lets start by saying I have searched and searched, but can someone please help compare the tw 555, tw 777, tw-7h, cr575. I am new to the whole cam thing; however I want a bolt-in application. running a thunder max with dragos 2 into 1. Im looking for low to mid range power. Thank you for the help and sorry for the novice question. Its hard to find information specific to the 110" and then it is vague at best

The intake closing number dictates the compression needs of the particular cam.
We set the Wood 777 at 10.45 for pump-gas friendly power, for instance.
Your 110" heads re-worked, with some t/body work, along with the 777 has shown 116/125.:)

OK...first, you have a great cam (SE255) in your 110 from the factory for low end to mid range power...the problem with that cam is that it generates heat and drops off approximately 3800 rpm's...you could stay with that cam and do some headwork and you would be suprised how well that stock cam would run!

However, if you just want a bolt in at this stage without messing with the heads/compression/gasket changes etc., I would go with the Cycle Rama 575 cam...works great in the 110 and can grow with you "if" you decide to go to the next level. Quiet, less heat, low to midrange power, and has usable power from 1400 RPMs to 5000 (well, that upper RPM level is as far as I take my Harley). Downside to the CR575 cam: Rear tire mileage is terrible! :)


I have used various Woods cams in the past as well, but I find that they do need compression/headwork to really work well (and can be a bit "noisy"), but other people will differ and love them.

One other thing, if your going into your cam chest, change the bearings, lifters, and you will need adjustable pushrods...I also changed the adjusters to the Zippers Dual Piston Cam Chain Tensioners...looks like a quality product.

Lots of options and opinions so good luck with your choice.

Thank you so much for the help. There is so much information and I can't take it in fast enough.

Go to the Fuel Moto site and look at there dyno runs with the different cams and exhaust. The woods 222 made 105 hp and 118 tq. The 7h made 110 hp 118 tq. Fuel Moto's service is top notch too!

I have the '13 CVO RG 110". It is getting head work done from TMan right now. Projected torque curve staying with the 255 SE cams is from 2,000-4,500+ rpm. Doc is doing the tuning and build once it come back from TMan (supposedly tomorrow). I should have my scooter back the first part of next week and I will post the dyno results. I have the TTS tuner and Fat Cats 2 into 1 big bore pipes. Hoping to get 120+ torque numbers.

What lifters do you like?

I have the CR575 cams in my CVO 110 and it runs great. (I do have to get a new tire this spring :)
I re-used the stock push rods with no problems.
If your going to replace the lifters I think I would go with S&S
Though I have heard the (NEW) just came out this year> Screaming Eagle lifters are working out very well also.

S&S lifters are what we favor here.
Another fantastic, overlooked cam, is an S&S .570.
In the 10.0 cr catagory, I do not know of a cam that'll stand toe to toe with it.
With it's exhaust timing, it shed's a ton of heat.:)

IMO unless you are willing to open the engine up to add compression, I'd tend to leave the 255's in place.
Getting rid of the Cat and a proper tune would be higher on my list of things to do.

Current cam on the "guys in the know" "A" list is the Wild Things TC24D.
Me I don't have a paddle in the water and I can get most of them to work well just the treatment and cost is different to arrive there.
If it was me and I owned a 110 stock and I was relegated to use the TC24d I would advance it 4 and use a 1.725 rocker on the intake. Same treatment for the Andrews 54h. The 110 is a different animal by virtue of the heads not so much the displacement and what works for a 103 may not work the same with the 110. The 110 will be much more pipe dependent too as the overlap increases. This means pipe will work really well or really poor as opposed to mediocre with the OEM headed motor. Just my 2c

I was just talking to frank at dragos about this he was saying the best cam to run for app is a TMan 600.

I have been talking with Doug at headquarters and he stated "the stock 110 heads are terrible with their huge low velocity ports. The 500 cam helps the problem and the 575 compounds it." I am really leaning towards this cam it, it seems comparable to the tman 555 torqster.
