Beta Evo 300 4T oil quantity.

Recommended Posts

Just swapped my Montesa 4RT for a Beta 300 4 T.

So a bit new to this model having only had 2stroke Betas before.

I followed the downloaded manuals advice re oil and filter change, but on putting the prescribed 900 MLS back in , the oil  window is full , as opposed to half full as the manual suggests. I accept there will be a residual value of oil left in the sump after draining but I don't want to cause damage by over filling, anyone experienced the same or has advice on filling.

Many thanks guys.

I did the mistaken following the manual and 900 ml is way too much

Im around 700ml.I suggest pour 600ml in and then ad slowly till you hit bottom of the window.Start the bike and warm it up and let it sit after shut of for couple minutes and then fill to half window

hope this help

 Also, did you remove the two bottom screen filters? It is a pain, but at least 75 cc more oil.

Thanks lineaway, I did, going to drain it again and fill using the window as a fill point rather than specific quantity.

Have drained it all again .

Opened both screen filters and cleaned.

Changed oil filter then filled to half window. Ran her till warm and topped up to half window.

It actually took just under 700cc.

So no idea why Beta say 900cc in the manual , as it's way to much.

 900 cc for a complete rebuild from dry would be my guess. Just like forks, it is better to go by the level.
