again, he tried but no sign of life - needless to say he ran the battery down and found another way to work. He charged the battery back up the next day and tried it when it was slightly warmer - still no nothing, not even coughing and spluttering).
Few possible causes here obviously - here's what I've done...
Fuel coming out of the tank - check
Fuel coming out of the fuel pump - check
Plugs sparking - check (thought it might be a coil, but 3&4 are both working and run on different coils.
Also, the plugs seem wet with fuel after trying to start.
Now - its just the starter motor turning it over, its not even trying!
Im no mechanic (not by a long shot) but the only thing i can think it might be is the carbs, but would it just refuse to even try? Surely if its getting fuel and a spark, it should combust?
My mate is brassic and cant afford to just put it in the garage - would be super if i could get him out of a hole this one time!
Thanks in advance for any help given.
Stu

The bike uses a wasted spark system One coils does cyls 2 & 3. The other does 1 & 4.
If the starter is spinning but the engine is not, the starter gears are probably broken.
If its clicking and whirring its likely the battery voltage is low. Try a car battery and jump leads to be 100% sure the system voltage is ok.
DONT RUN THE DONOR CAR ENGINE. It can blow the bike's voltage regulator.
It could also be water in fuel or bad fuel.
Take out all plugs, turn off the fuel and drain the carbs. Check the drained fuel for water.
Drain some fuel from the tank to check for water. But if the fuel is a few months old drain the tank and use new fuel. Reconnect everything and try again.
Spin the engine with throttle wide open to clear fuel from the system.
If taking the tank off check all choke plungers are moving. They can stick open or shut yet the choke lever still moves.

Wow - thanks for the quick reply. We tried it off of a car battery - but same issue as when on the battery - wouldn't bump start either  Would water in the fuel really stop anything igniting? Fuel was only a few days old and was/is a full tank. Will try draining the carbs at the weekend - the guy at the local garage also said it may be a compression problem, but he just wanted him to put it in the garage. Thanks, |

This may or not help but. A number of years ago a friend of mine had a similar problem with his Norton, some ******** had urinated into the tank. In those days locking petrol caps were not fitted as standard. Initially he thought it was water in the fuel (and we have had plenty of water around over the last week) rainwater could find its way into the underground tanks via the vents etc. It was the Trading Standards who analysed the fuel and confirmed the findings. Guess someone was taking the **** literaly

Would I be guessing right that the bike has sat uncovered outside (frequently, maybe not always) in the rain?
If so I'd suspect water in the fuel. It can takes months for enough to creep in, or just a few weeks in heavy rain. It will sink to the bottom of the tank & be first into the carbs from the fuel tap & fresh fuel on top won't resolve it.
Drain the tank into a bowl, recover the fuel off the top & consider re-using it but leave the bottom couple of inches as waste.
Fill with fresh fuel & drain the carb bowls, let fresh fuel in, turning it over on the starter to get it through, see if it fires up. Nothing to lose but a bit of fuel & a bit of time.

Just done that, but had no luck so far. drained the tank and drained the carbs, put fresh fuel in and would not start. Drained the carbs a few more times, but still no joy. Now there is no water at all in the fuel coming out of the carb bowls. Going to let it sit for a while and see if we het any more joy. Will also look at the plugs again and make sure they are still sparking.

Success! Ended up dribbling a little fuel into each chamber and getting a few coughs, 15 seconds later it spluttered into life! Goto look at the filler cap now as this is obviously how the water got in in the first place. Does anyone know of any good fixes for this as the cap looks like its a rubbish fit and water is just allowed to sit there indefinately.

Excellent news  . There's quite a 'lip' to gather water, ain't there  ....... no tips for keeping the water out, but each fill-up you can soak it up with a kitchen towel (that's what I used to do anyway.) |

There is a drain hole in the outer ring under the filler cap, is it blocked ?

Of course! See, thats clear, logical yeller belly thinking.  Unblock the hole so that any water that has gathered there can fall into the tank. ;D |

Cheap nylon bike covers are only about £12.
