Iwas wondering if 32:1 is a good ratio to run with 91 octane and Castor 927 oil. My 86 250r is pretty stock except for k&n, PSI pipe and cr250 head gasket. Will leaning out the ratio cause increased power? what is the leanest that is safe for the quad? What is the best oil to use? thanks

 

I go by what the manufacturer of the oil suggests. I use amsoil and run 50:1.

 

One pint of 927 to five gal. of gas.

Get your K&N out. Use a UNI or stock you will have alot longer motor life.
