I recently made a few mods to ol'trusty, including a locker in the front and a snorkel. the snorkel is a 1 1/4" hot tub tube and does not deliver enough air. I have water proofed everything else and do lots of river riding. I hydrolocked it once last year and decided the snorkel was necessary. I used the stock inlet to the air box cut it and gooped the snorkel into it then snaked it up and out the right side. it seemed to work before I attached it in place. I may have enough room for a larger tube but am wondering if that will solve my problem. Do aftermarket snorks require a carb adjust? does it need to be smooth tube vs.ribbed or just a straighter run? any advice welcome.
