New battery , plugs HT leads fine .
Any advice on why it suddenly now keeps cutting out on idea ...
Bloody dangerous at juctions that's for sure
It's been fine till I was gonna sell it lol ...
Coil maybe ??
 
Possible carburettor flat spot? Mine (845cc 1986) cuts out from idle if you press the throttle too gingerly. Answer at junctions : rev quite hard and slip the clutch in carefully. I believe it is quite a common problem with later R4s with Solex carbs.
 
I've had similar experiences with Solex carbs on other cars, including Dafs. It'd be worth checking there isn't an air leak somewhere, as this would cause a flat spot when moving off from rest, but wouldn't be obvious when driving normally.
With the engine on tick-over, try spraying some WD40 around the carb & see if the revs alter; if they do, there's an air leak somewhere! Good luck!
