August 7, 20179 yr 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.
August 8, 20179 yr 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
August 8, 20179 yr Also, did you remove the two bottom screen filters? It is a pain, but at least 75 cc more oil.
August 8, 20179 yr Author Thanks lineaway, I did, going to drain it again and fill using the window as a fill point rather than specific quantity.
August 15, 20179 yr Author 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.
August 16, 20179 yr 900 cc for a complete rebuild from dry would be my guess. Just like forks, it is better to go by the level.
