    my kit 80cc came in friday. installing on a mid 80's BCA. picked it from the trash, lol! cherry mtn bike tho. the chain tensioner stressed me some, wrong angle and not sturdy. I've decided to modify it first thing tomorrow. that an add fuel an I'm off. I hope!! this may be dumb but, I really need to know if there is crank case oil in this thing? I know cars pretty well but not 2 cycle engines. can someone tell me? no plugs, nothing in the manual.. I don't wanna burn it yet...trk

    2 strokes burn pre-mix fuel. Oil mixed with the gas. This oil content is what lubricates the bearings in the crankcase. They do not have any other lubrication.
    If you are talking about a motorcycle, the gearbox does have gear oil in it. It is in a seprate housing from the engine, contained inside the same engine casting.

    Better that then overlooking something that may have been important ;)

    thanks guys.
    I got about a 20 minute ride and got home just before the rain started, WOW! that was fun! kinda ruff up to about 15mph. then it smoothes out nice. no exhaust smoke. should be lotsa smoke with the 16-1 mix.

    No smoke? What kind of 2 stroke oil are you using, smokeless synthetic, or petroleum?

    I didn't notice any smoke while I was riding with the Wally World 2 cycle oil I used for break in just a little when I was idling. Just switched to Opti-2 today, ran an entire tank through and now she doesn't smoke at all. Funny thing is I thought I was out of gas WAY before I actually did run out, was so used to seeing blue in the fuel line that when I looked down and saw it was clear I freaked a little because I was 20 miles from home. rotfl

    I'm using walmart Poulan synthetic oil. I didn't realize it was low smoke. do these motors usually chatter like they're comming apart?

    That depends on what you call chatter.
    They do make alot of noise, especially when brand new. The parts need time to bed into each other.
    The "break in" period. After that they will quiet down a bit, but still make alot of noises.

    I've got just over 40 miles on the bike now. and it runs great under a load accelerating and cruising at about 20 mph. but slowly accelerating or trying to ride slower it runs ruff. should I be trying to tweak the carb yet? or better to get thru breakin first? I don't want to go fast all the time. any advice would be apreciated. THANKS in advance

    It seems like all of the cheap 2 strokes run like carp untill they are finally broken in.
    You can fiddle with the carb, but be dam skippy sure it is not running too lean or it will cause horrible damage. Running rich, fuel mixture wise and running rich, oil ratio wise is required for proper break in.
    The sparkplug should be black, but not to the point of getting fouled.

    I just pulled the plug an I think it's lean. the tip where it sparks is tan like the box it came in.

    Tan in color like cardboard, is very good for an engine that has been broken in.
    It is a bit too lean for my preferrance, but as long as you are running 16 to 1 oil ratio you should be ok.
    If you are just using the volume of oil in the Poulan bottle mixed with one gallon as the directions say to on the side of the bottle, that is not enough oil for break in. It is good for after break in. I believe their ratio is 20 to 1.
    To get 16 to 1 just do not use a whole gallon of gas to one bottle.
    Exactly how much gas I do not know off the top of my head. I would guess 7/8 gallon.

    Thanks GearNut
    it's a good size bottle of oil, I put 8 oz. in 1 gallon of I think 91 octane. I think that's correct for 16-1. maybe the synthetic burns different? I dunno. I checked the needle setting, it was at 2nd from the top of the needle. I bumped it to the 3rd, it ran ruffer, cud hardly drive. tried the 4th last notch, no idle, smoked alot, stalled. I believe flooding. so, I put it back, still runs same. maybe I'm askin too much from it at this point? after all, for the $ this is just too much legal fun! anyways, what kind of oil should I be using? I got the poulan cuz walmart was handy and that's all they had synthetic. I'm in st. Louis, anywhere cud be handy with this bike. haha!

    The Poulan oil is fine. There are waaaay better oils out there though. Do a search and check it out.
