    We gathered together and I thought we give it a try. This is where 4-5 guys in the group becomes handy. Terry's bike volunteered itself to go across, and 4 of us piled around the bike to try and get it over ... 3 on the downstream side to stop it drifting away.

    We barely got a third of the way across before it was clear that this strategy wouldnt work. Even with three guys downstream of the bike, it was not possible to hold it against the current. I was out the front trying the manage the front wheel, and it got the point that I could not even stand up and began getting my footing washed downstream. Reverse orders were yelled out in semi panic and Terry's bike was hauled backwards to the safety of dry land.

    A new plan was needed.

    Where in this comic world did you dig up this elaboration of Siberian life? Please tell me it is a spoof of the ultimate kind or did I have too much to drink..........!!!??? I'm not sure if my laughter is justified or if I should be hanging my head in unbelief. Humor is the best medicine.

    I like a thin light pair of sneakers when I travel ... and I like all black ones, cause unless you are close up, they look like going to town shoes :)

    I bought these all black, chinese made sneakers, in a tiny market stall next to our hotel the first night in Kazakhstan ... for 12 bux.

    They lasted me the rest of the trip :norton

    What brand of mousse did you use? I've been running mousses for five years now, and I've never heard of hollow mousses.

    Mounting a mousse is far easier than most people think. It's just a matter of technique. Sure a tyre changer (not to be confused with a tyre machine) is easier, but it's quite doable without. Just watch the World Enduro boys change 2 tyres, oil and air filter in a 15 minute work period and still have time to polish their sponsors stickers. I find changing a mousse to be easier than a tube.

    This video is a bit of a stretch, but it does show the general idea of changing a mousse.

    Michelin M14s ... the benchmark mousses

    This is not a pic of my mousse that split open cause I didnt get any pics of it (but Terry was there when we took it out the filthy slimy greasy sucker and discovered it was ripped and hollow), but its another brand or rear mousse I found on the internet to illustrate the point .. its hollow. Fronts are solid ... like the illustration you posted. I am certainly no expert on mousses, but I do know the rears that I have used have air pressure in them and been hollow - I guess they do that to save weight ... Mousses certainly arent light ... saving 35-40% of the weight (unsprung weight) of the rear mousse will be a notable benefit to handling vs a solid rear mousse. But when the mousse wall rips allowing the air pressure out, its suddenly like riding on a 3/4 flat tyre. My ripped michelin didnt have the tongue of material like the mousse in the picture inside the hollow bit. It was just a hollow tube inside ... cross section of a donut.

    Now youve heard about hollow mousses :1drink

    Love your sig line :thumb

    Just a quick question about the tyres... I've noticed a bike with the I believe Mefo Explorer's and yours have a bit more of an aggressive profile. What about mileage?

    I also use the Mefo's on my DRZ as they are a good compromis but I sometimes miss a more aggressive patern for muddy tracks etc. but then I am also worried about mileage...
    Any comments?

    @ Walter; just trying like this as I don't know if my mails are coming through: did you get them about the tracks?

    What kind of a hairy creature is that? Doesn't look like a cow at all. Is it a kind of Yak or something? I didn't know they have them in Siberia. I thought they would live in the Himalaya only.

    But great pictures anyway!

    Got your emails, and I sincerely apologise for being late to get back to you, but it is on my to do list to sort something out there.

    Mefos win in the mileage stakes by miles and what surprised me was that didnt suffer notably on the BAM or ROB for grip ... I guess not much sand or mud, so they did OK.

    While we are talking of tyres ... The tyres (Heidenau K74) Terry and I picked up in Irkutsk and had now fitted, sucked big time. The back tyres had no direction stability and were constantly fishtailing all over the place. We both thought of going back to Zhigalovo to pick up our old tyres (My Michelin Desert and his Mitas E09 Dakar) to continue the ride with ... they would have been much better than the rubbish we were on.

    Hi Walter

    I know it´s difficult, but still a question about the motorcycle

    what would you recommend for a shorty like me (170 cm over all :1drink)
    a X Country with modification like Terry has or a
    X Challenge like yours

    thank you

    No problem M8!
    I can imagine that everyone is harassing you right now, but was just to be sure They arrived. I'll get your answer(s) when you have time!

    Thx for the Mefo's, you just confirmed what I experienced in the past and why I always still go for the Mefo's for any adventure riding, but they kinda sucked in the Sahara where the desert tyres would have been a lot better of course, but for mileage Mefo all the way.

    Allright, back to business now, so everyone stops asking questions, harassing Walter & Co, quoting on a pic from a thousand posts ago (I always wanted to be able to say that once...) and sit back and enjoy the narrating, pictures and Deus Mechanica!

    :freaky

    I got the feeling your mousse failed as a result of breakdown of its internal structure (not the hollow section!) causing it to lose its rigidity. It seemed equally soft and messy all round when we cut it up to get it in the waste bin.

