My dumb buddy who just traded his new 08 rancher 420 for a 86 Honda 250r because it was faster, yes hes a little slow. He doesn't know any thing about 2 strokes whats the oil to fuel ratio for this bad boy, prolly be running amsoil, klotz, or red line. A few other questions, wheres the Vin on this bike. There is a problem in my town with stolen bike lately, just want to be safe.

20 : 1 jetted properly is the best bet, just like it says in the manual. A properly jetted bike at 20:1 will have no oil spooge and very little smoke.
32:1 is for the newer 2 strokes with a powervalve. This thread will create alot of debate

lol yeah it will, lol 20:1 is for oil technology from 86. oil has changed alot since then.

I agree.
32:1...I use Torco GP-7. I hear great things about red line oil.

No it hasn't..Maxima SuperM, Belray MC1, Yamalube, Goldenspectro, ect. All oils from the 80's and earlier and are the same formula then as now. I keep hearing those kinds of statements and with thinking like that timeframe we should all be running our bikes at 100:1 in 2015?! Nope! If the bike is jetted properly 20:1 (which a stock Honda 250R is) will give more power and engine compenents will last longer. Just run what the manufacturer says and you'll be fine.

with the new synthetic oils of today i have seen many people run 50:1 in their 250Rs, so dont think people could have gotten away with that in the late 80s. maybe not all oils but some have definitely changed.
either way, 20:1 or 32:1 the differences noticed will probably be minuet.

Klotz Super Techniplate. 32:1. Nuff said.

Klotz is really really good, used to be my favorite but I have found Maxima Formula K2 to be even better. Burns cleaner and throttle response is even crisper. ;) Told ya this thread would create alot of pissing !

Only oil on that list I'd use is the maxima. And that'd only be if I couldn't find another.

I ran Amsoil HP Injector at 40:1 in my 250R trike for 3 years and now I run Honda HP2 at 40:1 in my TRX. No problems at all.

hey dude, klotz super techniplate has the highest dyno hp, and is rated to 9000rpm +. And no, 2 stroke oil ingredients have changed over the course of 30+ years. 32:1 has been proven to have the best benefits at any rpm. I have owned 4 2 strokes in course from 2007 and now, and I can say the 32:1 is a safe spot.

the funny thing is that this question is about as old as two stroke engins... whats better in 1 persons app. is diff. from anothers same as ford vs chevy or JD vs IH i just bought a 85 250r & havent had something i had to mix for a long time am i understanding that i should run 20:1 ratio?

Facts...the best power can be found at a ratio of 18:1 on a stock motor. However, this is with the assumption that you will be at full throttle 100% of the time. Realistically you will not.

Get a decent 2 stroke oil...run it at anything from 20-50:1 and you'll be fine. Personally I wouldn't run less than 40:1 in anything. and 32:1 is more to my tastes.

Hell I run 70-1 in the fourstrokes

i have found myself adding a dab of 2 stroke oil in my 110s gas just for ghits and shiggles. no problems at all, i dont see how it could effect anything negatively in small amounts lol.

I think the 20:1 from Honda was a very safe conservative ratio, and they have no clue of the quality of fuel and oil you are gonna dump in it. Ill also believe that most 2 stroke oils, especially synthetic oils have come along way in 25-30 years. I run my R at 36:1. Bel Ray H1R great response and power, dosent smoke bad. Dosent foul plugs The directions say 32:1 for 125cc and smaller and 40:1 for 250cc and larger. 32:1 seems to smoke alot and get the exhaust tip wet and black. But it runs great. fouls plugs if i let friends ride it that just putt it around. 40:1 ran good also... alot less smoke and no exhaust spooge so i figured smack dab in the middle ive been running 36:1 through winter and summer WITHOUT rejetting. no problems what so ever and its fast all the time. No bogging hesitation etc

Personally id run 20:1 with whatever oils cheapest. Right now in useing Pennzoil (spelling?) in the boats and everything. I ran 32:1 in my dirtbike (1978 yz 125)and the stupid ass thing siezed up so now im at 20:1 with anything bigger than a weedeater.

guys, if 40:1 ratio is considered a safe zone for newer 2 stroke motor's(the yz250 sharing almost identical characteristics as the 85-86 atc250r piston) don't you think 20:1 is a little excessive? and you can't simply blame the ratio squirrel, jetting has everything to do with it. Another thing to consider is that a lot of people run 20:1 ratio to break in there bikes...

Yes i know i think it was a combination of both. But im scared to run anything diff because im only 15 and have like no cash to repare what breaks. And my dad buys the oil for his boat in the 1 gallon jugs so i dont half to pay for it. And also 20:1 because if i can see the oil stains on the end of tailpipe it just assures me that its getting enough oil.
