Anyone tried this yet. While researching for Don's transmission options, I spent some time looking at this. It seems like a really good mod. It can be coupled with a trans pulley/belt change for regearing too. Looks like it make make a good winter mod. Chit man, I'm running out of stuff to do already! And won't be doing a fairing either!

Baker F6F for HD Cruise Drive Transmissions:
http://www.bakerdrivetrain.com/f6f/index.htm#sp9Loud fifth gear is a very common complaint with stock Factory Six-Speeds. So BAKER DRIVETRAIN has stepped forward with an upgrade that will surely make your stock transmission sound so quiet that you’ll think BAKER built the whole dang thing! Our kit features helical cut diamond ground gears, 28% wider bearings, a 1/8” thick bearing retainer plate, and a billet aluminum bearing door. All this combines to give you the advantage of a quieter 5th gear, and no clutch lever walking.
Additional features that the F6F offer are:
No 5th gear whine
Reduces drivetrain lash in 5th gear
Stylish 12 pt. ARP fasteners
Fully chromed billet aluminum bearing door
Quiet diamond ground gears
Heavy duty bearings
No wimpy snap rings
Direct bolt in assembly
BAKER Recal box – INCLUDED!
Reduce Noise:
The answer for your Harley-Davidson Cruise Drive to Upgrade that Noisy 5th Gear. Smooth it up and quiet it down.
Add Strength:
Engine builders are finding the F6F is a necessary part of any moderate, or greater, TC96 engine performance work. With increased power output the axial forces from the helical gears, especially in 2nd and 3rd gear, increase significantly to the point of deforming or breaking the snap rings in the door. The F6F uses a steel plate with 6 screws to positively secure the bearings against the axial thrust forces generated by the helical gears.
The F6F Kit includes:
Smooth Helical 5th Gear Pair
Billet Door for Strength and Rigidity
Heavy-Duty Bearings are 28% Wider than Stock
Steel Bearing Retaining Plate replaces OEM Snap Ring Design
BAKER Speedo Recalibration Box
12-Point ARP Fasteners
2-Year BAKER Limited Warranty
Available for the 2006 Dyna, and all 2007-up H-D models (excluding Sportster and V-Rod) with the 6 speed transmission.
All that wrapped up with BAKER’s dependable and unbeatable 2 year warranty; and just in time, too! Released December '06.
And here's the info on the pulley changes:
30-tooth or 31-tooth h-d® 2006-up cruise drive™ pulleys
Get more oomph from a throttle-wick on your 2007 stock Harley-Davidson FL. Our 30-Tooth or 31-Tooth transmission pulleys effectively ‘gear down’ the bike to optimize the performance in two major ways.
First, you’ll get more torque and power from the take-off gears. This remedies the common criticism of the new bikes being a little sluggish off the line for some riders.
Second, you can utilize the 6th gear at a slower, more reasonable highway speed for a more comfortable RPM. These pulleys bring the cruising gears down a notch for finessing your ride.
Performance details are as follow:
Increase Rear Wheel Torque (30T- 7% Increase / 31T- 3% Increase)
Cruising RPM 6th gear (75MPH) 30T @ 2830 / 31T @ 2756
No more lugging the motor in 6th gear at lower cruising speeds (60-70 MPH)
Note: Will require the use of a 1 tooth shorter belt (For example: H-D p/n 40056-07 is for FL) 2 ¼” special Pulley nut socket required for replacement available from Baker Drivetrain. p/n 94660-07BD
Hoist!
