    Taking a ride up to the treeline

    Took the old girl up to 11,500ft today in an attempt to scout some old mine ruins and prospect a bit. It was a great ride - but I wasn't sure about the turn I needed to take to the "old mine" and ended up riding to the "new mine." Well, I got stopped at a gate with a sign that had the sternest warning I have ever seen! Needless to say I did not venture further! I did get a nice view of my intended destination from across the valley. I'll save that for another ride. On the way back I stopped along the North Fork of the South Platte River and was happy to see over a dozen nice Rainbow Trout in full spawning mode. Should fish well this Fall.

    Above St. Elmo? Mary Murphy Mine? A lot of the stuff I use to ride to 40 years ago has been restarted with very severe security.

    Yikes!
    Is that where they stored the old reactor fuel rods from Three Mile Island?

    Google is pretty cool! The mine pictured on that page is the same one I was attempting to reach, instead of Chernobyl further up the road!

    Reddave,
    I surely know how you feel in terms of the scenery. We're presently in Montrose CO and, spent a few days in the Ouray region. We did the Alpine loop, Amimas forks and Corkscrew gulch. Now, we didn't do it with the TW, it was with our '15 Jeep JKUR. That makes for very pleasant off roading and, also protection against UGLY elements which, we were provided with. But, I can see the fun in romping around on some of those trails with the TW. May I ask, as your TW traversed higher and higher in elevation, how well did it run? Did it seem to have any ill effects from carburation at altitude? I know our older Jeeps with carburation would spew black smoke etc. in certain occasions and, would also be quite hard to start up after they'd been sitting for just a short while. Just wondering.

    Scott, My basecamp is at 9000ft. I'm currently running a factory 114 jet that is old as hell and beat up so it's likely slightly larger than factory. I tried a 110 jet but it resulted in a lot of backfiring on deceleration so I switched it back. I feel that the bike runs just fine with the jet it has now. I stalled out once near the very top - but it was my fault as I lost my momentum on a steep hill climb. I stopped along the way many times and no issues with starting back up at all. But I must admit I don't have much confidence in my carburetor "tuning" abilities! So what the hell do I know...

    The stock jet for '87-2000 is a 114. The equivalent jet for 2001-present is a 126. I switch to a 122 jet above 8,000. The TW is pretty good at handling too big of a jet for altitude, but 5th will become useless and RPM's will have to be kept up. It will still start, though. For a day or two I would not bother, but more than that and I would change to a smaller jet.

    I don't have any holes in the airbox or anything like that either!? I did try a 110 jet but the bike didn't seem to like it. I attempted to find a factory 112 but had a hard time so I ordered a jet kit some from China some time ago... Honestly I was without the bike for so long at this point I'm just trying to get whatever riding in I can before hunting season. I will look again for a Yamaha 112.

    Finally rode up to the mine I was initially supposed to go - No radiation! Just an old shack...
