2 cycle oil

[hogmuffin]

I'm new to 2 cycles. i wanna take my new 250R out for a ride tomorrow, and the guy i bought it from gave me some castor 927 racing formula oil and mix it 32:1. Does it matter what type/brand of 2 cycle oil I use? what is the best stuff for my 250R? its pretty much stock its got a 32mm carb, and paul turner pipe. any help would be greatly appreciated!

[atc007]

The short answer is,,oil is oil,, Mix @ 32-40- 1 and you'll be good to go. What IS much more imperative is that you have a Clean,,OILED air filter. Clean carb and fresh oil in the tranny. On a better note,Fabio will be OVERJOYED you started a oil thread!! Enjoy your ride!!

[hogmuffin]

haha thanks a lotfor the info!

I also have a question regarding this.... I hear 32:1 and it says it in the Honda factory manuals as well, but the sticker on my 250R says 20:1..... any reason people are running them leaner now???? I have always mixed mine 20:1 and never had plug issues etc. To add to the original question, I perefer the Honda HP2 synthetic racing oil from the dealership in the blue bottle... but thats just me. Oh... my bottle also says 32:1.... :scratchhead:

[atc300r]

Is your oil Maxima 927.Thats a very good oil.Some of the old timers back in the day say not to mix sythetic oils together .They mite not be compatible.What I do if i have to switch is drain the tank and cab and start with new.I try to run a oil that I can get steadily.Here where I live its Amsoil Dominator I run it at 32-1 with 93 octain gas.

The 20:1 on the tank is from back in the days that they were using motor oil mixed with the gas. With the advancements in oil technology, about any 2 cycle oil mixed at least 40:1 should be good in almost any situation

Good to know, Thanks! :)

Maxima 927 Castor has a stellar reputation and is highly recommended by some of the best 250r builders in the business. I have recently switched to it. I used to run Amsoil Dominator but I discovered when I took my engine apart to do my 350 big bore over the winter that the Dominator oil isn't very good at preventing corrosion. This is not regurgitation of anything I read on the net, but experience from seeing the internals of my own engine with my own eyes as I do all my own engine work other than machining. After much looking around I kept seeing the Maxima 927 Castor recommended over and over again by reputable 250r builders and owners. I cannot yet speak to it's corrosion preventative properties but I can say my R runs great on it with no negative side effects. ESR recommends the Maxima 927 oil at 32:1 with the spec/instruction sheet they send you with their cylinder kit as does the owner/operator of BDT Motorsports. These guys and others have been in the 250r business a long time and know their stuff.

As to what ratio to run it, I run mine at 32:1 as recommended by ESR with my cylinder kit. I have found that 32:1 is the most frequently advised ratio to run with the Maxima oil. You certainly won't hurt it running 20:1, but these engines can be very safely run at 32:1. You could probably run it safely at 50:1 but I like a margin of safety and would be very apprehensive about any sustained high RPM running at that ratio. Why take that chance...

Oh, and it smells really good too, like a nitro powered RC truck ;)

32:1 KLOTZ. Just burned through a tank today on my TRX

[volfan537240]

i run 927 at 32:1 also. i also agree that if youre gonna swap name brand oils, drain the tank of all the old stuff.

[gus]

I tryed running 20 to 1 fouled my plugs every 10 mins I use. Golded spektrum 50:1 ration in my r no problem! !

[just ben]

I am embarrassed to even reply in this thread but I would recommend running your oil at the oil mfg's recommended ratio. oil is not oil as said above. For a conventional oil 32:1 is a good start. for any oil that is bought beyond a gas station,stick to what is says on the bottle. I'm pretty sure they spend a ton on r&d before putting it out for consumption. One oil may provide the most protection and performance at 40:1 while another may be 100:1. If you can figure out how to get online and ask what ratio to run you can read the bottle.(meant in general,too many oil threads)

[hogmuffin]

wow thanks alot everyone for all of the input. i have about 8 ounces of the castor 927 left that came with the trike. im going to mix it up tomorrow 32:1. I am very excited for my first real 250R experience.

Do it, you'll be fine. Enjoy the ride and wear your lid.

[falloutboy]

I've heard that once you run castor oil, it isn't really a good idea to switch to something else, but that's just what I HEARD...

[gus]

Hold on tight that R will blow you away no kidding lol I would now

[muthey]

I can attest to the leaner oil mixes now days, as I was given two chainsaws from the 70's that call for 16:1 and when I mixed that they wouldn't start, but when I went to 32:1 I have had no issues at all. My grandfather who gave me the saws said he started running them at 40:1 here not long ago, but I would rather change plugs more often than be without my saws. I went camping with them this weekend and they were so nice to use to get firewood vs. going out with the truck and gathering it up that I had a pile cut and laid out at the campsite faster than before. Plus no more quick burning drift wood anymore, now its nice thick dried tree rounds that burn hotter and longer. Moral of the story is the oils have changed dramaticly since when they put the ratio mix on there.

I had a lot of fun. that thing definitely has a lot more power than my KLT 160. its hard getting used to the different shift pattern. is there a trick to shifting back into neutral from first? that was my biggest problem

[jb2wheels]

FWIW - I run the Honda synthetic from the blue bottle @ 32:1.

