Hi

What do you think about this check valve ?

Thanks

It seems like not a good place to try to save money. I would use the ones others here have used and recommend.

You could try them out...and see if they work??? And if they don't

38€ in france for 1 check valve YAMAHA...

Les clapets de la pompe à huile fuient ?

[rammstein86]

On verra au redémarrage mais vu les risques que ca merde un jour, je préfère mettre des clapets sur la ligne de graissage.

C'est ceinture et bretelle

[phildu31]

C'est facile à voir : il suffit de mettre de l'huile dans le réservoir d'huile et débrancher les durits coté pipes d'admission.
Pas besoin d'attendre le redémarrage et inutile de charcuter les durits si les clapets ne fuient pas.

One question for the check valve :

You put them with the check valve on the oil pump ? It's double check valve ?

And you put them on the hose with the arrow on the normal way of the lubrification (from pump to intake) ?

[tacky1]

Yes and yes, The double check valves doesn't affect the pump..

Hi

I have one question.

I will restart my rd500. But before i see the oil tank have any oil.

Before starting, i want to be sure the oil is not in the engine. I don't want break thé engine at the first start

How Can i be sure ? The kickstarter don't block and the compression is normal.

Thanks

I am unsure what your question is. I put up a first start up video in 2015 where I ran premix and hooked up clear oil lines to ensure the oil pump was pumping Yamalube. A little bit after five minutes in the video you can see the result.

Thanks but it's not my question.

My question si : for the restart After 20 years of non running, the oil tank is empty. I want to know if the old oil is not in the engine, risk to brocke thé engine at restart.

If i unplug the sparck plug, and make some kickstarter, i Can see that ?
