Is the 36 tooth sprocket really worth it?

[S.PadreSurfer]

Hey everyone. i have the dax 50cc china engine with the stock 44t sprocket, and i was looking at their 36t for $29.99.

And i was wondering.... Is it really worth it?

Where i live there aren't any hills i would need to climb or anything, and i would like to be able to cruise a little faster without so many rpms and fuel consumption.

How many more mph's will i get?

Thanks..

and you can figure it out for yourself

Use the gear teeth count of 20 and 82 for the 2 stroke which = 4.1 to 1
that is for the internal gears under the clutch cover

At 6500 rpm on a 26" wheel you will get about 6 mph more

sorry, as you can see, im new to this.... what exactly goes where in this calculator?
please bear with me... lol

In a word...yes. Your terrain and objectives are perfectly suited to a smaller sprocket. It also depends on what size you currently have. If you are going from a 48 down to a 36 you will notice a huge difference.

Did you click the Help Button at the bottom of the calculator?

Help for Gear Ratio Calculator

Enter tooth count for up to 3 gear/chain sets. If you have less
than 3 gear/chain sets leave the unused fields at the default
value of 1:1.

If you're using a belt drive enter the diameter of the dirve and
driven pulleys in place ot tooth count. Any ratio will work and the
diameters can be entered in any chosen unit of measure as long
as the drive and driven pulley diameters are entered using the
same unit of measure.

Measure your wheel diameter for the most accurate speed. Using
the diameter printed on the tire can introduce errors.

For friction drives use the diameter of the friction drive wheel, not
the size of the driven wheel, as input to the wheel diameter field..

In a word yes.

Just to have the extra speed on hand if needed and have the engine running less hard at cruising speeds.

But it depends on your area too. Where I live there isnt anything close to hills.

each tooth is about 1 mph... meaning if you swap a 44 tooth out for a 34 it will go about 10 mph faster! I'd say thats worth the 25 bucks, no?

Thats true. I went from a 48 to a 36 and WOW what a difference. I then went from a 36 to a 34, and I can still notice the slight difference.

Oh only thing is, you cant ride too slowly with the taller rear sprocket, but thats fine by me, if I have to go slowly, I use leg power anyway.

thanks everyone. I'm going to purchase the sprocket.

Do you think dax is the best place to get it from?
