Oil change intervule for non racer??

[150 Fuelie]

I see that Yamaha recommends changing the oil every race, but what about for us non racers? Also, what brand and weight do you guys recommend? I'm a big synthetic fan and run amsoil in all my engines. amsoil makes a bike oil in both 10w-40 and 20w-50.

[FOX426]

There are hundreds of threads on this. The avg. for non racers or high revers seems to be about 12 to 15 hours.

[150 Fuelie]

Thanks, for me that's about once a year.

Why so often, Is the engine that hard on the oil? With the quality of oils these days I don't understand. Today's oils don't break down like just a few years ago. Contamination on the other hand is another story.

I use Amsoil 10w40 motorcycle specific full synthetic and I change at about 10hrs each time. Sometimes a little less...sometimes more. I have an hour meter on my bike and that adds up to about 3 good trips to the track.

Filter every time Wyatt?

[big t]

I do mine after 3 rides. I use Yamalube 4 and bought a stainless steel filter. I clean the filter every oil change. Paid $40 for the ss filter but the oem filters were $13. The ss filter doesn't take long to pay for itself.

It's not a matter of the oil breaking down. It needs to be changed often because of contaminates from the clutches.

Does the filter media catch the contaminents?

[Satch0922]

No. And for the most part all the filter does catch are chunks of metal etc.

I never had an hour meter on my 426 but have one now on my YZ250. Let me tell you...10-15 hours on one oil change on these thumpers is pushing it. REAL ride time for me averages less than and hour and a half each time at the track. I used to changed the oil in my 426 every other ride/race and change the filter every other oil change. So based on my hour meter your talking 3 hours of ride time. Doesn't sound like much but everytime I changed the oil it was nasty and ready to come out.

BTW....my 426 worked flawlessly and never had any cam/valve or tranny problems. I had it for almost 3 years.

I have the Scott's stainless filter and I clean it with every change.

From the clutch and other areas. But Texan is correct; you change it often because it's contaminated, not because it's broken down. Very important to change frequently.

[Guest BrandonV]

I probably average about 3 hrs on an oil change unless I'm out for an entire weekend.

That may seem a bit extreme to some, but the cost of oil is cheap relative to the cost of a major rebuild.

[Jeremiah]

Oil changes are important, but make sure you clean your airfilter after each ride!

[Ga426owner]

On my 450, I change oil after every race and/or every 3 rides for practice - avg 3-4.5 hrs.

Standard paper filters replace every other ride or complete clean of my SS Scotts filter each oil change.

426 brass filters I would clean and reuse multiple times -

Oil is up to you - I stocked up on Mobile 1 red cap 15 -50..........

I had been using a synthetic blend, but switched to the AmsOil 10-40 and noticed a bit smoother clutch feel when it engaged. no slipping. I change it every few rides, when I have time. Maybe 2 rides, maybe 4.
