I have been using 927 since I have had my 89'er. Its a good freaking oil! At any rate I dug up some stuff on castor and its properties:

Castor oil's high lubricity (reduces friction) is superior to petroleum-based lubricants; for instance, it really clings to metal, especially hot metal, and is used in racing and jet (turbine) engines. In addition, Castor oil is non-toxic and quickly biodegrades; whereas, petroleum-based oils are potential health hazards, and take a very long time to biodegrade, thus can damage the environment when concentrated [18].
http://en.wikipedia.org/wiki/Castor_oil

Castor oil has other unique properties. It is highly polar and has a great affinity for metal surfaces. It has a flash point of only 445 degrees F, but its fire point is about 840 degrees F! This is very unusual behavior if you consider that polyalkylene glycols flash at about 350-400 degrees F and have a fire point of only about 550 degrees F, or slightly higher. Nearly all of the common synthetics that we use burn in the combustion chamber if you get off too lean. Castor oil does not, because it is busily forming more and more complex polymers as the temperature goes up. Most synthetics boil on the cylinder walls at temperatures slightly above their flash point. The same activity can take place in the wrist pin area, depending on engine design.



Synthetics also have another interesting feature - they would like to return to the materials from which they were made, usually things like ethylene oxide, complex alcohols, or other less suitable lubricants. This happens very rapidly when a critical temperature is reached. We call this phenomena "unzippering" for obvious reasons. So, you have a choice. Run the engine too lean and it gets too hot. The synthetic burns or simply vaporizes, but castor oil decomposes into a soft varnish and a series of ester groups that still have powerful lubricity. Good reason for a mix of the two lubricants!

So basically, the hotter the metal, the better castor works!

I am going to start using this in my no2 bikes the Klotz benoil stuff is ok but I had some separate in the c-12 again

Ya it be the good stuff, I use 927 for MX and trail riding, 747 for flat out road racing.

BTW with castor based fual mix, Glen told me it's best to alway shake your bike good before each ride. On top of that I always drain my carb.

BLENDZALL FOR LIFE!!!!!!!!!!!!!

I get it from Stockton Honda Yamaha. I usually buy a case of it at a time.
I buy the gallons there is 4 to a case. lots of suppliers carry Blendzall.
I love the stuff I have been running it over 30years not one problem.
some peeps will say it builds carbon on top of the piston that just
means more compression........... silly kids!!!!

Thanks Ill be running this oild this weekend , Paul have you ever had this oil seporate from the race gas?

I have not.......... it "Blendz-All"

anyone used this oil r30 made by castrol

I highly reccomend the KLOTZ super techniplate. 80% syn 20% castor bean. great product, good price still has some of that chubyy one castor smell

i bought 2 cases of it on ebay

my engine builder/mechanic uses it in his TRX310r

I have never had any lubricity or seperation issues with 927 and will run it in any 2 stroke bike i get.. Its good stuff and smells ohhh so sweeet first thing in the morning.. a little ping ping ping with race gas and castor to wake ya up ... DAMMIT i wanna go riding now.
