whats up guys?

I just got a 2000 DS 650. I have a question about the gearing. It has a Big Gun exhaust, K&N, jet kit, and 20" Razr rear tires. The front sprocket is stock (16t right?) and the rear is a 38t (the previous owner said it was a 37t but I count 38). now the guy I got it from said it tops out at 83 mph. I ride mostly trails, some dirt roads, small hill climbs and once and a while an open field. I have no need or desire to go 80 mph, I need lower gears for the trails, right now 1st gear seems too high I really need to slip the clutch a lot. I am kinda confused on what sprocket sizes (and tires) I should run, any help? oh yeah the guy gave me the stock 40t rear sprocket so I have that to put back on...

thanks

 

good to meet ya

rockymountainatv has a 15t front sprocket for under $20. give that a try, should help

thanks, thats what I was thinking, but should I keep the 38 rear or put the 40 back on?

 

Just going to the stock rear should make a difference. Either a 15 or 14 (if you really want low gearing) front should get it where you want to be for tighter trails.

If you keep the 38 and go to a smaller front, your chain length might be off. More teeth on both sprockets will also help everything last longer. 15/38 and 16/40 are pretty close to the same gearing, but the 16/40 combo will last longer. Same for 14/38 vs. 15/40.

I just dump the clutch to avoid slipping it. Make sure you're good at riding wheelies before you go and do that. [img]i/expressions/face-icon-small-happy.gif[/img]

 

I am gonna put the stock 40t rear on there and see how it is, then maybe I'll get a 15t if I still want more low end.

whats the best setup for a wheelie monster!?!?

 

It's a ds so wheelie's are easy no matter what the gearing is[img]i/expressions/face-icon-small-happy.gif[/img]. I run 15/40 combo with razor 20's on the back and I think it is about perfect. I top out in fifth pretty easy, but that is rare to get there on the trails I ride. First gear will be real low and I run in second even hill climbing and other low speed activities.

I also have 2000 ds and stock gearing on it was 16-42 .

 

well, the guy gave me what he said was the stock sprocket, but I never actually counted to teeth. I will check and see if it is 40 or 42.

from what I have been reading 15/40 sounds ideal?

 

the stock sprocket on my 2000 is 40t. i just put it on and took it for a ride up the road, it is still crazy fast!! but 1st gear seems more usable for the trails, which is a good thing!! I'll have to ride it like this for a while and see if I wanna go lower, like a 15t front.

thanks for all the info and help!!

 

dondiesel444,

You'll like the 15 tooth front sprocket, I suggest getting the more heavy duty one from On-dunes.com, it's like $30 or $35. Be sure to get the extra lock washer, I figure each one is worth two uses then I will trash it because I certainly don't want to have it fail. The washer is cheaper at On-dunes than at the dealer as well.

Also remember that one tooth change is approximately worth three teeth on the back. One tooth chnage is about a 7% gearing change, if you have 22" tires as opposed to 20" tires the 22" tires are a 10% higher gearing change. I know you have 20s but I figure you might want to know this stuff for later.
