Upjet 5-10%. Buy a pack of jets for your carb, start rich and work your way down until your spark plug is a nice brown colour.

To change the jet you need to open the float bowl on the carb (Bit of petrol will pour out), undo the float bowl and simply swap the jet for a bigger size, then refit it all. Then use the kick start until it starts.

To check the spark plug you will have to run the bike at full throttle for a while and turn it off, pull over and check the colour.

Black = rich.
White = lean. (What yours is now)
Brown = perfect.

Two strokes are very specifically tuned with exhaust and air filter. If you change either then it will run either rich or lean. As said you might need to upjet, but you might also need to replace the exhaust too... short answer is that it's not worth it.

stressing me out. ive got to get a new exaust

Youve changed the air filter so more air can now get in... so you need to upjet the carb to get more fuel in to match...

the ideal ratio for air to fuel is 14:1...
