    From a ride I did this weekend with some friends who were on quads. This is the only pic I have as my battery died while out on the (snowmachine) trail. I friend is supposed to email his pics from the trip to me. Mr. Bigwheel was kind enough to let me use his 25" studded Mud Buster tire which proved to work much better in the snow than the 22"er that I had been using. The BW did well as well as the quads in the snow, and got stuck about the same # of times as they did, only it was easier to get the BW unstuck.

    lol, I never noticed the dog in that pic. I swear he is not a relative of mine even though we may share some common DNA.

    Röhrich,

    What museum are you going to display that BW in? Surely, you are not going to ride it through dirt, mud and bugs, are you?

    Shercoman,

    My intent to photographically document the Tri-Z conversion on Cliff's #2 ended up alongside my New Year's resolutions. However, some salient points are thus:

    1.) The triple clamps bolt up without any modification. I just use the opportunity to replace the loose ball bearings on the top with a tapered bearing.

    2.) The BW wheel will bolt up to the Tri-Z hub. You will need a Tri-Z axle, since the Z axle threads into the bottom of the fork tube (which is a smaller diameter hole than the nut used on the BW) The '85 and '86 Z axle are interchangeable.

    3.) The non-brake side axle spacer from the BW will work on the Z axle. However, You will need a Z spacer on the brake-side for the conversion. The BW doesn't use one at all on the brake side.

    4.) The easiest way to get the front brake operational is with a Tri-Z caliper. Sure, they are quarter of a century-old, single pot, three wheeler brakes, but they bolt right up and can be used without any fabrication.

    This is a link to a machinist who put a disc on the rear of his XT225. It might be of some interest.

    Look what followed me home. That's right, a pink and white RT100!

    Oh, and the BW350 that's in front. It's a bit of a project so I'll be seeking help once I get started on it.

    Mr. BigWheel,

    Are there multiple formats for the bearing upgrade? The ones I see listed online for the Tri-Z look like regular sealed bearings, while the ones listed for the BW's are needle bearings. Which style have you been using?

    BWSwamper,

    The Tri Z and BW have different applications because the Z's steering stem has a larger O.D. than the BW's.

    All Balls lists the BW at: http://www.allballsracing.com/22-1025.html

    and the Tri Z at: http://www.allballsracing.com/22-1019.html

    So naturally, get the BW part if you are using the BW triple but get the Z part if you are doing the upgrade. Both of these kits are just tapered bearings that replace the loose bearings at the top or the BW stem. They do not include a bearing for the lower part of the stem.

    You have to knock out the old race and install the race to accommodate the new tapered bearing, but it is not a very demanding task. I did it recently while watching Cliff spend two hours replacing the left foot peg on his 350.

    He still claims that it was the CDI failing that made him take so long to get the foot peg back on.

    Regards,

    Mr. BigWheel

    Duster11,

    That is a pretty good looking bike for a "project." That looks better than some of our running bikes. More pictures will be expected, of course.

    And if, for some strange reason, you decide you need to stud the tires on that bike, here is the primer:

    I am curious how much this 12" setup weighs? Mr. Bigwheel and I measured 3 different combos of tires and wheels and came up with a 10# difference between the heaviest and the lightest.

    I'll weigh the thing before I swap them out. I'll post a photo once I have it installed.

    This is being posted solely to prove that I made it considerably higher up the B-29 trail solo today than Cliff and I did on our last attempt.

    All by myself.

    So there.
