ATTN: Don't Gamble When Buying Performance Parts
When you’re ready to add more power to your Milwaukee-Eight, a great place to start is by increasing your displacement.
There are products out there that could set you back $6K+ but you can get top quality USA products from one of the worlds most trusted performance parts manufacturers for much less.
S&S Cycle have been around since 1958. They established themselves as a leader in performance parts for V-Twin Motorcycles 60+ years ago and have retained that position through constant research, development and testing.
I’m not saying all of this to impress you but I think it’s important to know who stands behind the products you buy and use.
These S&S big bore cylinders are precision honed & use USA Made CP-Carrillo Pistons. There is no need to bore stock cylinders & make the cylinder spigot paper thin.
By using their own proprietary cylinders, S&S can increase the bore size whilst maintaining cylinder strength & integrity.
You can’t shortcut performance.
Don’t pay large dollars for an item that is altered from its original engineered specs. It may have new weak spots and it’s unknown what warranty is attached, the original manufacturer wont covered an altered product.
I could understand someone with old beat up bike gambling on it if the part was way cheaper than average, but why pay more and take on that extra risk on a Milwaukee-Eight?
Paying too much is avoidable. Gambling on performance parts is not worth it. Risking your Engine is CRAZY!
Why would you do any of that when you can access Top Quality Performance Parts from a Leading Manufacturer with better pricing?
