I would just bypass it. I can't find any anywhere myself. You'll have to run a line from the tank with a filter on it to the big nipple between the 1st and 2nd carbs, and then put a cap on the smaller nipple in between the 1st and 2nd carbs. Then you'll have to use the fuel petcock to shut it off, so that the gas doesnt all run out of the tank while you're away from it.
