i posted this in my build thread but i though it was cool enough to deserve its own thread. ill explain what all was done too.
i needed to make my mikuni 32mm carb attach to the stock air box so her it goes. all i needed to build this was a few inches of 2 1/4 exhaust pipe, a small piece of sheet metal, some automotive grade seam sealer (im sure you could use caulk too but the seam sealer will hold up better) and a large radiator hose i found at autozone.
basically, i realized that the 58mm inlet on the mikuni 32 was about the same size as a piece of scrap exhaust pipe i had laying around the shop. i tried stretching the factory boot but it ripped apart so out of necessity, i started this build. i cut the sheet metal to the shape of the opening to the air box and cut an angle into the exhaust pipe. after some measuring and marking, i welded the pipe onto the sheet metal
once i was convinced the welds were strong enough i spread some automotive grade seam sealer over the whole seam to be sure it was air tight.
then it was just a matter of drilling the mounting holes and spraying some primer on there to keep the metal from rusting.
but it gets worse, the radiator hose wouldnt stretch enough so i had to grab the die grinder and open it up a little bit. after about 20 minutes i had it all together and ready to go.
i got it all done in a few hours with mostly parts i had laying around and a $20 radiator hose. not bad in my book. hope everyone likes it. my advise, make sure your carb fits before youre committed to it, my carb "disappeared" so i had no choise and i had to retain the air box because i ride in a lot of mud and water.
