I am wondering how to set up my sled for a low end/ mid range area. i really want some fast acceleration and good mid range to open up quick in the fields. Any help will be appreciated. thanks, Liener

there are kits you can get that will keep your front skis down, which increases your topend. the A.D. Bovin suspension kit, my new sled came with it and it has awsome acceleration

What year of sled do you have? Carb or EFI? How much $$$ do you have budgeted?

I can let you know what you need, as soon as I know what you have!!

just get a pair of springs from hp, orange/white primary and a green secondary. also some cat 51 gram weights. you can use the stock cat helis with the spring advanced in the 4 slot.

it will run you like 80-100 or so and will be fast.

Is this an actual kit or something just put together by someone else? 51g weights is considerably less weight than the stock 63.5g.

Keeping the same helix and adding stiffer springs is gonna make the stock setup over rev as is. Drop the primary weight by 12.5g is gonna make it over rev that much more.

You sure you have the right weight?

EDIT: Do you have any experience with anyone running this setup? What RPM does the sled leave the line at? How about top RPM?

thanks dp that was an f5 setup

66s will work better. cat p/n 0746-669

No harm intended - just didn't add up!
