Have a little faith Jack! I actually was running 13/26 with a stock sized rear tire, and the bike had no problem breaking loose on anything except pavement. On pavement, you couldn't keep the front end down!

Now, I've extended the rear about 1.25 inches and pushed the front end out a little with the new Teixeira Tech A-arms, so it shouldn't wheelie quite as bad, but it will probably spin a little easier. But the tires I'm going to use (for now at least) are some little bitty 18x6.5x8 Holeshots that I bought years ago when I first put it back together with your modified motor parts. These are the smallest and lightest 18's I've ever seen. I don't even think they're 18" to be honest if I took a ruler to them. With the 13 tooth sprocket I had, these tires would have no chance of hooking up if you fully pinned it. I actually put the taller stock tires back on with aluminum rims to gear it up some.

Also, we're not on an MX track most of the time. I agree, a 14 would be too much there probably. But it’s nice on a gravel road cruise to not have to wind it out too much.

I'll play with the gearing/tire combo a little. I just want to try a 14 once with these tires. I'll let you know how it turns out.

Also, we’re planning a trip in May to Little Sahara sand dunes in OK. I’ve got some Kenda Gecko paddles for it. They are a little taller and heavier than the little holeshots, but in the sand, I think it will still do ok due to the ability to spin. But sand does rob a lot of power, so I’ll have about 3 or 4 different size sprockets with me on hand. It’s easy enough to switch out, so we’ll play with it some the first day to determine what works best.
