if you want to get a better power ration on our machines and not caring if top speed drops some , you can reduce the diameter and no. of teeth on the drive sprocket . is there anyone with experience that have a idea if going from say a 20 tooth sprocket to a 18 tooth will be a noticeable difference or does one need to buy 3 or 4 different sets of sprockets and just test each size. in other words will just a couple of teeth change things much or ? thanks , johnboy va.
On a bike, dropping 1 tooth on the drive sprocket is roughly equal to adding 3 teeth on the driven sprocket. It would make a noticeable difference. I was wondering if there are options for tooth count on drive sprockets myself. Is there enough adjustability in chain tension adjustment? Smaller drive sprocket will probably require taking a link or two out of the chain.
thats good info .... the design on my max 2 with the subframe makes it real easy to change the drive sprockets ( one for each side ) and easy chain adjusting . just trying to get a idea for tooth count without buying too many sprockets to experiment with . thanks for your reply ruffus . j.boy
I was going to drop down to a 13 tooth sprocket on the t 20 but the machinists advised against it. Not enough meat left after boring it out.
What it lacks in ground clearance it makes up for with traction.
yea ....the drive sprocket shaft on my max 2 is a 1 1/4'' keyed . is just a cutoff regular axle . i did originally use those clamping keyed sprocket hubs that use 3 bolts so you can change the flat tooth sprocket part very easy in order to switch sprocket sizes . they actually work really well . i think i'll drop down 2 tooth sizes and see what that does for performance . , etc . i don't need a fast top end . not even sure what my top speed is now . j.b.
Divide your your two sprockets to get the ratio.
IE a 45 tooth and a 15 tooth be a ratio of 3:1
Thus your 2nd sprocket is just as important and its hard to know the outcome without doing that simple equation.
From there the 3:1 2.25:1 etc will tell you what you need to know.
I've dropped the stock 15 tooth transmission side sprocket on both of my Coots I like how they drive much better now. 12 on the Diesel and 11 on the gas Vangaurd.
Makes it a lot easier for the CVT belt to not slip as well. That's pretty much my rule of thumb gear down until the CVT belt won't slip except in the most extreme situations. Gives a lot better control as well.
In the places I ride, you'll forget you even have a 2nd gear speed is so irreverent with how technical and rough it is.
thanks allwheel ... thats the info i needed . never thought about the belt slip , makes sense . if most of someones riding is in deep mud or snow or up hills , speed is not really needed . i guess the main thing is don't gear so low that the motor has to wind out to go at a '' turtles pace '' . sprockets are'nt that expensive so a couple of sets to get it just right is no big deal , thanks ..i will post results when i get it done . johnboy va.
I have one this way Tbone. It's in a racer and takes some serious abuse and It's held up just fine.Originally Posted by tbone9
