Which end do fcr's help the most?
      #572767 - 08/31/12 05:38 PM

Do they help on the low end more or the top end of the rpm range.

Will i lose any low end acceleration?

What part of the FCR"s will i like the most?

I might get'mm next week.(good things come to those who wait!

1. Top end more than the low end.
2. No low end loss if properly tuned.
3. Presuming you get them dialed in properly, the power increase.

You will also find the FCRs do not like to be "whacked open".... they do like to be rolled on and you can roll on fairly quickly.

Great first mod!

I agree, "whacking" them open results in horrible rattling
Noises from the carbs. The smooth roll on however results in
Awesome acceleration and much smiling.
