    It is simply the way this oil was engineered. It is designed to run at 100-1. Smokeless, odorless, so I use in both my 2 stroke bikes and my chainsaws. I like it a lot.

    For me the Opti-2 doesn't smoke,doesn't make a mess on the bike, doesn't foul plugs and the engine runs fine. What is not to like?

    Also the local construction equipment rental yard was one of the long term testers of it and did not have a single oil related engine failure in ten years. Opti-2 headquarters is here.

    Scared to post on here casue noone has in awhile, but I just put opti 2 in my bike today. Have only gone 11mi hoping to notice the diff soon but i lost some power and top speed. I was running 32:1 maxima castor 927 and it was just starting to really run good after air filter and porting intake and exhaust. I gonna keep runnig opti tho cause everyone says it gets better with more miles.So no one has ever needed to mess with the jets or no? I think it is running rich now?

    It's logical that it would be running fuel rich now. I'll bet you also had better ring seal with your 32:1 mix as well.

    I would like to try Opti-2, but there are no distributors in my area. I have been running Wal*mart 2-cycle oil at 40:1 in all my stuff with no problems, but am wondering if I'm missing out on something?

    520,

    The fuel viscosity at 100-1 is thinner than 32-1. Thinner viscosity fuel will flow easier and faster through a given size jet. So it will run richer at 100-1 than it did at 32-1. The stock jet is .70mm. Order from Sick Bike Parts a .68mm and a .66mm jet. Try the 68 first and it should run better. Then try the 66. It may be even better yet. If it sags at fill throttle it is a little bit lean. If it stutters at light load part throttle it is rich. I run a 66 in mine and it is best for me. Also put the needle clip in the top groove of the needle. I run Opti-2 at 100-1 and my engine seems to love it.

    Here's an anecdote from my friend and multi time ISDT medalist Hemut Classen:

    At my first ISDT in 1962,OPTIMOL approached our team and offered us full gas
    and oil and money sponsorship,....
    If we would use there mix.
    At that time a racing mix for 2 strokers would be 20-1 with Castrol.
    Optimol mixed then allready 50-1.
    We where shocked but the overall offer was just to good so we went for it
    All four of our team made it through the ISDT
    With 1 Gold,2 Silver and one bronze.
    In 19 71 I was approached by TORVAN distributing to test for him this "new"
    oil coming from Germany,but now
    We had to mix it 100-1.OPTI had followed me all the way to Canada
    -:))))))))))------->>>>>>>
    I tested the OPTI lubes on my Zuendapps and Hercules and never looked back.
    You will find the oil at many small engine shops who selling chainsaws..
    (all running 100-1.)
    SACHS racing oil, Maico racing oil,and several other companies ,...guess
    what oil is behind there names???lol....
    Castrol bought GERMAN OPTIMOL WERKE some years ago to get the formula.
    Result? Castrol Syntex...)
    Mixing gas and oil has nothing to do with fine tuning your engine.
    I have some 100 or more customers who using OPTI 2 in there engines for year
    mixing 100-1.
    And our 4 stroke bangers using OPTI 4.
    BTW.OPTI W 30 oil is great tranny oil.

    I didnt think it was helping at all till i started to run the bike at wot all the time for the last couple of days. I am fighting with the tunning now i had the bike running perfect and now i cnt senn to get it right. It is really smooth in all positions to wot. At wot it runs fine till about 27mph then it starts vibrating tons and 4 strokin. once it hits about 31 to 32 it smooths out again and just scream but cnt tell if it 4 strokin any more if it is i cnt here it. I already went down to .68 jet any help would be nice

    Bumping classic thread!

    Just one question..do you clean the old oil out of the crankcase when changing over, or just go for it?

    Also, inb4post500, and yes, I read the whole thread yesterday, and no-one said anything about cleaning out the old stuff, so I guess you dont bother, but I just wanted to check.

    there's really nothing to clean. the oil burns with the gas, probably leaves some residue but it's not like you've got an oil pan full of crap.

    running a tank fulla opt-2 would just burn all the old stuff out.

    Toxic,

    Try a 66 jet. That is what I am running. Needle clip in the top groove.
