You can use steel shot with a choke anywhere from cylinder to modified, i wouldn't recommend using steel with a improved modified or a full choke.
186 hp
2006 CRF450R=50HP, my 06 dyno'd in at between 39 to 51 within seven tests so I'd say a straight 50 to the back wheel is the correct HP for this machine
Yes- that is what the poly-choke is for.
They usually use a modified (medium) choke on the 870, unless it has choke tubes.
