huge amount of smoke...

Yep done the valve guide seals

It’s got a new timing plate - condensers - points - coils - leads - caps and plugs

I’ll have another look when I get the chance..

Well puzzled

When trying to locate a problem I always look at the work just done .
You touched the whole ignition system , Hmmmmmmm..Look there first.......
Dont assume , Check it and coils too
Then look elsewhere

Would check for gasoline contamination of the crankcase oil.
Do the sniff test. And examine condition of the oil.

Good Fortune!

hey all, sorry such a late reply.
so had another look over the bike, was all pretty much fine...
one set of points was a touch out.
drained the tank, used a conditioner and ran new fuel...

still the same!

then checked the balancing! as i pulled the inlet rubber cap, 1/2/4 was filled with fuel like a bucket!?
then remember cylinder 3 was actually flooding up a week or so before. I pulled the carbs and polish THE BRAND NEW needle and seat.
that stop carb 3 flooding up , maybe it wasn't seating properly...

anyway pulled the carbs and done the same to 1/2/4 and its all been perfect! powers better then ever as well.... very strange but been a few weeks and still all good! no fuel in the inlet ca[s so maybe it was 'flooding' in a strange way.
