Spark plug removal.

might be worth mentioning that the stock mudguard doesn't offer the front plug much protection from water so if you've been splashing around in puddles it's probably worth checking the front plugs dry first. Would fit the symptoms.

Thanks Sayani!

Gracias! - that is a possibility!

The other thing which can cause these sort of problems is sticking choke plungers.
If the plugs look very black and sooty, that could be your problem. Lots of discussion on this topic in the past (when curveys ruled the roost), try a search on "choke plungers" or similar.

curveys still rule tbh

Will it be obvious embee?

On a curvy, the side panels also push onto bosses on the sides of the radiator.

To pull these off, just remove the rear-most bolt on both side farings and pull the fairing away from the radiator. Do this in the area of the boss and very carefully!

Maybe, maybe not.

The rear choke plunger is easy to get at, it's on the right side of the rear carb. The screws can be difficult to remove if they haven't been out before and lubricated. A gentle tap with a small hammer can help.

Usually you'll find white corrosion around the cable end and choke plunger when you carefully withdraw it from the carb body. It doesn't take much to prevent the plunger from returning fully when the choke lever is closed, the spring is quite small.

The front one is much more difficult to get at, and really requires the carbs to be taken off the engine, not a difficult job and worth the effort.
