Ok I have a 1986 Lt250r with a fatty pipe and an answer silencer. What is the best oil to use it the gas mixure and what octane gas do you use? What about the mix ratio?
THANK YOU

 

91 octane
I like maxima 927
32:1

 

I use Klotz Benol at a 32:1 ratio with race gas.

 

OK guys thanks for the help. I'll probably go with maxma since othere people told me this is good. I'll also use 91 octane.
Thanks again

 

I like Maxima Castor 927. I would recomend the highest octane pump gas you can get( BP 93, Sunoco 94, etc...) race gas(110-112 octane) is very expensive and not required for a stock engine.
I run a 50/50 mix of Turbo Blue race gas/Sunoco 94 at a 32:1 fuel/oil ratio.

If i run straight 94 octane it overheats and has less power: If I run straight race gas it runs the same as 50/50 mixed.
In the winter I use K2 or SuperM cause you can't use 927 under 35F and I live in NE Ohio with cold winters.
I have also used Yamalube 2R and like it.

hope this helps you.

 

AMSOIL at 20:1 with 93 octane

 

needaR
20:1
Your just wasting oil

 

everybody tells me that.i would like to switch but i havent fouled a plug yet,my engine hardly had any gunk in it when it was rebuilt,it dosnt smoke, and my jetting is perfect.i dont want to mess with guessing the jets to buy.how off will it be if i go from 20:1 to 32:1?

 

My suggestion is try running 32:1. Mix up a small batch and run it. Chances are, your jetting wont have to change much, and your quad may even run better since it gets to burn more fuel than oil.

 

i run 92 octane with amsoil synthentic at about 28:1
