gearing issues

[stiz]

a buddy of mine just went from a 121' track to a 151' and we got into a big argument about gearing i was just wondering what you guys have to say about it. the gears in the sled are 39-23

 

[maxwell]

are you sure about that. sorry i guess 23/39 makes sense.

either way not sure what size motor he has but if its an 800 i would start off with something around 19/43

sorry hes runnin a 600

ok... well 19/43 or 19/45 will work good for him. in the mountains anyways

He's probably not low enough, especially if mountain riding. Some where around 2.0 or 0.5 (depending on which way you prefer to calculate) would likely be good at a minimum for mountians.

how heavy is he. 19/45 would be my recomendation. what size of drivers does he run.

Going to need a strong 600 to pull a 151 in the deep snow. I run 19-44 in my 700. Good luck.

He is geared fine for the trails, but way too high for a 600 to move a 151" around the mountains. Depending on the sled there are many options, but the 2.0 to 2.05 suggested above is a great place to start. A 600 and 151" track is going to take a lot of work to get the gearing and clutching right for the mountains.
