I have a 1991 xj600 that wont start she turns over ok and she has a spark at the plugs also fuel is getting to the carbs as well she ran at the weekend but now wont start been working on her since monday if anyone has any thoughts on this please could you help me many thanks

Sorry man... no help on the technical front, but you should post an intro in the new member section.

ok no problem will try many thanks

update on this problem have drained all the old fuel out of the tank and had the carbs off as well and given them a good clean out and still she wont start going to try new spark plugs next

If the new spark plugs don't do it then check the pickup coil,if it test ok then your cdi unit may have died.Your bike has 2 coils and the chance of both of them dieing at the same time is about 0.Ru getting any back fire or poping out the exhaust?

If the bike was running and then just up and wouldn't start again thats the type of thing cdi units do. It will still spark just at the wrong time you can check it with a timeing light

the bike does back fire just hope that it is not the cdi unit as they are not cheap
