Hi Everyone
Been keeping an eye on this thread hoping you could sort the problem out. About a month ago my bike started the playing up same as yours & has now given up the chase.
Starts fine no problem after 5 mins when engine hot she stops, wait five mins starts up runs 1/2 mile & stops.
Checked petrol,filters & all connections no difference.
This morning I had it picked up & taken to Triumph dealer.
Mechanic who picked up my bike thinks it is the CDI unit (Ignitor) as everything else looks ok.
Anyway I will let you know what the problem is dealer will be phoned twice a day until fixed. Or else I will have to bring ADEY with me as back up.
