The Hot Cams Stage 1 cam for our Honda XR650R motorcycles sounds to be exactly what I'm after in power. In the past more power equaled more fun. That still holds true today, but to a lesser extent for me. I definitely will have to put in the Stage 1 cam if the bike shows wear in the top end anything near what yours had. It's good to know there is still more good power to be had even if I don't really need it. As far as that auto-decompressor, I only use it because that is all there is on my xr500r. It is a real pain trying to use to bump start the 500 even when it is on top of a good hill.
I've been an Oregonian my entire life. I've barely moved a mile from where I grew up, but the change in population, traffic and rat race in general is extreme to the point of looking to move when I retire. I love Eastern Oregon, friendly people, beautiful country, you live in the outdoors. There are drawbacks of course or everyone would be moving there. All of my riding in Eastern Oregon is in conjunction with camping, which was in the vicinity of the Strawberry Mtns this year. I look forward to doing more exploring of the Steens and even the more remote Trout Creek Mountains someday. We generally ride out there on the remains of old jeep trails, roads that are no longer on any modern maps and sometimes I use Google earth to look for ways in and out of certain areas.
My son led us into one area last year where we didn't get our bikes out for 3 days. We had to hike out cross country (I have a good sense of direction) for over 12 miles much of it as the crow flies, getting back after midnight. That was a bit reckless and won't happen again. I used the remaining bike at camp to explore an alternate route coupled with quite a bit of hiking to get the bikes out. Western Oregon as you know is a completely different climate and very different riding. We rode in the 70's out in the Burn, now the Tillamook Forest. Where we used to run in the Trask is now gated since Weyerhauser bought out Willamette Ind holdings there. We ran a lot where the Trask Mt ISDT was held, and would seldom see another rider. The best riding I ever experienced. I'm not sure where to go now. I'm trying to get 2 of my old riding buddies to ride again, One of them has an 80's TT600 and still rides occasionally, and may know of some good areas and the other still has his TT500, but hasn't started it in a very long time. Interests often change, but I will keep trying until I hear a no answer.
I have never ridden the dunes, but my stepson who is into quads has been asking me to come. It is not close and finding that much travel time has not been easy.
I'm interested in what you find when you dig into the 84 XR500R. It has a totally different engine than my 82 model. Did you know the 82 xr500R has a reed valve? I have been experimenting with the rear suspension on my XR500R. I've given it more sag and in doing so lowered it quite a bit. It was sprung too stiff for my weight and while much smoother than the ol BSA, I think I can make it fit me better with some tuning, but I will sacrifice some comfort for good trail riding ability.
The reason I went with the 82 xr500r over the 84 XR350r was the over heating factor. I was afraid I could burn it up on slow trails in the summer heat. It has adequate power and a much better front brake, but I thought better suited to running fire roads to keep air moving around the engine. I should look into jetting but it does run smooth. I don't remember if I ever checked the plug. I'll have to do that. You can smell the heat coming off the engine when every other bike with us is normal.
