read this to understand why Opti-2 keeps coming up...
Been using the opti oil for 8 months with no apparent problems what so ever. The usual bragging by the others on this site got to me, I was really sold on it when Retmachinist pm me that it was the real thing. All you guys that are skeptical, I say whatever, the only catch is that it's not compatible with ethanol gas. That's not a suggestion it's a fact.
Sorry Glen I have to disagree with you on the ethanol issue. Colorado has had 10% ethanol for years and that's all you can get here. All my engines, bikes, cars, lawnmowers and trimmers are run with the ethanol based fuel. My bikes thrive on Opti-2 and Ethanol. Not just my opinion, it's a fact, sir.
in the link that "momentummotorgroup" posted, the last line stands out "...The harder the engine is run, the more effective the lubricant becomes..."
i totally believe in that statement. like i've been saying, i run it 100:1 from day one at full throttle for extended periods of time, and it just works. my first motor was broken in the conventional way, 24, then 32:1 valvoline from autozone, and it took a month of hard riding before it finally broke in, and that motor was never as strong as my others.
besides the ride around the block, i rode my latest motor 35 miles at WOT with almost no stops, not even for lights (Newport Beach to Signal Hill on PCH, miles between lights,) then hung out all day, then rode back. temps were 85 degrees, and the return trip was against the wind the whole way.
the motor loved it, i loved it, the environment loved it.
bottom line is, you'll never know it works until you try it, and if you don't try it, then you have no room to debate it. how can you pass judgement without making an actual comparison yourself?
the real bottom line is, if Opti2 was beer, i'd drink it.
I think he may mean E-85 because almost all gas sold nowadays has at least 10% ethanol.
The opti2 oil that was shipped to me came with the warning about E-85 (thanks Kevlarr your right). I can remember you posting how your engine bogged down with no power,Tom, so something must of happened since. You even told me about it on a telephone conversation a while back. Maybe it was the Chris Hill engine I can't remember but you said it caused the engine to barely run it was running slower than ever. You have either a short memory or you used a richer mix than the 100 to 1. Correct me if I'm wrong but I clearly remember having that phone conversation, you said you barely made it home with your bike.
Pretty sure that was an odd case of a well-used engine that was swapped over to Opti after a lot of usage with regular oil & mix ratios... and it was a bit of a fluke that no one could quite explain (dislodged carbon buildup reducing worn ring compression mebbe)? You'll ofc hafta talk to Tom about it as I don't really remember either *shrug* but as I recall it was also the only mention of any problems experienced, he's got more than one engine heh
Glen I believe you missed the point; that being that I have 4 other 2 stroke engines that all perform perfectly on Opti-2 mixed with 10% ethanol. Yes, you are correct about the Chris Hill engine. It did poorly and to date we can only guess as to why. The best opinion I've seen has to do with the high milage engine initially being run on standard 2 stroke oil and the difference in the way the rings seated (if they ever did correctly). My opinion still stands, that when used as directed by the manufacturer from break in, Opti-2 is a superior lubricant to standard 2 stroke oil mixed to 32:1, more or less.
I'm not up on what ethanol % is available, or mandated in other parts of the country and there is a possibility that Opti might not do as well with a higher alcohol content. I'm not aware of any reports of this and can only tell you what experience I've had with the Colorado blend.
As for short term memory loss; at my age...that's not unusual.
For any folks that switched post break in to opti 2, did you have to make any carb adjustments? I'm on a 66 skyhawk with the speed carb, third gallon of gas and just switched to 24:1 after 20:1 using the maxima oil. Thinkin about going to opti 2 after the maxima is gone.
I'm new here, still learning about these MBs and haven't bought a kit yet, certainly don't know much about them, but I thought I would chime in with my $0.02
I flew 2-stroke ultralight aircraft for years. 500cc Rotax twin cylinder 50 HP at about 6000-6500 rpm. I and many others used Amsoil mixed at 100:1 The engines ran cleaner, better, and I knew on none that seized. Rings wouldn't stick like with regular mix ratios. Gas is also a better coolant than oil. Much more critical when your as_ is on a sling a thousand or more feet in the air! I know there is probably a world of difference in these 2-stroke engines, but the finer ratios had a lot of advantages.
Another biggy was to use the premix right away - not let it sit around for more than a week or so. I poured a lot of 100:1 premix into my truck that got a little "old", never had a problem there either.
You will find several ultralight flyers here that share your opinions. Welcome to the forum and hope you enjoy the ride, (flight)
does anyone know where I can buy opti-2?
I live in Canada
call them and ask. they're real helpful.
yep. they called me back within hours of emailing them, and if you have Ace Hardware up there, they'll have it as it's stocked in that entire chain of stores.
thanks guys i will call them tomorrow
i am new to motor bicycling and have just put together a 40cc china on a smaller norco frame.. it barely fits in the V, but I believe having smaller wheels would make the bike go faster? if i am wrong please correct me
mathematically, a smaller wheel will accelerate faster, but will be slower than a larger wheel at max rpms.
like, a 24" will beat a 26" off the line, but the 26'er will catch up and pass you.
like i said, though, "mathematically."
i've got a 24" that hasn't been beat yet.
thanks for the info, i am finding this site to be VERY useful
i am wondering though, i think I am getting less fuel mileage than I should be.. I am going to buy a bike computer tomorrow though, so I will be able to track my mileage.
any recommendations on bike computers? in the 20 - 30 dollar range
Welcome to forum. I had good luck with the cheap bells at walmart. They have a Schwinn there as well thats prolly better.
I just purchased synthetic from Wally World, made by poulan. 40 to 1 mix cost $6 for a small jug. It is a full synthetic oil, I did notice they had a synthetic blend oil for about $3 a jug. They had it over in the garden center near all the chainsaws and gas tools, No synthetic was in the auto dept just your cheap 2 stroke oils. They did have a gallon jug of full synthetic in auto parts for $26 but it was for outboards. My 2 cents.
Thanks for the advice.. right now I am running motomaster formula premium 2 stroke motorcycle oil. I have noticed a lot of black crud being spat out all over the bottom of the bike, occasionally spitting onto my legs as well.. is this normal, or can I find a way to prevent this? I don't mind it much right now because it is summer, but when it gets cooler I do not want to have this all over my pants and shoes when going to school..
