What mixture ratio
« on: August 27, 2013, 03:50:58 pm »
So after being schooled on the correct mixture for my 'Zilla,  --> I'm curious what y'all are running in your 250s.

Same here. They are 2 stroke engines. They are supposed to smoke.

Whatever they came with. Both of them run stock air box with an FMF. One is getting the FMF changed for a stocker. What jets should I be running?

They smoke less ( a little) after you get them all warmed up and reved through the gears to "clean it out" If you are out for a family ride you dont need as much oil.  But if your wide open 6,8,10 seconds you need more. Impractical to switch back and forth and can affect jetting as well so I usually run 32:1 for most of my riding and yes it will smoke but  thats fine.  If i am going to be hammering it hard wide at the dunes i will go 24:1.   IF you get you a good castor bean oil and stand behind the exhaust while it idles a while you can close your eyes the next day and think your riding again by the smell all over your clothes.  My wife says I stink,,  I just call it    "MY 2 -Stroke MUSK"

 With no power valve to gum up you can mix it a little on the heavier side with no worries. I mix this one at about 30:1 sometimes it gets a tad more oil. 4 oz in a gallon jug and plenty of room to mix it up. It is probably 28:1. Man you have a couple of fun bikes!

32/1 with 110 renegade and 927, 500s and 250s. If you don't know, Renegade is what used to be Torco fuels. Sunoco is the best though.

I run Dominator 40:1 with AVGAS.  500 Fanatic built my engines.  He recommends Dominator at 50:1.  I just feel better with a little more oil.

Bell Ray MC1 at 50:1.  Crazy?  Maybe, but no problems in 25 years.
1985 LT250R stock, 1987 LT500R, and 1986 LT250R purchased in boxes, soon to be project.  Those plus a John Deere 440 Liquifire sled.
