Best gear's ratio.....

[yamstock1]

Stock gears are 21/39.... what do you think is the best ratio if I want to change gears set-up???

 

[Deadman]

what do you want to achieve is the real question?

 

[yamstock1]

I will have a Camoplast HawkSaw 1'' and I would like to gain highspeed....

depends on your weight

23/39 if your 195 or lighter

22/39 if your 195 or heavier

I'm 180 pounds and it's exactly what I would like to put 23/39... I think it's a good ratio for groomed trail...

Thanks!!!

Too high unless you are adding HP via exhaust, intake, etc. Go with 22/39 or keep stock chain and go 22/38.

22/38 is almost the same ratio than 23/39 and if I can keep my stock chain, it's less expensive, so good idea too.....

21/39 = 1.86 stock
23/39 = 1.70 ratio
22/38 = 1.73 ratio

I'm not adding HP but I will run with a Camoplast 121 X 14 X 1'' track.... it's almost like adding HP....

20/39 Ratio 1.95 I guess this is only for bigger lug tracks.

Like we have heard before, better gains with clutching but going up a gear should be a plus for stock or less track.

i put a 22 on mine........I like it, but would agree with Mr Ulmer. I didn't test as many clutch and gearing set ups as he did last rear but using my own sled as guage I would say 22/38 would be about as much as it can pull and still be fun on the trail.

let er snow already

Going down w stock chain

Hi!

How far down could I gear w the stock chain? 20/39? Lower? What is the limit without replacing the chain?

FYI Going long+widetrack.

You need a new chain going down 1 gear on top. Nytro has no top end torque(torque really falls of huge as rpm,s get higher) so it works better with lower gearing

 

[unpride]

I went 22/39. I weigh 180lbs. but with gear I will be about 200lbs if not more

What is the ratio with horse power? Is it a certain amount of change per so much extra power? I am sure it is based upon the type of riding you do also. But just for a nice mix. Mostly trai, some ditch banging, and a little bit of ice. Lets say for conversation.

According to the servicemanual you can go as low as 18/39 using the stock chain with 68 links.

Edit: I just realised that you are referring to gear ratio, then i guess it would be as high as 18/39 ratio 2.17
