XTZ660 Electrical Parts ? Misfire.

[Ralph]

Hi all. I'm in the same situation as Chimpy12 who posted a misfire question about 3 weeks ago.

Like him my bike will start, idle and run well for about 30 minutes then if you shut off the throttle it will give a quick misfire and try to cut out. If you do let it stall it won't start again unless you leave the bike to cool for 5 minutes, then it starts on the button.

I know it sounds like a coil problem but I've put a brand new one on and it didn't help.

Resistance ways everything meters out ok to the book specifications. I've redone all the wiring in the ignition circuit with new wire and connector plugs. Also simplified it somewhat by leaving out the sidestand switches etc.

So I'm begining to think it might be the plug cap or the pick up coil by the rotor. It could be the CDI unit but I thought it would be more likely just to either work or not rather than behave in this manner.

I'd like to ask if anyone has experienced certain trouble with these components and if they produced similar sort of symptoms before I go and spend a whole lot of money on the wrong bits.

Someone is pointing me towards the stator coil and other people have mentioned the rectifier/regulator but I think these parts have nothing to do with the ignition, the're only part of the charging system.

All help appreciated
Ralph
