As mentioned many times, check the ground on old bikes :)

Hello everyone, here is the situation I have on my Vmax: 1. When engine is off, headlight and rear light dims when turn signals are lighted 2. 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...

Forgot to write, spring length is 62.7 cm.

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...

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...

New needles will arrive tmrw. Will write what happens.

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...

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...

Ah crap, wrong forum :(

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...

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...

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...

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...

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

Hi guys, when bike is cold or bit warm I can hear rattling noise on idle when clutch lever is not pulled in. When I pull clutch lever, noise goes off. Changed oil just to be sure but noise is still there. It happens on Vmax 1200 1996. Any reason to be concerned?

Re: Vmax 1200 - Engine teperature Hi Wayne, will I be able to assemble coolant system without thermostat? How to check coolant flow? When it was 230 on device temperature arrow was close to red. Vlada

Hi guys, few days ago my vmax '97 started to heat up more quickly and during the ride temp arrow went between 1/2 and red zone. It was around 12deg C (50F) outside and I could feel the heat from the engine. Before, it was around 1/3 position when I am on open road (even if it is 35deg C...

Just to add that I've installed COPs and vmax became a rocket. Thank you Blaxmax. Vlada

Synced all 4 carbs and engine work nicely now. :):):) So it seems that only stubborn dirt in carbs was the problem. Uhh finally. Thank you guys for all the help and ideas. Can you tell me what is the procedure now? Clean plugs and let engine run on idle for 10-20 minutes and check how plugs...

Hi guys, I did another shotgun cleaning and this time used bit more air pressure and now all 4 cylinders start :) Engine works bit rough and I noticed few things: 1. cylinder that did not work has lower temperature then other 3 2. I've took out air filter housing and checked how membrane...
