I have 03 klx 110 with stock carb aftermarket filter and I recently drilled out the exhaust now the bike runs awful from 1/2 to full throttle all the jets are stock did not know if anyone had anything I could try I am trying to get the most power from it with it still being quiet

I think I'm running an 88 main jet with stock(drilled out) pipe. Runs good, still needs a big bore kit though.
