Speed Triple Misfire

Hi just bought an 05 speed triple 1050
Low mileage took it out and took it through its paces today and its developed a low rev misfire underlined upto about 3k revs tried a bottle of injector cleaner .will try new plugs tomorrow .any more ideas???

 

Probably a bad plug, I’d replace them first.

 

Any improvement?

 

Put new plugs in today and seems better but only pottered around in the wet so will give it a blast when its dry and hopefully it's all good
Many thanks
