Do the same with the jets. Keep carb cleaner away from all the o-rings and such. I would just replace them while you have it apart.
I like to keep everything segregated to the carb of which it was removed but I don't know that it is a requirement. The carbs have to be absolutely spotless. Three are several threads on here showing people doing this. Also there are lots of youtube videos showing how to do it. It can be an intimidating task when you start because all of the parts. But it's pretty simple actually. It's just tedious.
ok great. And if that doesnt do the job..?
I shall dig into the engine then

Ok disregard the arrows.. but do you see the 4 4mm tubes at the bottom of the airbox.. should i connect those to my pod filters to simulate it as an airbox or do i leave it tubeless?

I see the tubes. I'm not sure if you should or not. I don't have any personal experience going without an airbox. I would suggest to try it both ways if you can't find your answer archived here someplace.
