Rebuilding my 250r and was wondering what fuel to oil Ratio, and brands of oil are the "best"?
Is there a recommended break in Ratio, if any?

 

[BLACKeR]

i run amsoil dominator 40:1. any of the name brand quality synthetics are fine. some swear by 32:1 i dont see any real difference as long as your within the manufacturers recommended ratio. i run 40:1 because 40:1 mixed with 5 gallons of gas is half a quart. this way i dont have quarts sitting around with 3 oz in them.

Thanks!

I always run 32:1, but I agree with Blacker, 40:1 isn't much different. I also ran Amsoil, but also started to run Blue Marble, which is expensive but awesome. I haven't tested a lot with it, but from what little bit I did, I feel it is better than Amsoil.

I run the same as BLACKeR. Been doing ok for me.

I was running same as Blacker. I switched to Ams Oil interceptor. Same ratio still. It is a little cheaper and seams to be working just as well.

for over 9 years . . been running 32-1 ratio with a semi synthetic oil...& have never hurt a motor yet !

actually I used to have a link to a website that explains (scientifically )why 32-1 is the best for long life & lubrication etc for every 2 stroke over 200cc's ...I find it again I will post it

didn't it say they did dyno run and produced more horespower with 32:1 or something close to that than any other ratio.

Yeah. I think I remember reading that. Maybe that was 2Rs link I was reading.

Yeah ,...
I think that is 1 of many highlights ...& lubrication for the normal volumes of the motors being talked about in the article ..all over 200cc's

A friend introduced me to opti-2 and i use that at 100:1 and my bike has never ran better. my friend swears by it he's had less problems since using it and cylinder stays in better condition.