Clean, lube and adjust the clutch cable to be sure you're getting a full pull.

Change the tranny fluid. If it's been a while, fresh and clean and the right weight will help keep the clutch from dragging. It's only 1/2 quart or so and takes all the abuse from the clutch.

Which oil to use in the tranny is a whole different thread ... start with reading the manual.

I run BelRay Gear saver but I think it's a bit too heavy for the job (I can feel the clutch dragging when cold) and will switch to Hond GN4 20/50 this time.

Make sure the clutch is correctly adjusted and that your idle speed is not too high. If that doesn't fix it you likely have some warped steel clutch plates.

[hogmuffin]

the manual says 10w40 in the tranny, but the guy i bought it from used 10w30

[gus]

I use what's recommend by honda I think its 80 weight? Ya but if you can't get in neutral you gotta change that tranny fluid

[xman2rman]

I run Maxima 927 Castor at 32:1, 93 octane and STA-BIL marine formaula to combat the effects of ethanol. I have had a lot of problems with ethanol causing water in my gas. I put the blue sta-bil in everything now and just to be on the safe side, I would never switch my gas tank to the reserve position because if you do have water, you'll be pulling it right off the bottom of the tank. I also run Type F transmission fluid in my 250R gearbox.

Hogmuffin, I would consult Fabiodriven on here. He is the resident oil expert and loves nothing more than to talk shop about oils. Ole Fab's is a second cousin, twice removed, to a Texas Oil Millionaire. He taught him everything he knows about the oil industry right down to how to wear the proper Ten Gallon hat. But what ever you do DO NOT call all oils the same if you talk to him.

His specialty is the molecular bonding agents in 2-stoke oil vs. the viscosity break down of the thrust capacity, along with the rudimentary cohesiveness, combined with semi abrasive vs. semi non-abrasive particles, that make up all 2-stoke oils.

It might sound complicated but he can splain it to you like you were 5 years old because he just loves the damn stuff so much.

Don't forget to ask about the sliprification ratings that NASA engineers use to grade oil.

[bkm]

Don't forget to ask about the sliprification ratings that NASA engineers use to grade oil.You don't even want to go there. Fabio started in on that one day trying to explain it to me. He had to use a visual aid that consisted of a Twister Game Board, bottle of Baby Oil, and three Strippers, before I understood what the hell he was talking about.

Three rippers and a bottle of lube? I might could go for an explanation like that!

Make sure the clutch is correctly adjusted and that your idle speed is not too high. If that doesn't fix it you likely have some warped steel clutch plates.

Also could be grooved clutch basket fingers.....

And for the record the Honda (not Clymer or anything else like that) 250r Service manual lists 10w-40 for the widest temp range. 80w may be good for racing when you are beating the turds out of the clutch, but might be a little thick IMHO for normal riding. Just be sure and get oil that states "wet clutch safe" or an oil designed for motorcycles.

I use simple Valvoline 10w-40 ATV Oil and have had great results.

[johnny's X]

Todays oil...... 50:1 bike will run great and and no more carrying a plug with you. Hell i run my little zinger 50:1

[4x4van]

As a few have already stated, run a good quality oil at the oil manufacturer's recommended ratio. I've run Golden Spectro at 53:1 for 35 years in every 2-stroke I've ever owned, motorcycles, ATVs (even my weed eater gets the good stuff!), and that includes 6 years of racing professionally in the deserts of SoCal back in the late 70s/early 80s. IMO, you can't get better oil.

Keep in mind that oil takes up "space" in your gas/oil mix, which means that if you run a richer premix ratio, it will lean out your carb jetting, and vice versa. See my post here: http://www.3wheelerworld.com/showthread.php/53212-All-About-2-stroke-Oil-Ratios.-Interesting-find/page2 for a detailed explanation.

[Gripit'n'ripit]

I run 50:1 like Johnny. I go richer when I'm breaking in a new piston. Just AMS oil. Gone through a few 250r's and several dirt bikes, no issues yet.

[atc300r]

Back in the 80s my uncle had a 82,two 83s and a 85 250r and he ran them at 84-1 with amsoil.He never had and issue with any of them.The trikes where ridden every weekend all year.There was a guy that had a snowmobile shop back then and he to my brother and i the he ran a Can-Am dirtbike at 150-1 with amsoil.Im not 100% sure on that one.But he could afford to expierment with different ratios.

[El Camexican]

I got my second snowmobile (cheap) from a guy who used no oil whatsoever. Eskimo guy from up North, didn't understand the whole ratio concept. He said it ran great till just about when it seized solid while he was chasing down a walrus. After the rebuild I used ESSO 2 Stroke Oil at 40:1 and the rings lasted until I sold it.

[badass350x]

The only oil I use is Amsoil Dominator at 40:1 burns clean an never a problem, very good oil!

[johnnytri-z]

i run the dominator too 50:1. and i always add a pinch of marvel mystery oil in everything i own 2 or 4 stroke.1 oz per 5 gal.

I've always preached you can't go wrong with products that say "Mystery" on the label. I look for it whenever I'm grocery shopping. Seriously, what exactly is that stuff supposed to do?
