No problem getting those 110's into the mid-120's.Torn between stage 4 HD kit or going with gear driven cams, high compression pistons, crank work and larger throttle body. Anyone have any experience knowing which gives best performance without sacrificing reliability?
The 110"ers are 9.2 cr.Thanks for all the suggestions. I think the stock pistons are 9.6:1. With head work and S&S cams, do you think the S&S 583 cams will give me the best low to mid range torque as that is what I'm after? Maybe the 10:1 or 10.5:1 pistons would give me more performance but will I sacrifice reliability? As I review the S&S dyno chart, the 583 cams seem to pull strongest from 2,000-4,500 rpm. Also, would you have crank work done while its taken apart? Should I go to a larger throttle body as well? I really want to do this right the first time. My old '02 Roadking I punched out to 96" with pistons, heads and cams and it far outperformed my stock CVO Fatboy 103" but it took a few trial and error attempts and cost me a ton.
I posted this same message on the HDForum.Why even mess with a 110".There's a sponsor on here claiming 129/134 out of a 107". I have a beach front home in Arizona for sale if anyone is interested too.
Not givin ya a hard time but I rode the 107 also ~ Yep I live in FL but have been to the sponsors shop twice in the last six years ~ yep I rode mine there ~ first time during the 105th and second time 2 years ago ~ He worked both of my bikes ~ not crazy numbers just solid performance, ridable and dependable.... In addition I too rode the 107 ~ not sure about the numbers but can tell you that at 70mph the rear end broke loose I rode it for about 30 miles & was thoroughly impressed ~ not designed to be a forever motor ~ I have nothin to gain by posting this just choose to spend my money with him ~ The numbers on my 103 were 110/114 and verified by another shop. 555's and type b heads ~ bump the compression with a head gasket... Above are the numbers and specs on my current CVO RG ~ the numbers have been confirmed by two shops ~ that one was done by the HD shop ~ numbers came up about 7% or so just by going to his head (from true duals).Why even mess with a 110".There's a sponsor on here claiming 129/134 out of a 107".

Kevin, I remember you and I know you are a close friend of Frank's, he does your work, and you use his dyno now that he has one, and that's cool. However you also have a history on this forum of discrediting other peoples work for some reason, that is not cool. As far as your dyno charts I could get into the physics and strategies on how a dyno works, or how conditions, engine temp, or what can change one dyno to another but in the end it doesnt take a rocket scientist to see whats going on here. You could not make your agenda more clear, simply take a look back at the posts you have made. So lets see the charts and the documentation showing the differences between dyno runs and we can put everything on the table for interpretation. I would be very interested in seeing any charts and supportive data from other dyno's since "everytime I dyno it after I leave your shop there's a 10hp difference" These comparisons need to be direct comparisons as well, same components and within a specific window of when we tested your bike here. Last I remember when your bike was here it was 180 or so HP, if you made runs on a different dyno making 10 or so HP less thats only about a 6% variance which is absolutely possible and normal based on conditions alone, let alone many other factors. A dyno uses simple laws of physics.There's no conspiracy here no drama just my opinion.I think your Dyno numbers are bogus.You have tuned my bikes several times.You know me my name is Kevin.I'm sure every dyno is different but everytime I dyno it after I leave your shop there's a 10hp difference.Thats been at two different Dyno's three different times.So no I dont believe your numbers I do think your a decent tuner but I also think your a Master Manipulator of the Dyno.Again that's just my opinion.
