the photo won't show for me. But if you're working on a CB650 the main jet is not removeable. Its a preset size and there you go. Dont' go changing the exhaust or intake too much or you'll play hell getting it back in tune.
If is too late for that, then you'll proably end up using a small drill to increase jet size that way. Good luck.
