I would go 5 over stock main jet if you keep the
stock airbox. Otherwise go 10 over stock. That's
where mines at and everything runs perfect.
If you have the newer carb- run a 150 main jet.
Never heard of that back pressure thing warping
valves, but one thing you can do for some back
pressure because I think the bike likes a little
tiny bit of backpressure is drill a hole at the end
of the pipe and bolt in a 3/8-16 bolt at the end.
That should create enough back pressure. But you
may not need any back pressure. My bike ran much
better with very little back pressure, compared
to with a 4 inch modified baffle, which I could
barely keep up with people with.
