The Everything Breakout Thread
Typical cost, $300 parts & labor for front pulley swap, and another $100 for the rear pulley swap assuming you DIY the rear pulley change. otherwise add on another $70 in labor. Still, that's less than the cost of a fancy air cleaner for much better acceleration and ZERO downside.
STOCK INFO:
Breakout primary gears stock:
34 on the compensator, and 46 on the clutch bucket.
Breakout secondary pulleys stock:
2013 to present FXSB - Pulley F: 32T - Pulley R: 66T
Breakout drive belt:
Belt width: 24mm Length 133T
UPGRADE PARTS:
Front final drive pulley: 30 Tooth Tans Sprocket
2011 Tri Glide Trans Sprocket is P/N 83595-11 $63, discount avg. prices HD-83595-11
Primary complete gasket kits needed:
Inner kit - Harley Davidson 25700226 GASKET KIT, INNER PRIMARY $43 avg price
Outer kit - JAMES GASKETS, INC. JGI-60547-06-KF GASKET KIT PRIMARY COVER $50 avg price
Drive belt:
You can use the same 133T belt if you do both the 30T front and 68T rear, or, leave the stock 32T front and do the 68T rear pulley. If you only install the 30T front and leave the 66T rear, you must buy a shorter 132 or 131 belt.
Labor costs:
Local HD dealer (Barger HD in Canoga Park, California) quoted me $135 labor for the install assuming I have all parts.
Local HD dealer (Glendale HD in Glendale, California) quoted me $150 labor for the install.
Both dealers stated it is about a 1.5hr job
I called a local indy shop - "Born Free Cycles" in Burbank, and was quoted !$350! for labor only. WTF?
Ratios and RPMs
The overall drive ratio will change from the stock 2.79 to 3.067 (9.899% shorter gearing = NICE!).
The RPM's with a 30T front and 68T rear in 6th are as follows:
60mph 2420
65mph 2621
70mph 2823
75mph 3025
80mph 3226
85mph 3428
90mph 3630
Rear Pulley upgrade:
See my previous posts in this thread for the rear 68T sportster pulley (P/N 40444-07) upgrade and the shorter five hub bolts (P/N 3899). Easy to DIY on the rear pulley with basic tools.
Speedometer:
Your speedo will be off by 9.899% with the new 30t / 68t combo vs the stock 32t / 66t so you'll need a TTS / PV2 to change the calibration, by adding 9.899% to the stock speedometer value of 2115. You may want to add another 3 or 4 % to account for any factory deviation, as HD allows for up to 5% discrepancy.

I also did some more digging and this mod will actually improve MPG in town (less tq/hp effort to achieve a given speed), and will not affect freeway MPG. RPM is not a dictator of MPG, fuel consumption (e.g. heavy wrist) is.
Thanks for the compliment brah.
As you know, it's an ongoing project (they always are) lol. Keep talking myself out of ordering the exile mid control kit for softails.
Trying to save my dough for a car purchase in a year or so.
