A stock 500 will run great with 1 1/2 inch to the riser then make your riser with 2"..

i made mine out of 1.5 spa tubing. the bigger you go the more air and gass you need so if you go too big you will have to rejet.

I know this is the wrong forum but this is exactly my question! Will I need to rejet if I use 1.5" spa hose to the fender and then 2" for the riser? The bike is a 2000 foreman 450s, all stock. Thanks!

i used 2 in hard pipe all the way from the air box...runs great

you should not have to rejet for this set up. and i think u might have to use smaller pipe into the airbox. there is a write up on it in the how to section i think. u dont have to do it exactly the same, but it gives u an idea.
