adam1 Posted September 13, 2015 Report Share Posted September 13, 2015 hi all I have been using this in my 315r with good results and I love the smell... I have just bought a 2011 beta evo 250 which has Been run on putoline TT trials. Is there any benefits to running either 2 stroke oil and if the castrol a747 was the preferred what would I need to do to start using this? Thanks Quote Link to comment Share on other sites More sharing options...

Is there any benefits to running either 2 stroke oil and if the castrol a747 was the preferred what would I need to do to start using this? Thanks To the best of my memory...Castrol A747 is/was a synthetic based oil with some castor elements (hence the Castrol "R" smell). It was intended for highly stressed 2 stroke road race engines (Yam TZ, Honda RS etc) and was pretty pricey and also had a shelf life, I think. It had a "sister" oil for off-road and less demanding applications that was Castrol A545 that was then renamed something else... John Shirt Snr used to SWEAR by it when he was involved with Yam TY monos..Most good two stroke oils will serve well in trials applications IMO Quote Link to comment Share on other sites More sharing options...
copemech Posted September 14, 2015 Report Share Posted September 14, 2015 The castor oils smell good and all, but tend to gum up badly in the exhaust of a trials bike. Not enough heat in a low stress motor application. Really hard to clean out too, I will add. Quote Link to comment Share on other sites More sharing options...
dadof2 Posted September 14, 2015 Report Share Posted September 14, 2015 Full or semi synthetic best for trials. The castor based "synthetics" like A545 and A747 only have an advantage at the extreme limits of lubrication. At the limit non castor oils thing out and evaporate of meaning no lubrication. At this limit castor oils thicken and char preventing metal to meta contact, or at least trying to Quote Link to comment Share on other sites More sharing options...
