I bought this 1997 Deauville last spring, rode it to work all summer and it was OK, I dared not touch the choke, it never needed it at all. Towards the end of summer it would flood more and more easily on starting, so much so that I got stranded a few times. Economy was never good. 59k km.
I did the valves, changed the plugs, changed the airfilter, changed the main jets, cleaned the carbs.
Now, if I manage to start it, it runs OK, bit rough, a bit up and down on the idle, sometimes it stops and will not start. It backfires. It revs well once the flooded plugs have dried out and I manage to start it again.
It floods really easy on starting and I dare not touch the choke again. If I miss the opportunity to blip the throttle on start then I have to take all the plugs out again and dry them, and you know what fun that is....
On my bike the choke lever is DOWN for OFF, is that right? I have to push this all the way down for any success.
When I checked the carbs I made sure the choke cable has effect, and it does. All looks mechanically good.
I managed to start it without the air filter and it ran at a steady 1000rpm.
Can someone help, this is driving me mad. The mix screws are factory set aren't they?
I replaced the Iridium plugs and it started first time, still a bit wandery on the idle.
