i took my kreidler and ported the transfer ports a bit and the intake and exhaust, but not the actually holes in the cylinder.
i noticed its harder to start, and it now goes about 4 mph faster. How the heck do you get to the ports on the inside?

carefully
What I've heard is that you don't. The ends of the port on the cylinder side get left alone, too much risk of them catching a ring if they get messed up. If the cylinder bore is chromed it also could flake if you try to enlarge the port.
But I could be wrong.
success then, congrats!
you should plug chop if you haven't, and re-jet if necessary.
yeah you've increased air flow and now your engine breathes better, you'll probably need to upjet slightly to get best results
we all port the "holes" inside the cylinder all the time. thats how you do a port job. there are quite literally hundreds of threads on this many pages long. its totally possible, just takes some forknowledge and the right tools.
do a search on porting and port job. should be enlightening. also yeah, anytime you add performance to a 2 stroke its gonna need more fuel. do a plug chop to be safe or upjet and see if you 4stroke.
oh did i mention it has a 10 bing?
it has a 72 jet in it right now and its pretty much spot on.
I would say that carb is really holding you back. If you were to step it up a bit you might see more of a difference.
