I am having a hard time finding the correct tube for my wheelers. I have 1981, 1982, and 1983 Honda ATC 200s. Some split rims and some one piece. 25x12-9 tires. At one time years ago I purchased a Kenda tube that worked well in the split rims. (the valve stem lined up with the valve hole). Since then all the tubes I have purchased have the valve stem in the wrong spot. I tried a call to Kenda, but just got the "all 25x12-9 tubes fit" answer. Can you folks give me some part numbers or links for inner tubes that actually fit? Den

I've run into this too. My best solution is to drill another hole for the tube valve stem. I'll install a tubeless stem in the original hole to keep the crud out. If you use this method, start small. It's easier to make the hole bigger than it is to make it smaller. Also make sure that there isn't any burrs left over from the drilling. They'll flatten a tube in no time.

Thanks 350, I have considered that solution for the tubes I already own and am aware that the hole size is 11.5mm or 29/64". Having owned a tube in the past that fit, I know that the correct tube is out there. I am sure others have struggled with the same problem, I was just hoping that someone on this board remembers the answer. Den

Bringing this back to the top with a little more info. Hope someone has the answer. Den

The one piece rims are 9" (23cm) wide (inside bead edge to inside bead edge) with the stem hole 3+3/8" (8.5cm) from inside bead edge.

The two piece rims are 10" (25.4cm) wide, with the stem hole 3+3/4" (9.5cm) from inside bead edge.
