Purchased a 1998 Gas gas txt 270 contact to follow my son on his beta. Im living in France and bought the bike off ebay, had it delivered, started first kick off the van. Went to use on the weekend, ran perfectly for 20 minutes then just cut out and will not start. Checked for spark , no spark. Checked kill switch, all connections and earths. Replaced, plug, ht cap, kill switch and ht coil. Still no spark, has anyone any good ideas, before i waste more money on a refurbed stator plate. I have now previous historty with the bike, it would appear to have had a fairly hard life , but was running fine for 20 minutes.
