why not? sure it'll work, but i'd put the correct 20" rear wheel on it.
Do you have any idea what a mint condition, all original sears screamer is worth?
both of my bikes are 20" frames with 20" wheels and i'm running 41 tooth sprockets on both of them.
if you plan on keeping that 16" rear wheel, you will have to go down to a 36 tooth sprocket or smaller to get any decent speed out of it.
if you put a bigger sprocket on it (like a 44 tooth or bigger), with that 16" rear wheel it might wheelie like crazy because it will have so much bottom end torque.
I would get it and put a 20" rear wheel on it with a 20x2.00 cheater slick and run a 44 tooth sprocket.
both of my 20" bikes will get up to 30-32 mph with this size sprocket.
I have seen mint complete, original sears screamers got for a $300-$400. they are definitly expensive, but not in the schwinn Krate category.
I can tell you right now tho, that the engine that has the intake manifold will be a problem. There won't be much (if any) clearance between the air filter and the seat post tube.
I have the version of the 50 c.c. 2 stroke that does not have the intake manifold (the carb is bolted right to the cylinder) and it is still a tight fit on my 20" frame.
if you look close, the bottom frame tube and seat post on my bike are at about the same angle as the ones on the screamer. look how close the air filter is to the seat post tube on my bike.
I have a low profile air filter on it and no intake manifold tube.
That's an awesome bike! What kind is it? I'm not even a big fan of small bikes either. The guy sold the bike apparently because he didn't reply. Was it worth $150 based on the pic IYO?
I've seen those 49cc with no manifolds, and remember reading that customs snagged a bunch of them so they haven't been around?
What kind of carb did they come with? Are the bolt holes spaced to equip more aftermarket carbs? Any problems with blow-back?
