Are you looking to get the bike to a)pull harder / cleaner at low rpm, or is it b)bogging in the low to mid range before it goes 'on the pipe' ?
If a), you could try retarding the ignition, but be careful about running too lean and this will sacrifice top end. A heavy flywheel is another option, I believe, but one I have no experience of, so won't advise any further about that. Different expansion pipes, reed valve spacers and jetting mods are other options.
If b), the bike isn't running properly, which could be caused by many things.
