I ran R30 for a number of years at 50:1 in every two stroke I had. LOTS of carbon build up and stains EVERYTHING it touches orange. (lucky I run KTM'S ) Changed to Maxima 927 and haven't looked back, far less carbon, less smoke, upon pull down nice thick coating on everything. Nothing wrong with R30, but I think Maxima is a better castor oil.

Thanks Guys . does it seperate when not n use and do you have to empty everything between meetings, this motor is fairly warm and the comp is pretty high , been using belray s7 but found it has no give when on the edge , when you get a seize even if you are quick and hear it comming the engine is F$$%^^ed and a rebore is required.
