    Here is a good use of wolfman racks to support an additional tool tube. I will run some steel cable ties around for added security.

    Oh, and the exhaust wrap wasn't really needed, tool tube stays reasonably cool.

    Thanks for the info Lex. Since I ride all winter when the roads are dry, often at temps in the high teens and 20's F* and sometimes down in the single digits, I'm happy to spread the bad word about Bridgestone. Here's the pic I lifted from the guy's post.

    I can't believe that this is the official Bridgestone response.

    I believe it. Summer tires shouldn't even be stored in temperatures below freezing. They become brittle and slippery, like glass. Then they can shatter and/or crack, as you have seen.

    A lot of people bad-mouth all-season cage tires as not being capable in the snow. They're not designed to be snow tires. They're simply designed to not become brittle and slick in freezing temps, while not vaporizing when heated up like many snow tires do. Moto tires are similar. If you see freezing temps, use tires rated for that.

    I've lived in Colorado nearly all my life, and I've never seen a tire, moto or car, that froze and broke. You may be right but it gets below freezing here a lot, from Sept to May.

    Growing up in PA seeing temps below zero for weeks at a time- I have never seen a tire freeze. I'm calling bullshit.

    So no mention of motorcycle tyres at all.
    Picture of one cracked tyre and all Bridgestones are bad?

    It's like the "All Trailwings are Deathwings" crap.

    It also looks like it would have had to be a combination of extreme cold and a pointed impact on that road tyre...

    Don't know about tires freezing, but my F-250 4x4 (235-16 Toyo load E) and toy hauler (235-15 Toyo load D) had flat spots on them for about an hour of driving after being parked over nite at Teslin, Yukon when the mercury read -72°F with strong winds.

    We drove jogging speed for several hours to get out of that cold valley to warmer places. Several valleys over it was only -42°F and we could pick up speed. The locals said to not go very fast because springs or axles could break when hitting chuck holes etc. One of the trailer springs did break on the way home... from too much weight (Toyota Land Cruiser in the toy hauler and lots of carpenter tools).

    Glad that spring broke behind the axle. A piece of firewood was inserted between the axle and frame and wired in place. That field repair lasted several thousand miles to home. New springs were installed there in a warm shop. It was a nice month long road trip to Anchorage for Christmas to visit family and picked up the Toyota and tools.

    "Summer tires?" Jeezum -- once again I've heard it all. Summer tires is as big a crock as the old prank of "winter air." Or the carpenter's prank of a "board stretcher," or the plumber's joke about "left-handed" pipe wrenches.

    Dude - somebody has pee'd on your leg and convinced you it is raining.

    The defining difference between a street tire and a rough terrain tire is the thread pattern. Rubber compound (softness or hardness) primarily impacts thread life (i.e., miles derived under use on the intended surface).

    Off-road tires grip the terrain foremost due to thread pattern. Ambient temps have more influence on the terrain than on the tire. IOW, the terrain can be hot, dry, wet, or mushy, or frozen. The tire does not know the difference.

    The thread pattern on street tires grip better on asphalt due to an increased contact patch. Rubber compound in street tires responds to increased temps due to impact stickability on asphalt surfaces, so hotter is better up to a point.

    But all that said, the rubber does not know the difference in terms of low temps and cracking such as what was shown in those photos.

    Those tires are either defective from the factory, or unbelievability old, but cold did not do that.

    That's kind of my point as well. In the teens here during the winter and no "broken" tires.

    like others, Ifinally replaced the petcock on my IMS tank with the Yammie Raptor part. All was swell until recently. It leaks.
    And, I can't really tell for certain where the fuel is getting by; I replaced the main gasket with a new one but it still leaks. Seems to be seeping around the seal of the valve itself but I am not sure.

    if any of you have experience with this pls advise.

    If I have to buy yet another petcock, which one will actually work?? :ear

    I had an issue with my IMS petcock on my old DR350SE. I contacted IMS and they sent me a new one for free. That said, they sell replacements for $20 (last time I checked). That's pretty cheap.

    EDIT: I see you've switched to the Raptor unit so you've modified the tank. The IMS unit won't work now. Never mind.

    This might help, although Acerbis 5.3:

    P.S. I think someone recently said that a gasket cut from a tire tube would hold up to gasoline, in case you have to make a gasket with a larger surface area.

    ok.
    i guess the answer is "its bad".
    like I said, its not a gasket issue - at least not a mount-gasket issue.
