Yes. The original trail tamers were an Earles design.
There is no way to "safely" unstick and engine without removing the head.
Yes, I agree it's a Rogue, and not the close relation Cheyenne. Good job Pat.
I don't know what's been done to this bike, but from what little I can see, it's the cleanest Rogue I've seen. There were quite a few of them made by the way, and not strange, or rare. They came along later in the mini bike evolution, and the production run wasn't that long. So Cal. That side car is intriguing. It almost looks production. We need more and better photos. Someone did a lot of work here, including the engine. If you were down the road, I'd get the engine sorted. Shipping kills. Great score if you bought it.
