    IZH 350 drawing

    I used this drawing for shirts for the UDCN 🙂

      I dug this out of the archives. ИЖ-350:

      In 1945 a team of experts from Izhevsk machinery plant (ИЖ) was sent to Germany and as war reparation got all technical documentation and production means providing up to 35.000 motorcycles/year, and there it was there, DKW NZ 350 model. It was not only Germany supplied technical papers, parts , but also German specialists including main designer of DKW factory Herman Weber.

      The USSR People’s Committee for Weaponry head D. Ustinov cheered up plant’s workers: “You make weapons well, intelligently, but know nothing of motorcycles, that’s why I prohibit to make any changes in them. Copy them as they are, when you know what’s for what you will introduce your changes, but not even a nut now!”

      That was how a copy of DKW became a production base model for many years till the plant’s closing in 2007 including majority of IZhevsk road motorcycles. 2-stroke, 1 cyl., 350cc engine with 72x85mm dimensions had 10.5 hp, left-side foot lever of 4-speed gear changing mechanism was doubled by a handle on right side of fuel tank. This was first mass-made model for the plant with totally 108,000 made in 6 years.

      (ИЖ is famous for its Kalashnikov rifle)

      Make a nice shirt John. 🙂

    Some help needed, I have a “Dneprglide” gearbox with an fault !
    In second gear it looks like it goes faster and slower constantly.
    So I shift very quick in third, no problems at all.
    Mentioned causes, takes another gear the same time, oval gear, friction with another gear !
    How do I find out what the problem is, and more how do I fix it !!

    PS another member of the UDCN has the same problem in third !

    for “Dneprglide” gearbox MT804, first thing to check is that the automatic declutching mechanism (foot clutch) is adjusted properly as per the owners manual. If it is not adjusted properly all things can happen! (jumping out of gear, even the gearbox can go out of order!).
    You say “In second gear it looks like it goes faster and slower constantly.” How do you mean?
    If you have “friction with another gear” it might pay to open up the gearbox and inspect it thoroughly.
    Hope this helps John. Anyone else got a comment on this plz?

      With faster and slower I mean exactly what I wrote, moving faster and slower forward.
      Like having an fuel problem 🙂
      Yes JD, I have to open up the gearbox, but I want to know where and what to look for !
      Thanks for your input.

    Try this… (with some humour 🙂
    Automatic declutching mechanism is set up perfectly!? OK>…..
    1. Warm up the engine. Try and run the gearbox thru its paces, listening to it thru a sounding rod (diagnostics). Hear anything?
    1a. Take out the spark plugs and do a compression test. Might as well as you’re at it 🙂
    2. With the gearbox in NEUTRAL turn over the kickstarter several times, feel/listen for any hardnesses/touching/slowing/friction between parts (eyes closed),. It should all turn smoothly.
    3. Put the bike on the workshop stand or raise the real wheel off the ground.
    4. With the spark plugs removed you should be able to turn the motor/gearbox/final drive smoothly.
    4a. Turning the rear wheel by hand, several times both forwards and backwards (reverse :-), try turning the rear wheel by hand several turns. each time in I. II. III and IV gears selected, again feeling (with eyes closed!) for any frictions in the mechanisms. Take any notes.
    Note: Gearbox MT804 has two (2) neutrals, one between I and II (main neutral), and the second between III and IV (high speed coasting neutral). All should work silky smooth.
    Didn’t call it Dneprglide for nothing!

    re: “moving faster and slower forward” ~ Steve Wiggins says sounds like a slipping clutch…

    1. John

      Thanks for your support Steve but definitely not the clutch ! Only happens in second gear. It’s really the gearbox, I was hoping someone recognized or had the same problem. And did know what it was and how to solve it. but it seems I have to get the gearbox apart and find out what the cause is!


    hi–TOP SITE! we share a similar hobby.
    I’ve got some info too—can you send me your email address.
    regards Adrian Vergison. (Sydney–Oz) A.K.A. Ados.

    Giday Ados (Adrian)! Cat (our site admin here) is in Holland but i am in Sydney-Oz 🙂 I just did a Google and quickly found you in the VVCMCC. I love your 1938 BMW R51 “SPORTRAD” !!!! Congratulations on Best Pre-War AND Best European! People like you might know people like Barry Bligh and Overlander Equipment . You might even know my mentor Vin Minogue in Melbourne. I got to ride his 4-cyl. K-800 Zundapp once around the block about 35 years ago! (the highlight of my life!). Vin is in his 90’s now but his wit is sharper than ever!
    I hope you can get in touch with Cat! He might add you a page here in Pandora’s Box! 🙂
    Cheers~! JD
