When engine is off, headlight and rear light dims when front or rear brake is applied. 3. When engine is on idle, headlight and rear light dims every ~2...

    Engine running hot

    Hey mate, have you checked your spark plug color?. If it runs lean, temperature can go up. I had a similar issue on my max and after carb clean-tune, temp came back to normal.

    Fork springs and oil amount

    Hello everyone, I had to change fork seals on my '97 VMax and noticed that fork springs are quite longer then stock ones. Basically there is no tube between spring and top screw. When screw is taken off, spring gets out like 5cm out of the fork tube. I guess that previous owner replaced stocks...

    Vmax on 3 out of 4

    Strange, original Yamaha needles arrived and they look exactly the same but I was not able to screw them in. Sounds like thread is different but when I put old and new needle together, threads align perfectly. Anyway, I used new o-ring and spring on the old needle and still engine does not...

    Vmax on 3 out of 4

    So I did another shotgun on all carbs and now 4th cylinder works fine. Engine stumbles when needle jet is closed. Front right cylinder still does not react on closing needle jet and bangs come from right exhaust. It is also not heating up like other cylinders. Will try another cleaning round...

    Vmax on 3 out of 4

    Stripped carbs completely, cleaned them with carb cleaner and air compressor and nothing seems to be clogged. Then I synced them and all 4 are bit above 200mm hg. Engine sounds better but still there is no difference if I unplug the coil signal cable (yellow connector) or connect it. Replaced...

    Vmax on 3 out of 4

    Hello everyone, few months ago I had my valve shims checked, replaced intake rubbers and fuel filter on my 1997 Vmax. All worked well for like 150km and then I could feel the loss of power. It behaved like there is not enough fuel, stumbling at 3000-4000rpm. Right-back cylinder now does not...

    Oil in Coolant

    Hey guys, I have the same problem on my 1996 vmax, as you can see in attached image. It is now 1500km since coolant was changed and it feels quite oily. I did not notice oil level drop. Water pump was never touched but this crap never showed up before. Can you please explain what is "oil...

    22L/100km fuel consumption on the racetrack!!!

    Oh man! :) I usually ride vmax like a girl but when we got on the track it was now or never :) Brno track has a few downhill straights with hard corners at the end, and we all know that vmax is not the fan of braking and cornering so it was a bit scary :) We were riding on Saturday evening and...

    22L/100km fuel consumption on the racetrack!!!

    Hi guys, few weeks ago we went to MotoGP in Brno Czech Republic and we had an opportunity to ride on the track. In the camp right before the ride I topped my fuel tank. For 3 laps on the track (one lap is 5km) and 5km of highway ride to the first gas station, my Vmax burned 4.5 L of fuel. That...

    Rattle noise on idle

    Problem was in fuel mixture and too low number of revs in idle. For now I cannot hear this noise. Will see what happens.
