. Anymore or less than 3 teeth will change the gearing noticably. In Germany B had a 15 teeth front sprocket! The best overall gear ratios for most purposes on all series are 15-43, 16-45 or 14-40
The small 9-hole sprockets come in two sizes, 44 tooth and 50 tooth. The inner diameter is 1.39 and hole spacing is 1. See table below for specifications. The small 9-hole 44 tooth sprocket will come with the SkyHawk Angle Fire 2-stroke engine kit To turn the rear sprocket once, the counter shaft sprocket has to spin the number of times in the Ratio column. (see gear ratio image) As an example, a 30 tooth rear sprocket and a 10 tooth front sprocket equals a 3.00 gearing ratio or three rotations on the front for every one rotation on the rear Sprocket Ratio. Jump to Latest and cause the wear to become more and more uneven. Having factors in common, such as both sprockets divisible by 2, or 3, will cause some of the same effect, but not as badly.

I would like to try a different rear sprocket on a 250 exc for mx. Currently the rear is 50 ( front 13), which direction should I try first, either a 52 (4.0 ratio) or a 48 (3.69 ratio)? I know the exc has a wider gapping in the box than a sx so will yield different resu..
only you can decide.would you rather give have a bike that is easier to get traction on and have a more topspeed or would you rather a bike that will spin the wheels of. i personally like really tall gearing. on my yz250f i run 14-47 (stock is 13-50) for mostly woods i like tall gearing because for me it is easier to get traction and what not, you might have to work the clutch a little bit. Check Lock Centers and adjust sprockets - Chain links will adjust to maintain nearest to current Sprocket Centers. Tire Diameter on Large Sprocket mm inch. Max RPM. RPM Small.

. For example, as you'll see in the chart below, if you have 40 teeth on the rear sprocket and 10 on the front, you get a ratio of 4.00. 40 ÷10=4.0 This 13/50 gearing would be lower than either 14/52 (3.71) or 14/53 (3.79) at a 3.85 gear ratio. Most MXA test riders try to gear their bikes so that they can use third gear on the bike more. To obtain your gear ratio is simple, you can use the chart provided below, or simply divide the number of teeth on the rear sprocket, by the number of teeth on the front sprocket. For example if your rear sprocket had 40 teeth and your front sprocket had 12 teeth. 40/12 = 3.33, your gear ratio would be 3.33 Ryan switches between riding 4-stroke and 2-stroke dirt bikes, but as of late heís been spending a lot of time on the saddle of his two-stroke-powered 300cc Gas Gas dirt bike. He told us he really likes running a 14/52 setup on his bikes; in other words, 14 teeth on the front sprocket and 52 teeth on the rear sprocket

Reduction Ratio: 3 to 1 chain reduce A very common gearing modification to this arrangement is to go -1 tooth on the front sprocket and +2 teeth on the rear. This leaves us with 15/50. The gear ratio is now 3.33:1, meaning the front sprocket has to rotate 3.33 times before the rear sprocket rotates once. As a decimal number, this ratio now becomes 0.3 (15 / 50 = 0.3) The higher the gear ratio number, the lower the gearing. Thus, the 3.77 of a 13/49-tooth combo becomes a 4.00 if you add three teeth to the rear sprocket (13/52)

As a general rule, most 2-stroke engines these days use a 50:1 fuel mix. This is a mixture of 2% oil in the fuel or the same as 100ml of oil in 5L of unleaded petrol.
