i have a 1998 thundercat and for some reason it keeps dyeing. this only happens when im going down the motorway or dual carraigeway from 70mph upwards, i still have electrics but if i pull back the throttle it splutters and dies more, if i pull in the clutch it dies completely, i pull over and try to start it... occasionally it will start with choke but most of the time it does not, if i leave it for a little while i can get back on n start it (not easily) and it will run fine for around 4 miles. i had the problem about 2 months ago so i changed the oil, spark plugs and got the carbs balanced, this seemed to cure the problem but now it is back and its 100 times worse..
the only thing i can think it could be now is the coil??!
any suggestions as its nearly un rideable
cheers jake
