300 ft sand gearing

[mx1986]

I have a ten mil cub with a mild drag port on alky with a drag frame 12in front 15 out back. i have stock primary ratio. 25in x 12 x 11 extremes.

 

My question is what would be a good sprocket starting point right now it's a 14 40

[m671054]

clutch setup? tires are 25-12 11paddle?

[m671054]

override 1-5 or 2-5. what gear do you olan to leave in

[LilJockey481]

16-41 leave in 2nd

[SlowerThanYou]

Most leave in 2nd, but it can be done well in 1st also.

[camatv]

im to fat to launch 2nd gear.  i break the gears all the time.. 

 

1-5 is way better in my opinion.  after you figure out how to make them work it for you.

No 12 paddle. R1 clutch 10 plate billet basket. I don't have a lockout clutch yet cuz I haven't bought straight cuts primarys gears. I weight 155 pounds.

[mx1986]

I also have some 12 paddle extreme staggers that r 81 ro. The regular 12 paddle extreme r only 79 ro

[SlowerThanYou]

R1 clutch 10 plate billet basket. I don't have a lockout clutch yet.

 

IMO, that's way too much clutch. When you start getting over 700cc or smaller nitrous/boosted engines you can start using that many clutch plates efficiently. 10 plates will work, but pretty hard to get slip out of them. Then you carry the penalty of accelerating that extra weight.

Way to much clutch in my opinion. 17-43 2nd gear stk primary ratio.

We built a 4 mill cub with cleanup port work. 2-5 override in a stock chassis +10 out the back and stock j-arms. 14 sat extremes 75 ro 15-47 gearing. Went 4.26 with a 240lb rider. Bike weight rtr was 307

Staggered**

[possum]

what mph was that at and running out in 5th 10dmbanshee? 15-47 vs 17-43 is a big difference

[m671054]

12 extreme vs. 14 extreme and 4mil vs. 10 mil are the reasons for gearing recomendation differences

[m671054]

And 10 vs. 15 out the back
