They work great.

Sounds good, Scott!

The only idle I want is the idle the cam wants.

Had a 09 RK Classic with 103 and 551 easy starts loved it just did the same to my new FLHTC and went with the new 557 cam which is built for the Tri-Glide and very impressed its not a hot-rod but it gets up and boogies with the 110s and its a heavy Bike.
This time I went with the gear drive kit works a lot better.
98 hp and 113 ft./lb. not bad for a Bagger.
one slight negative is you cant do a compression check with the easy start if you need to .
Never had any problem with the idle I've got min set at 940 sounds sweet

Regardless of whether you use ez start cams or compression releases, you are still limited on the amount of corrected compression that you can build into the engine. That is the real question.

I was wondering about the EZ start cams when I did my build. I got conflicting opinions locally and ended up doing a standard S&S 570 with compression releases. It means a lot to see Kirby, Scott, and others say how well they work. Might go that direction with my next build...

I got the ez starts and Hillside build with a couple of trophies on the shelf.

Hillside 107
Stage IV heads
585 EZ starts
HPI 55/58
D&D Fatcat

Made 124/121, it's a very nice running set up and never had a problem with the ez starts.
