Can the Main and Pilot jet on the '06 YZ450 be swapped without removing the Carb?

yes, but it's a pain...remove hot start, twist as far as you can, and you should be able to get to them.

I did it once, next time i will pull the carb out unless someone has a better method :thumbsup:

You don't need to remove the hot start. I took off the rear sub frame and rear exhaust for more room but that was my choice. It didn't need to be done but since I wear bifocals it was easier for me. :thumbsup:

I swap my main and pilot all the time by just taking the drain bolt off. The main is a 6 mm he and the pilot is a flat blade....it's not rocket science. I did get the carb off once by removing the top motor mounts. It was a little bit of a pain, but not too bad.
