    Wow, what a thread.
    Read the whole thing today, mainly because I'm building my first motorized bicycle and want to make the motor last... and I'm convinced enough to give Opt 2 the chance from the first start.

    Definitely was a good read, thanks for all the useful information and insight.

    Boy, you just read the whole thing? The Thread That Would Not Die. I believe that means you must have won some kind of prize as the one millionth customer or something like that. A free packet of Opti 2 may arrive in your mailbox any day now. Congratulations. I think this is also an indicator that you may well end up addicted to motor bicycling. Just a heads up in case you want to back out now. You could just pedal away and pretend you never read any of this stuff, but I'm guessing it's already too late. With that, I welcome you to the forum. Your life may never be the same again. I was only going to post one or two times and now here I am over 2,600 posts later. If for each of those posts I had instead collected one pop bottle I would now be a rich person able to buy a number of bike motor kits.

    Yea, it took me awhile but I did it. Slow day at work, so I kept the window open and read it in the time I should have been using to get ahead. As for the addiction thing, well lets just say your signature line applys equally to me.

    100:1.. I say.. Do not do it.. Not worth it. It may run better, may.... You will use less oil.. some... You may save a nickle short term .. Still.. I say.. Don't do it.

    I have yet to see anyone whip out beakers and eye droppers and measure to the drop oil fuel mixture. If you do that NASA is hiring,rotfl

    If you are saying that then you and I have not been reading the same thread. So many members here, whose opinion I respect very much, have reported very good results and many many miles of fun. And less oily mess.

    I have kept up with this thread since its start. Any 2-stroke motor I use in the future, on a bike or otherwise, will get Opti-2 @ 100:1 from day one. That choice is heavily influenced by the opinions of respected members concerning Opti-2.

    so... you say it may run better, you will use less oil, and may save a nickel.

    it does all that and more.

    what kind of experience do you have with opti-2 to warn people off?

    i've got 1 bike a year old with over 5k on it that i run 45mph+ all day long, another engine with 2 months on it i rode 75 miles the first day flat out, 35 each way, only stopping for lights. another bike, 4 months old with about 1k on it, and 3 friends bikes, all still on the road, all going strong, all saving nickels, using less oil, and running better than most bikes out there.

    i say... Do it.

    Duane, Duane, Duane...I live just a couple of blocks from you and you've ridden my bikes (with your engines) and you're still not convinced. What am I going to have to do to get you to change your mind? (Just a note to others...Dax has warned me he won't warranty my engines....that was several hundred miles ago and they're still running strong)
    By the way, that friction drive thing I rode today is the cat's meow...You should really consider seeling it on a limited basis. Let's see how it performs after a couple of hundred miles. If my Chinese in frame bikes ran like that...:)

    ARRR, Who here be man enough to join us? Try this new brew? We are Bikers are we NOT? They told US the world was flat, and we would fall off, if we sailed to far. They told us that atoms were a myth,
    and Rush Limbaugh would never be skinny. I will risk a motor. (c)

    The Magic Mechanic here in Orlando is the most "in-demand" mechanic in town. He has a call-in car radio show and is an AMSOIL dealer and advocate.

    He characterized the oil as one that gets inta and unda all the dreck in the engine. It also seems to get into the threads of my head bolts because a tank or so of 100-1 Amsoil 2-stroke oil and now my head bolts on one side are starting to seep tiny bits of oil. No performance issues. the bike runs smoother and better but I gotta find a thin wall socket to tighten it up

    Well heck, i just have to be in on this record setting thread.... read about the first 8 or 9 pages, just till tom had the loss of power... in my way of seeing the inside of an engine without actually looking in there, seems the loss of carbon build up dont fly, it happened too fast...more likely a loss of compressin due to lack of oil...no matter the quality , it still needs enough molecules of oil to fill all the voids bettween the ring and the cylinder wall....and as one other post said the the main and rod bearings as well...if the china engine piston and or cyl. is too hard it may never seat properly and is relying completly on the lubricant for compresion... about 20 years ago i got several truck loads of 460ci ford industrial engines , these were new, straight from ford. .. we ran them on propane in wind machines....the rings were chrome moly and would never seat using the dry fuel.... until we switched to cast iron rings... took a long time to get the ford people to pay up... but eventually their engineers admited the problem and it was settled...took two years...anyway, in my mind its just not enough oil .... probably hard metal in those particular engines , which probably varies alot from chinese production run to chinese production run.... would explain the different results from one engine to the next....

    Well, I though it might be a good time to update. I am currently on my 5 tank of gas mixed with the Opti 2, 100-1.

    The engine always starts within a drive way length, runs strong without smoking and dripping oil out of the muffler. The speedo say I have logged 534miles.

    If this engine was going to fail due to lack of lubrication, I think it would have already happened.cvlt1

    It could be causing more wear than normal on the cylinder wall, very slowly eating the bearings.... etc. But after that long it's probably fine. I'm interested to hear how it's running around mile 2000 or so. That's when a lot of these seem to start having issues.

    Yo Tom I've been working in the small engine shop for the Capitol, we have abour 6-8 Toro 2 cycle mowers with suburu 5 horse engines. These mowers have 1000s of hours on them and were scheduled for salvage at the end of last (09) season. I convinced the management to go for Opti-2 because we wouldn't be out anything. At the last of this mowing season these mowers were running better than some of our new 4 cycles. It looks like the stuff works pretty good. We also use regular gas no alcohol blends. This makes a big difference on all air cooled engines. The 2 cycle engine was not designed on blended fuel mixtures.

    Keep it civil, guys. This isn't an argument thread but just discussion. If you disagree, so be it, but don't attack another member just because his opinion differs from yours.
