What would everyone recommend for sprocket combination if I went from 22's to 18 on my 1982R. I assume it's got the stock sprockets now. I plan on running it on ice with the 18's.
Any input much appreciated.

Go up 2 teeth in the front, or 6 in the rear.

What are good sources for sprockets and/or chains?

I went 2 teeth up also and stayed stock on the rear on my 85 350x works great Its about all it will pull is 2-3 inches of snow need a big bore

Sprocket Specialists- No BS.

My 81R has a 15 tooth up front with the stocker out back I beleive, and the tires are equivelant to 18's.

This is a good question I too have, but for my 200x? I went from stock tires to 18 inchers, should I drop 3 in the back and add one up front since I am replacing both sprockets and the chain? The 200x won't be stock either.

If you are buying a rear anyway and going with 18's I personally would go as small as possible on the rear to get back a little ground clearance. You can always interchange countershaft sprockets at the front easily and inexpensively compared to the rears. You will likely NEVER go back to 22's once you ditch them anyway.

I used Sproket Specialist....order any size, and weight you want. Nice piece.

when you change sprocket sizes, make sure the chain you buy has extra links. I would order it a little long and cut it down to fit your new sprocket sizes.

THe biggest he can get on an 82 R and still use the countershaft cover is 15 teeth, and even that's tight.

how was that a response to curtis's post...or did I miss something.

Because Curtis suggested going as small as possible in the rear and then just changing the front sprocket as needed because they are cheaper. I have recently learned that on early R's the biggest front sprocket you can run is 15 teeth, limiting your choices.

It isnt all about being cheaper but much easier to go up or down a tooth without having to add or remove chain links. The cost is a bonus too. If you drop a bunch of teeth on the rear you will likely not need to go big up front anyway.

It depends on what you're going to do with it. Just going for top end then you want to keep gearing the front up and the back down until the engine won't pull it anymore. If you're racing a small circle then you might want to leave it alone. If you're running a bigger circle then you will want to go more towards the top end type set up. If you go from a 22 to an 18 you have changed your final drive by about 18%. In order to make up for it you'll have to increase the front sprocket's size by 18% or reduce the rear by 18%. Of course, you could do a little of each but then you're getting into more math than my high school educated brain cares to deal with.
