Here's what I'm worried about. Let's say that these things are super-reliable, more so than a carbed 2T, and everything's all great. Now, fast-forward thirty years. Unlike most buyers, I actually intend to keep and ride any bike I buy for decades. Let's say that something goes wrong, as it inevitably will when you start talking about decades. The factory stopped making my particular engine twenty-five years ago, and none of their technicians know how to service them, because stuff changes and moves on. In other words, it's exactly the situation I'd be in if something went wrong with my Husky today.
However, when something goes wrong with the Husky, you go on the internet, find the number for the part you need, maybe ask a few dudes who know about Huskies if it's a particularly scary job, and fix it in the garage with the part, some bolts, and an Allen wrench. But what the hell am I supposed to make of something with all these computers and wires and electronics and crazy oil systems and finely-tuned sensors and automatic so-on-and-so-forth? Correct me if I'm wrong but it seems to me that maintenance on these sorts of engines is much more likely to be centered around the friendly local dealership than in the garage. Already, when something goes wrong with my dad's '77 Power Wagon he can fix it himself. But when something happens in the '98 Ram, there's a good chance he can fix it but also a good chance that he can't, and then it's off to the friendly local dealership. When the friendly local dealership stops catering to your vehicle, or moves out of town, or whatever, what are we supposed to do? Throw the thing in the garbage and buy a new one? I hold far too much sentimental value on both of my bikes to dream of doing that. I want to ride these things until I'm too old to ride anymore, I can't just get a new one.
That's my concern. If they can make these things such that you can fix the thing in your garage or in the pits given the proper parts, then I'll be 100% for it. In the meantime, I can only recommend that they simply dominate the street and leave the rough-ass off-road sort of work to a machine that can be maintained by a rough-ass off-road sort of person. I hope that Boyesen exhaust valve thing comes to fruition, because that sounds like precisely what the doctor ordered. Simple, mechanical, and effective. Maybe not as effective as an 8MHz computer (I like how they term it in millions of calculations to make it sound impressive), but good enough for a vehicle that's going to get pounded on by the terrain.
