Any of you guys change out your compensator sprocket for more torque?? Just wondering. Baker sell two different sprockets. One 9% more torgue, and one 19% more torque. I have a six speed trans and wondering what sproket to go with.. My motor is pretty built but want more off the line power.
Thanks for the help.

Somebody else will probably chime in to help you. I didn't know they made sprockets for evos that added more torque.I'll subscribe to this post.

It changes the final drive ratio, gives better low end acceleration but less top end speed. I suppose that in doing this it gives you more low end torque. Probably not overall torque.

So they're just a bigger diameter sprocket? Not trying to steal the thread.

Probably a smaller sprocket. I think that's probably one of those things you'll just have to try to see if it works on your bike or not. With the 6 speed, depending on the final gearing, I could see that it might work out, but there's so many variables like your engine build, the gears in the transmission, final drive sprockets, etc. You'd just have to put one on and see what happens, but do expect higher RPMs at a given speed. I would think, anyway.

I'm running Ultima 6 spd with a 0.86 6th gear. 36T Clutch shell. Stock final drive 32/70. Started with a 25/36 primary. Slow off the line. Pinged at high speed. Engine felt like it was lugging at anything under 80, but pulled strong up through triple digits.
I wanted to run a 23T Comp with an 80 pitch chain (vice 82 which is stock) but it was just a hair too tight. Ran the 23T with stock chain and the adjusting shoe flipped, but that didn't work too well, so I went with the 24T. Works fine.
Dropping comp sprocket 1 tooth to 24/36 doesn't seem like much but the difference is noticeable. Less pinging at speed, better take off etc.. seems to access the engines power band better. FWIW I tend more towards highway cruising than hole shots. I liked the 23T better, but and 81T primary chain was choke cash.
Also, a comp sprocket is a comp sprocket... just a big hunk of metal. Kind of hard to mess up. Not sure what baker charges, but you can get pretty much anything on flea bay for cheap. When you start talking custom length primary chains and one off Comp sprockets the buckage adds up! A while back there were some Harley 21T comp sprocket/chain combos for a reasonable price. Probably get the wheel up with that! My 24T is actually the original that came with the bike in 87. 140K and still working, but if I find a new one that'll fit I'll probably swap it out in the spring.
Good luck getting it dialed in.

We usually go down one tooth on the tranny sprocket. That gets back some of the bottom end without sacrificing too much top end. Going down one tooth on the compensator would do the same thing. However it would also make the starter work harder. Remember the starter turns the clutch shell, which turns the engine over by turning the compensator. By going smaller you are losing mechanical advantage and the engine will crank a little harder/slower. Everything has a trade off.
If you have an electric speedometer and change the compensator, the speedometer will still be correct. If you change the tranny sprocket it will be off and a speedometer calibrator will have to be installed. Hope this helps.

Attached a nice calculator below, owners of the newer 6 speed Twinkees drop 2 teeth on the trans pulley to make 6th gear more useable, 99-01 efi big bikes have the primary front sprocket down one and the clutch sprocket up one tooth to get 3.34 and seems to be a gear ratio that several duplicate.
I agree with John on the 1 tooth drop for 5 speeds but with a 6 speed, the 2 tooth drop would work, I have both the 2 tooth primary change and the 30 trans gear with the 5 speed but my riding style is country roads, hills, run hard, big bike, big rider. Another gear would be ideal for my setup but still lives at 65 mph but as other mentioned, consider your riding style, engine output but if you like to accellerate, the 2 tooth drop is your choice.
