Cyclerama 575 cams/formal introduction
As the tittle says I have a dyno chart to share with the forum for anyone curious about CR575 cams and also like to introduce myself to the forum. I have been lurking around here for about two months now and want to thank everyone for answering all of my questions and PM's. This forum is a wealth of information for someone new the Harleys! This is my first Harley and althoug not impressed at all with it in stock form I love it now that I have done the mods to it.
On to the cams. I couldn't find any information in the touring forum so here it is. I was hoping for at least 100 hp but fell a few ponies short. The bike only has 550 miles on it as of yet, so it might gain the few ponies I am looking for as I log more miles.The torque is great at 113. It peaks at about 4k rpm which depending on your riding style could be good or bad. The area under the curve is very broad and usable. I wish I had done the 107" piston/jugs at the same time. Oh well, winter is right around the corner! Feel free to critique the the dyno chart/compare to andrews or woods. Also I haven't picked it up yet but I'm sure it is a blast!

that looks good , I love mine too , the thing I like on your curve and these cams is you get to 100 torque at 2500 rpm's , most of my riding is between 2500 - 3300 rpm's so the cams keep you right there , you curve look close to mine good job
Yes the heads are stock. At this point I'm done with motor mods. I wonder how many people have said that!
Great result, looks like a proper tune. It's hard to break 100 hp without bumping compression and doing a little head work. 95 hp in a cammed 103 with stock heads is a realistic goal. Pull the heads, blueprint the combustion chambers and run a thinner head gasket and you'd be there.
