for some reason the pic's are not working on that link anymore, so here are a few of the wife's foreman to give u an ideal of what it looks like. the link has the info on what I used to build them.

you can use 2" all the way to the air box, but it will have to be reduced to 1.5" or the airbox will have to be modified to accept the 2" pipe.

Heat has never been a problem, just dont let it touch the exhaust. my setup is over 2 years old, maybe longer. if you look close in the third picture of the air box setup at the bottom on the frame, I install a tie-wrap to help hold the hose up.

H4 all the vents can be tied into one vent line except the carb vent. This will only give you two vent lines up front. you can run them up beside your snorkel.

Not all bikes but some will create a vacuum in the carbs starving it.
