Use a die grinder and raise the top of the port
But be careful you need to do it right other wise your cylinder is trash

if you're asking this question then you don't know what the eff you're doing so don't try it or you'll ruin a good cilinder.

You should probally go to a local engine tuner or motorcross expert. Because its very easy to go too far and mistakes arent easy corrected.
