With the later closing intake event on the .510, the low-mid torque will be toast, and in a heavy bike, it'll only take a few miles, of fanning the clutch lever, and gear shifter, to become painfully aware of the fact that the OE cam had more power, in the low-mid range.
The .509 was designed to be a plug/play in an 88", where torque is needed, and we've seen 92-94 ft/lbs from those once tuned.
Not trying to sell product, and no pony in the race, just sharing info from 30 years in this business.

Anyway, thanks for your thoughts. Do you guys offer a mail order cam package with all you need to install the cams?

Thanks for chiming in - and what you write makes sense to me, with the huge split on those cams I can see that they are going to be high RPM cams. Frankly the big split on the 509 seems a bit odd to me - admittedly I am not a Harley cam expert by any means but I'd think such a big split would be crutching a weak exhaust flow, and to my knowledge, the Harley exhaust flow is good?

But I'd trust you experience. I will look on your website for a cam package kit.

Not good for a touring wanna race ha ha I no the 510 wakes up about 2000 rpm but then she keeps on going get what your saying need more on the bottom end for the heavier bike but like I said make it a 95 bigger pistons the right mods she goes real good.

Why is the 510 not good for a Touring bike? The guys at S&S told me it's better than the 509.
