    I've got a 44T sprocket now and it goes 30mph. My bike's a pretty solid set up, handles awsome! I kinda want to go faster. I need to get a new wheel for the back cause it's an old Schwinn S-5 and I'm having a hard time getting some nice new white walls that will fit it. So, I'm going to switch to a standard rim, and I thought why not throw a 32T sprocket on there while I'm at it, but how do I get one and how much are they?

    If I take It down to a 32T wont that take me up to 45mph, and I don't see a 32T for sale. I want to get this thing as fast as I can but still stay reliable. It's safer to go faster on these things because your speed differance with the other traffic go down. The slower you are the more likely you'll get rear-ended.
    What would it take to have one of these things machined?

    If you do a google search for sprockets, 415 chain, you will be ablwe to find several places that sell "blanks" with just the teeth and a 1" hole in the center. Available in any number of teeth for not too much money. Mark and drill the bolt holes yourself.

    I dont see why you want over 30 that would pretty much make the bike illeagle to ride on road....but thats your choice but with more motorbikes gaining more attentain we as the founders of the new movement need to try to keep thing in check......the Chinese motor is more work hourse than race hourse

    the 32t sprokets are out there, l have one that l will be using on another trike, but these sprokets are hard to come by, try spookytooth he may still have some left...............later

    Just put a 24 Tooth sprocket on my OCC Pacific. I bought it last year at 1977 Mopeds in Kalamazoo. I did have the 44 Tooth on and it gave good performance for accelleration but I have joined a moped gang in K.C. the Breakfast Mafia and its no good getting left, struggling to keep up with the engine screaming its lungs out. The routes that I had ridden with them didn't feature many hills so I figured I was good. First starting takes a another ten feet average as a higher speed is required before engageing the clutch. The accelleration is also slower but can be compensated for by pedalling, keeping me with the pack. Top speed puts me right up front racing with the fastest mopeds which is a rush. Though I currently have to back off before stoplights due to lower braking capacity. Then the bad news, starting at the bottom of hills from a stop is not for those who cannot Armstrong their way to the top, the 49cc and 24 Tooth is not for hilly areas. The last Sunday weekly ride with the B-Mafia had a couple of long hills, one I pedalled, the other I walked (wishing for more cc's) .The engine is quite comfortable with the sprocket under normal conditions, at top speed the engine doesn't rap out but instead seems to keep gaining with the power band starting at about 20 mph. I'll have more accurate speed data when I get the speedo hooked up. Note:the wider rear sprocket required use of a 40-1 x 10ft (5ft of it)roller chain Farmex #06401 which kinked alot initially on the front sprocket but worked fine.

    thats why l use the 36t sproket, goes up hills, easy to get started, great for top speed, all around a great sproket to use..... P.S. due you have slack in your chain? mine will fly when the chain is loose, when its tight it just sux.....later

    Yes, I got some slack and it seems to work pretty good.

    did you call spookytooth about getting a 32 or 36t sproket? he's the only one that l know that would carry them.

    I found a site that has all sized of blank sprockets. I looked up the #415 chain and they had every number of teeth you wanted for About $22. I might go with a 36T just to get my rpm's down when I'm at 30mph. I still would like to go fast though. I think my next project will be converting a new Schwinn StingRay into a "Motorcycle." They make a sweet springer frontend for those that can be easily modified for the extra wieght of a Briggs & Straton engine. The frame design is ideal for a flat motor mount just like a minibike. It's a three piece crank so you can use the bottom bracket as a jackshaft. Shimano makes this sweet 8speed hub that is strong enough to handle 5horse, but I don't know if you can lace that huge hub into one of those fat rims. I'm gonna do some more research but that's what I have so far. If you get the right sprocket set up there's no reason why It wouldn't be able to go 60mph down the road.

    I just ordered a 36T sprocket from Thatsdax.com!! I have been using the 44T sprocket that came with my kit and it seems that my max speed is around 32 MPH. I cruise around 27 to 29 due to the fact that I don't want my engine blowing apart from the max throttle vibration and RPMs. :) I read this post and it encouraged me to go ahead and purchase the 36T sprocket. I will post my results when I receive and install it. BTW, will I have to cut more chain links off or is it not much difference that the chain tensioner can't take care of?

    chain length is unique to each build, but i'm guessing you'll be removing 6-8 links for a clean job...keep us posted 8)

    32 tooth

    i run a 32 tooth sprocket. the chain has to be cut a lot shorter.
    i would not advise anyone just to put a 32 tooth on a standard engine as it will just bog down and you will struugle to get the engine to rev.
    i have had to do a lot of mods to get more power out of the engine so it pulls off better. my sprocket was a 420 size and had to be turned down to a 410 to fit the chain.

    slack on your chain is bad, i had slack on my dirtbike chain and eventually it destroys your sprocket, this is because it gets cought before it it rotates off the sprocket and basiclly sharpens it to a very sharp point, but then theyre weak so eventually they break off...just some advice...

    I installed my 36T sprocket from Thatsdax and it is pretty nice. I use the bike to commute back and forth to work, about 19 Miles a day. Before with the 44T sprocket, my engine would sound like it was about to implode at 31 MPH and my upper wrist pin bearing eventually shredded on me taking out the cylinder, piston, and rings. With the 36T sprocket I am able to cruise at 30 -32 MPH with a tolerable RPM rate and lower vibration. I think the gas mileage is better and hope for longer engine life. I painted the sprocket to match the bike frame and filed the tips down. I found that engaging the engine can be done smoothly as low as 8 MPH. I would defintely recommend the 36T sprocket for those of you who want to go a little faster without constantly red-lining the engine.
    I also think that pulling the clutch in on down hills vs. letting the engine break and keep you slower is easier on the internal engine parts.
