Well the 2 stroke screamer is trying it's best to wind me up once again 
At the start of last week it ground to a halt with a complete lack of power, RAC called and the best he can do is tell me it's got no spark and tows it home
I managed to get hold of a new plug, plug cap, lead and coil, tried that last night, no difference
So what now
other than book it in somewhere

sorry to hear that. sounds electrical, and further back.. been out in the rain? im suggesting a bad connection further up the food chain, maybe the ignition isn't telling the bike its "on", dash lights?
do ou have an ECU you can disconnect and reconnect?
Dash lights up ok, it tries to start, and once in a blue moon it does
Not sure about an ECU
Going to see how much more trim I can take off and see if anything looks worn/broke/burnt out/etc 
you still on the cagiva, or did you buy a new bike, I thought I read that somewhere....
if its starting occassionaly, its possibly fuel flow. carbs are renowned for clogging (is it a carb bike??!!!)
clean the fuel filter (with petrol) or replace if its a sealed unit.
if possible disconnect the fuel pipe from the cylinder and see what its squirting like..

everytime I put a bit of cash to one side to treat myself to a new toy some thing happens to one of the other toys to lighten my wallet stooz said:

It is very occassional, well once to be exact

I'll give that a try, but if I've got no spark on the end of plug will it matter what its squirting like as without the spark it's not going to fire is it
sorry its tricky to diagnose on a website 
could be either. have you actually seen the spark? hold the spark out (with some rubber handled pliers) - and start, it should spark across the gap rapidly.
if its sparking it should light the fuel. if there's no fuel....
if its fuelling and sparking, it could well be heavily flooded by now, removing spark should get warm air drying out the cylinder.. the cranking while you watch the spark should spit any stuff out too..
fuelling is often a git, more likely than a spark issue, hence my suggestion.
to rich -- too lean.. to far and it wont run at all..
often people turn up the fuel to compensate for another problem ; too much air.
its no wonder everything has gone injection, carb setting is such a dog..

Now I'm getting wound up
Change the HT lead, Spark Plug cap and Coil, no difference, change the CDI unit (whatever that is) and we have spark
Take it for a ride round and it seems fine, if a little bit sluggish on take off, ride around for a while, and put it away.
Take it out the next day and nothing, it would not start, pop the plug out again and thats fine sparking away, battery fine, petrol should be fine, so whats up with it now
It's one step away from being found burning on the local Chava housing estate

hooray a spark!
if its been sitting around for several weeks with the plug out, sounds like the petrol/carbs/injectors could have got clogged as per my original diagnosis.
normally the piston "area" is a pretty sealed unit, moisture gets in quick, so does air to dry it all out...
see what options you have in terms of flushing the petrol?
