Honestly, I feel like if the 107" in my RK ever goes to **** on me, I'll stuff a 124 in that but I'd like to keep the Road Glide extremely dependable and dammit, 100/110 area.

Now don't get me wrong........I WANT a 124 in that bike, but most importantly I want it do be a good runner and not married to the builder if that makes any sense as I'm no mechanic and put on 10-15,000 miles a year.

Or should I just get the 124"
S&S Cycle T124LC (585 cams / dished pistons) will give you 10.2:1 compression ratio.

The higher the compression and more radical the cams are, the lower the mileage before it needs work no matter how big (CI) the engine is.

What are the numbers for a 124" Hot Set Up Kit using 640 cams @ 10.8:1? No head porting, using supplied gaskets.

Very true. My 107 has the 10.5 compression and I like it....wouldn't want anything higher. Honestly, the 124 LC has always had my eye.....

Well, it's like this! Those of us with that performance level know we cheaped out and we wouldn't want you to do the same, then bust us for not telling ya to go the whole hog!

With their 66mm Throttle Hog and a good pipe along with the 1.650" exhaust valve they now use, we are seeing/hearing 140 square.
At/near 150/150 if headwork/compression is introduced.

If the op is looking for 110/100 there are a few bolt in cams that could do the trick, cheap money...

I did the 107" in stages and eventually ended up with the 124" and 585 cams. Wish I went straight to the 124" from the start. More power than I even need and very reliable. Kirby built mine and I couldnt be happier with the results!

Cams are a gateway drug
