H-D tire shredder - why so LOW HP?
 

Looking to purchase a tire shredder kit on my Low Rider (103 cubic)

One of my considerations is leaning towards the tire shredder kit, but noticed the dyno graph on the website shows comparatively low numbers to even a fuel moto 107.

Anyone know why?

Am seeing the kit will be with 10.2 pistons compared to 10.8 on the 107, but that cannot alone attribute to almost 15 hp difference, am i right?

sorry for the typo in title, i meant to say LOW instead of love

any possible way to edit thread title?

EPA and warranty compliant is the reason it lags behind virtually any comparable aftermarket setup

so is it something that I can mix & match internals to build something 120/120 sized?

I like the 58mm throttle, and 110 sleeves.

Willing to buy separate items, cams, pistons to piece something fast!

Get an S&S 124 kit. Not only will you gain more cubic inches than the HD kit but they use better materials in the parts and the kit will help give peace of mind by replacing some of the weaker links in the stock twin cam motor. Like the crank lol

well it's triple the price. haha

I have a good price at the local dealer, and would love to preserve the H-D engine of my bike.

I want to be honest when I say, I ride harleys. not so much I ride S&S

Your choice, your loss 👍👍

Don't waste your money with HD engine parts. There is so much better aftermarket parts out there. I would call a reputable engine builder and speak to them explain to them what your looking for and they can build you a motor for your riding style.

That's fine as long as you don't mind riding in the rear of the pack. S&S is the better choice.

so what's the key differences between both?

I mean they're both 110, big bore, 58mm throttles, what is the thing that makes one more reliable and greater in deliver than another?
