giuseppe_evangelista Posted December 26, 2016 Share Posted December 26, 2016 Hi everybody and Merry Christmas, I have this problem, when I turn the engine on it goes with one cylinder for about four minutes +/-. Within this time sometimes it work both cylinders for some seconds and then again it happens till it is heated and works perfectly. I have changed sparks, cables, spark pipes and so on. Still cant' figure out which is exactly the problem. I really need some advices Link to comment Share on other sites More sharing options...

giuseppe_evangelista Posted December 28, 2016 Author Share Posted December 28, 2016 Now, what I can see is that I am trying to start the engine, doesnt' go and I feel smell on unburned gasoline... That means there's fuel but not spark I suppose... Link to comment Share on other sites More sharing options...
Moderator Cynic Posted December 28, 2016 Moderator Share Posted December 28, 2016 Still could be carb problem on bad cylinder (if it has carbs, what year is the bike). Have you swapped the spark plugs good side to bad side? The engine will need more fuel when it is cold and a stronger spark. If cold start or plugs are old the not working engine will have fuel but not enough so you will smell fuel. Link to comment Share on other sites More sharing options...
finnerz89 Posted December 28, 2016 Share Posted December 28, 2016 Being a 900 it's fuel injected. Try the link below for info, these bikes are known to have issues with the cold start system http://www.jbx9.16mb.com/ Sent from my E6553 using Tapatalk 1 Link to comment Share on other sites More sharing options...
giuseppe_evangelista Posted December 31, 2016 Author Share Posted December 31, 2016 Thanks finnerz89 I'll give a check to the link. As for the sparks they are totally new as well as the rest of the cablage and pipes. What I have to see I think is if a strong spark comes out of the cable because I'm afraid that couyld be the magnet... Cylinders have a good compression and seem to work properly.. Thank you though for the advices! My TDM is a 900 2007 year of production 65.000 km Link to comment Share on other sites More sharing options...
