What is your experience with Yamaha?

  • Hello, I'm playing with the idea of ​​gaining a wr 400!
    What are your experiences with the durability of the machine?
    Look for a low-maintenance machine that you can take for everyday use (short asphalt stretches)!
    How often should oil changes be made?
    What else should be done with the service?

    Greetings Pepe69

    Everyday life = short asphalt stretches = durability paired with low maintenance is a contradiction in terms as it cannot be bigger.

    My opinion, sorry

    point in and out again under zuch

    This message was poked into the end of an exposed fiber optic cable with the help of a flashlight

  • have driven one for 4 years with almost 8000 km on the clock.
    never valves set. they were always on target.
    would have never a defect in the 4 years. it also depends on the maintenance and your skills as a screwdriver. some get everything broken.
    I also drove motocross and enduro competitions with it. but only connecting stages on the road or on the way into the area.
    oil change every 10 hours or max 800 km, depending on use. the engine will thank you.
    there are also quite a few drivers who use the 400s as sumo and have few problems.
    But one thing should be clear to you. it is still a sport and not an everyday enduro.
    You can also find some information here: http://www.wr400f.de/

    I can definitely recommend the box.

  • I also drove the WR for 2 1/2 years, mainly on the cross track and enduro competitions, was twice in Tunisia where I had to cope with a few KM of gravel road and that at relatively high speeds.
    I never had engine problems, it ran like one until I sold it.
    I only had to adjust the valves once, otherwise just check them and do them well.
    I can only advise you to change the oil once too much rather than neglecting it, otherwise you will pay dearly for it.

  • Weren't there any transmission problems with the 400s? -> Forum search. Kind regards

  • Weren't there any transmission problems with the 400s?

    nope there wasn't, there were clutch problems

    which should no longer occur because the boxes now all have a few days under their belt and the previous owners should have clarified this problem.

    What should be noted, however, is that you should take a closer look at this faked baffle plate in the carburetor

  • I only know about transmission problems, I haven't heard of clutch problems.
    When it comes to transmissions, certain Bj are said to have been hit particularly hard.

    My friend had gone crazy with his WR400 from 00 '3 gearboxes on 6000 km.

    I drove my WR426 from 01 '4 years and 11000 km without probes and then it wasn't finished, I don't know what it was doing with the new owner.

    I don't know if it's really because of the Bj. Simo Kirsi once told me at the November Käsan in Hoope that those with the YZ from 00 'had extreme problems with the gearbox and that he was fed up ... At the Käsan was already riding a KTM at that time. They drove the yams better, he said, but too sensitive ...

  • I bought a new WR400 model 99 in 2000 and drove my motorcycle for about 5000km on cross-country tracks, enduro tracks and field-forest and meadow paths for 4 years. The motorcycle ran without problems and flawlessly except for a gearbox damage (3rd gear), which came at approx. 4500 km. At the same time I had a YZ426 model 2001, which was brutally driven in supermoto and motocross. There weren't any problems at YZ. I checked the valves once a year, which were always correct, and otherwise the usual maintenance such as air filters, swing arms, steering head and deflection bearings washed out and lubricated, which is also a matter of course. With the YZ I have a fully synthetic Motul V300 15/50. and with the WR Motul 5100 15/50 partially synthetic. driven, which I also changed every 8-10 hours. All in all, I would say one of the most grateful mopeds, which has great engine characteristics (gentle down and turning nicely upward), which is of course ideal for enduro riding. But had to sell both because I needed something for my heart again and bought an SX525 and an FE501, which are also good mopeds (just with more steam: devil gri.
    On the subject of gear damage:
    I wasn't surprised because I almost always drove on a hard cross track and that was inevitable. Wouldn't necessarily say that the WR400 was a disease but just wear and tear (the driver of the gear wheel is round, which is why the 3rd gear just slipped out. When I disassembled the engine myself, I was over the great condition of all other parts amazed.
    Conclusion: great engine, chassis too soft for motocross, a bit too heavy for world championship runs (it's also a bit older: biggrin :)
    Oh yes, the accelerator pump on the carburetor occasionally had to dismantle, clean it and make it work again because the WR400 has the actuation linkage on the outside and a little dirt occasionally gets in there when driving through mud. It's not rocket science and you notice it when you accept the throttle.
    So enough written, hope to have helped you a little with your decision.

    only for models 98 and 99 with external accelerator pump actuation rod.
    I also did it twice a year. takes 10 minutes.

  • nope there wasn't, there were clutch problems

    yet there was. mainly with the yz426.

    What should be noted, however, is that you should take a closer look at this faked baffle plate in the carburetor

    this is not a baffle plate but the slide plate. and that should be checked for cracks at every keihin FCR.
    many a motor has already inhaled parts of it and then dies.