    The internal structure breakdown presumably coming from 'mousse-fatigue' from flexing in use. Although it had not covered a great number of miles (a little over 2,000), those miles caused it to do a lot of flexing !

    I assumed the hollow section was not to hold air/gas beyond atmospheric pressure, but to reduce weight/material - leaving sufficient rigidity, until it broke down. BWTFDIK?

    I ran mousses in the Sahara a few years ago and whilst they were great in that situation I still think a stiff walled tyre with HD tubes and rimlocks does it for me and you haven't got that godawful slimy shitey mess when you eventually have to take it off. .

    When the time came I nearly bent the feckin' rim getting the worn tyre off with the Deserts I was running..:baldy....there wasn't enough give in the tyrewall to allow it to sit in the well and compress the mousse. Before you all chime in I'm sure it's a question of technique and me being a donkey. :mulie
    I almost hate to confess ( as someone will jump all over me) I took a hacksaw to it and sawed the feckin' tyre in 2 :mulie ..BE NICE TO ME!!

    Yamezz...Also loved the sig line about " Knowing your shit or knowing you're shit" :clap :lol3

    I must shamelessly poach it...

    Geir and I found that the rail bridge looked OK. It was time to introduce the guys to rail bridge crossings.

    It of course is useful experience, because by the time we get to Tynda at the end of the first half of the BAM Road and where we break off it to head north, we will need to cross a dozen or so more.

    After the bridge, we were making good pace along the road to Novy Uoyan when Terry suffered a scary mechanical failure at high speed. One of the bolts holding his bar riser to the top triple clamp snapped, allowing his bars to rotate separately from the front wheel. No steering !!

    He managed to get the bike to slow down safely. And we began strapping his bars to his forks. We would have to address this properly in Uoyan.

    Walter,

    The semaphore at the other side of the bridge shows a green light. Do you know what signaling system the transsib uses ? Most railroads in continental Europe use "locked-if-idle", i.e. signals are red if no train is running. The one to three blocks immediately ahead of a train turn green. When the train enters a block, the signal protecting it turns red again.

    Some railroads in the UK use "open-if-idle", i.e. all semaphors are green if no train is running. The semaphores for the block the train is in and the two or three blocks immediately after the train are red.

    If the transsib uses "locked-if-idle" then crossing a bridge with a semaphore showing green is not a good idea - a train will approach soon. If they use "open-if-idle", then a green semaphore doesn't tell you anything. It will turn red when a train has entered the block it protects, but at this time you have already seen (or have been run over by) the train... ;-)

    Cheers,

    FechFech

    Hi FechFech

    trains on the BAM are not such a big problem, they are not so fast and you hear them usually far enough or see them.
    I had only two encounters on a bridge, one was a kind of railbus (I saw him, but wanted to cross before him):
    [​IMG]

    On bigger bridges you have some kind of balcony, where you can wait (as in the picture).
    The lights didn't help me a lot for estimating the time to the next train, but I don't know their system.

    That pic is from Dirtbikeworld. It's actually a pic of a failed mousse. The mousse was solid when it was installed. As far as I know, the TechnoMousse supplier replaced two failures like that FOC because it was unusual. Without a picture of your mousse, I can only speculate, but a mousse can't really 'rip' when it's in place. What you probably saw were either melted sections (which is what caused the hollow in the pic above) or the result of butchery by an installer being rough on the levers - using brute force to get the tyre on, rather than technique. My guess is that the mousse was damaged in installation and was not lubricated well enough. Too much heat will melt a mousse and the melted area appears in pockets, rather than a general overall degradation of the entire mousse. These melted spots give the illusion of hollows.

    Mousses are certainly heavier than a standard tube. They are lighter than an UHD tube though. There's also a little more to the handling equation than just unsprung weight. Riding on mousses can have a 'dead' feel; which is actually a positive. While the valving in your suspension can moderate the action of the springs, it can do nothing for the 'air spring' that is in your tyres. Mousses don't bounce much compared to air tubes, so you get better traction, along with better suspension action.


    It sounds like you didn't have anything holding the tyre into the well. It's not a case of the tyre being too stiff - every tyre I've ever used has needed something to hold the tyre down into the well. It doesn't have to be anything specific - just what ever you can fit in there - tyre lever, chisel, screwdriver, bit of angle iron.

    Go ahead... I did!

    This is not the TransSiberian Railway but the BAM railway - constructed much more recently. The BAM was single track and the lights appeared to show green one way and red the other. I never saw any showing the same (or none)as in the system you described.
    We found no time or frequency pattern or warning of approaching trains (except horns - but that was another ride report!). All we knew was which direction to expect it from.

    The train in your picture is indeed a small local passenger one. The bulk freight trains along all of the BAM (west and east sections) are far larger. We worked out that their body overhang was to the end of the standard wood sleepers. There was not enough space for a moto between the train and the railing - other than in the short balconies that occurred every third or so section of the longer 'modular' bridges.

    Believe me, those freight trains filled the space, width and height.
    I know, in a manner very few do!
