Well I saw ESFR pro xr rider post about picking up some helixs and springs at the Big East show. I figured I should do the same. But I need some suggestions on my sled, Carl's is building me a 660 right now and I haven't gotten any setups from them yet. I need some clutching and gearing setups, I have a Pro XR 660 with SLP twins, 136" 1.25 Ripsaw. I ride mostly trails and do some of trail when I can. I want it setup to run corner to corner and still have alittle top end left.

from what I hear the 660 keeps with 800s til 80 then starts leaving THEM behind. Maybe try 23/43 for accleration and I bet you will still have some nice topend left.
Stick with stock 23/39. Good combo considering you long tracked, but then compensated by adding more power. It'll be a stump-ripper with that setup. 23/43 is WAAY too low. You will not be able to control track spin like that. I rode a 660 with 22/40 and it was nearly unmanageable.

Ya I guess that is really low. Probably with the 660 kit go back to stock or leave it since the 660 makes amazing power and I doubt you will feel the need to regear but I have never felt it from the seat of pants.

Run the stock 24/41 or 23/39. The 23/39 will need a shorter chain. Run 62 weights, almond/blue, silver/blue #3, and a HSP36X, or dalton 52/36 helix. Something in that area. This should put you close. Most with stock single run 64's well, and you need more helix than the R11, but the same finish angle.

Sorry, saw the list of parts he has and the R11. With the team, same primary, but a 140/220 secondary spring, and a 66/44-.46, team #420494 would give you the option of a shallower finish angle to try. The team #420719 may work well also. It will be a bit different than the 600 with the added torque of the 660 down low, but with the twin pipes, it will not like a lot of helix angle at top end.

A well setup 660 whips a fairly stock 800 starting off the line all the way to top speed :div20:
I'm running 23/40 gears and am going to try 24/39 again this year. No need to go lower than 22/40. I really like the SLP 66/44.56 helix with my sled (I've literally tried a dozen or so). Worked well even when it was a 600.
I have 168 studs in the 136 ripsaw, so hook up won't be a problem. I have both a 74 and 76 chain. 23/39 is stock 600 gearing, I ran 22/39 in my 600 edge last year and it ripped. 25/41 is stock gearing so 24/41 that is in it is just dropped a top tooth. What about dropping another tooth, 23/41. Anyone have a polaris gearing chart you could e-mail me- [email protected]?
