Hi all,
So I have a sound but well-loved Yamaha Diversion XJ900 from 1997. It started last year (for a few minutes) but hasn't been on the road for about 2 years.
I am trying to get it up and running again this week. When I jumped the bike with my car battery (as the bike battery is unfortunately dead) it turned over but no dice with the engine starting.
I have previously repaired the starter motor (by cleaning the brushes) so I don't think that's the problem. My best guess is the fuel has become varnish and will require a bit of cleaning. The fuel tap is open, the electric cut out switch is not on and the bike's in neutral so hopefully I'm not missing something very simple.
I've recorded the sound it makes - could someone who knows more about these things have a listen and tell me if I'm barking up the wrong tree?
Here's the link: https://www.youtube.com/watch?v=Bbi0EwA8VIU
Thanks!!!! ____________________ Current: Yamaha Diversion XJ900

Yes absolutely drain the fuel from the tank, open the carb drain screws and drain (if anything comes out ). Then try with some fresh, most likely will need cleaning out if it has been 2 years, but worth a go with fresh. You can hear the fuel pump is working too. ____________________ Previous : 09 Vanvan 125| 02' Sv650s || Current: 1999 Xj600n | 1992 DR650 RSE | 2005 Fazer 1000 |

So, I made a bit of a silly mistake - the fuel tap markings had become dirty, so what looked like "on" was in fact "off"....whoops!
Anyway, I turned the fuel tap back to on and tried again to start the engine. The engine still spins without starting so I gave it a little choke and some throttle...and....I smelt fuel. Strongly. So I stopped and noticed a bit of a puddle on the floor underneath the engine.
I didn't fancy causing a fire so have stopped for tonight to let it evaporate (the bike is outside so should be fine by tomorrow) and have put the fuel tap back to "off".
I guess the unused fuel while the engine is spinning has to go SOMEWHERE but I assume it's more likely there is a fuel leak somewhere - probably at the fuel tap or between that and the engine? Will investigate tomorrow....with caution!! ____________________ Current: Yamaha Diversion XJ900

So - the engine is running again, if roughly! Wahey. I replaced the spark plugs, made sure the fuel tap was unjammed, and opened the starter motor up again to make sure it was running freely.
The bike now starts with choke out most of the way and a lot of throttle, and it'll keep running with no throttle and 50% choke. Perhaps I didn't let it run for long enough to warm up, but when I closed the choke, it died instantly.
I still think the carbs need rebalancing or perhaps a full clean, and the valves need rechecking, and a clean tank of fuel and perhaps it'll be running smoothly again!
I still need to fix the calipers (they are jamming on the front brake), repair the leaky exhaust and fix the leaky fork seal and glue the handlebar grips back on (they are currently both loose) and probably some other things and then ... it'll be good for the MOT....possibly!! ____________________ Current: Yamaha Diversion XJ900

Old Thread Alert!
The last post was made 2 years, 301 days ago. Instead of replying here, would creating a new thread be more useful? |
