hahaha hell yeah. Ive known of people to try and take every little unusable thing off their car to make it quicker. Surprised they didnt strip the paint as well. Yet they weighed 500 freakin pounds. People are weird.

Just a few examples for you to think about.
The 113 is a very poplar build with racers.
If it is build right they are serious tq/ monsters.








this is just a few and you can see they were tuned by different tuners and different cams.

I think it is true that you can spend a lot of money on better parts and not notice big gains in power but I think if you can run to the cost of better rods at the time you are getting crank work it is money well spent.
Very well put. The thing is I decided to to do all at one time. It has taken me months of saving, and work. When you put all the small things in order plus the big things all at once you get more bang for your bucks. Least wise that is how I see it.
Yes it is a reworked crank Welded, pined, trued and balanced. The engine has tim.. bearings. I was close to getting a new brakeout cvo but decided to do this instead. Save a bundle doing it this way. I piked up the 05 super glide with 11,000 on it for just under $6,000. I have a cvo SG for touring and my wife has a ss106 wide glide to ride around locally. This is my toy to play on.


Oh, we only have a 1/8 mile track up here so 8 is in the 1/8th. I should have disclosed this. All 3 tracks close by are 1/8th tracks. High 11's to low 12's sounds about right in the 1/4.

Im not, although SOME harley riders are fat. Some people become harley riders just because they would look regoshdarnrediculous on a sportbike.

In a word, YES, it can affect horsepower in a myriad of ways. Too tipsy and too lazy to discuss them right now, but let me suggest a dissertation on the kinematics of machinery, many of which are available here on the Web.......
