No spark ?

I have tried starting my T80 after a standing of 12 months but to no avail it went though a stop start stage where it would run for a wile then stop swap plugs would do the same run a short wile and stop.
I now have no spark at the HT Lead, what do think most likely coil or CDI ? before I start shelling out. cheers Gaz

Right some thing weird going on as ive done nothing other than had a poke round the leads,And now it sparks and runs well? this is all good but what hecksgoing on don't want to goout on it and it fades what yer think coil dodgy?

Sounds like a poor connection, check the plug & socket connection from engine unit to CDI unit. Undo the connection spray it with switch cleaner reconnect & it should be fine.

Hi John I did all that, when I started the bike I could hear a ticking I think now it could be that the HT lead is breaking down.for a few quid I will replace the coil.
