  1. Lorenzo,

    thanks a lot, this helps with making a speedo replacement!

    Washer has found to it's correct place already and I just found a sleeve which goes somewhere around the speed drive which obviously fell down and rolled away when I took the wheel off the bike...

    I assume it will be perfect again when I fit that sleeve AND have everything in the right order 😄

  2. So, much better niw if course, but I am still unsure about the order and especially number if “things” in the course of the rear axle.

    If someone could check out his rear axle (especially around the speedometer drive) it would still be highly appreciated

  3. Hi,

    just replaced the wobbly wheel bearings but the rear wheel of my 199 Sherpa is still not fixed properly when I fasten the wheelnut. 
    Washer behind wheelnut touches the thicker part of the axle after the thread before the rear wheel is fully tightened.

    Of course had I checked the parts book but I am still unsure if therr is something missing.

    I have, beginning from the right.

    Head of axle

    washer

    chain adjuster

    wishbone

    speedo drive

    wheel bearing 

    distance

    wheel bearing 

    drum brake hub

    thick washer

    wishbone

    chain adjuster

    thin washer (in diameter if thread)

    Nut

     

    Am I missing something?

  4. So, she runs!

    It was the missing earth wire to the green cable.

    Either it was missing or I took it iff by mistake because I thought it was for the lights.

     

    However, thanks a lot, great forum, super quick support ?

  5. I totally agree, that’s what puzzles me. As I had bought it spark-less I cannot be sure if everything is put together correctly. But at least to my recently acquired knowledge it seems so.

    I replaced the coil as the ht lead was totally knackered (and I wanted a quick solution...)

    Points received a cleaning before I put them in

    Killswitch was disconnected (that’s the “flying” lead on the pic of the coil

    The new red cable is the elongated black wire from the magneto

    I planned to extract the lighting hence the absence of some of these cables!

  6. Ciao,

    Right, this wasn’t very detailed:

    I bought it with no spark and as I am usuya very good mechanic I was convinced it would quickly return to operation...

    replaced the HT coil

    points are set to 3mm before top dead center

    0.40 mm gap

    I am measuring at the cable terminal below the steering head 

  7. Hi all,

    I cannot squeeze any spark out of my newly purchased Mod 199 350

    Coil, condenser and points are new and set correctly 

    At first I suspected a short to ground but after two days if thinking and tinkering it seems my flywheel isn’t sufficiently magnetic any more.

    Even when turning the crank with the electric drill I only get 3 V AC out of the magneto 

     

    Any ideas what else could be wrong and how to overcome or test that further?

  8. Hi,

    while inspecting my newly acquired Sherpa 350 mod 199 I noticed a wobbly front wheel. After taking apart and comparing with the parts book I noticed that I am missing a spacer.

    Does anybody probably have the needed width of that spacer so that I can make one?

  9. It cannot be too many of course, keeping the overview is just challenging some times.

    However, the pure motorcycle Sahara trips where done on KTM Adventure 640 and Rallye 690 Factory Replica. The ones with Land Rover as luggage and fuel transporter where with GasGas EC250 and KTM 450EXC

    The latter for very sporty riding in the dunes of course 

    The Rallye for insane speeds on the pists and still quite remarkable dune rides. The Adventure mainly to burn her down and sell after that trip

  10. Hi all,

    I am not completely new to trials (had two in the past) but new to the forum and new to classic trials. Just bought a Bultaco Sherpa T350 from 1978. I own a lot of motorcycles and it’s save to say that I am proper motorcycle and mechanical stuff nut. Born already 49 years ago do I still feel best when wrenching or riding.

    I had done and still do almost everything which can be done on two wheels, from crossing the Sahara, to proper hard enduro, race track, bit of trials, travelling or just bashing around.

    Wherever possible I prefer older stuff over the new, on bikes but even more on cars and all the other small wonders of life.
