who all has one of these kits on your dyna. I am looking for a setup with lots of torque. I do not wind my motor very hard so the torque needs to come in at around 2500rpm to 3500rpm or so. I have asked local shops and everybody has a different answer about what types of cams, exhaust and so forth. So i thought i would drop in and ask for advice. Thanks alot.

 

Been pondering this one myself lately. The 98 inch kit from GMR performance sounds great, you can find info on this site by searching which you probably have already done. With my recent experience I'd say do your homework and research on what will be the best kit for you, and as far as the dealer service deptartments go just find one that does the highest quality work and don't worry which one knows the most about which kit to buy. I'd rather have quality work done with an average kit than bad work done on a great kit. My opinion would be to look for one with a larger bore as opposed to a longer stroke. A slightly larger bore will have better longevity over a longer stroke due to keeping the same piston speeds, etc. I like S&S's 100" kit, but it's pricey! If you pay for a larger bore up front you can always increase the stroke for cheap later. Don't forget to save money for your new oil cooler.

 

Hi,

There are two ways of looking at this, cost and performance.

Cost wise, the 95 kit is the way to go. You can have your existing cylinders line bored, and just buy pistons, rings and a gasket kit. Can also have the heads ported while it's apart.

The 98 kit is an expensive way to do it in comparison. While you might gain a little more power initially, this can be overcome by using the difference in cost to do some nice cam upgrades and larger valves with the 95 kit using your original parts, with a choice of flat-top or domed pistons, etc.

My opinion,~go 95 using your heads and cylinders, flat-top pistons with Cometic head gaskets, and use the difference in money to go with a gear driven cam setup(S&S 510G), ported heads(see our sponsor's website), leave the valve sizes alone, and DYNO tune with either a power commander and Stage I download for the higher redline, or go with the SERT on a DYNO.

might also want to think about getting your parts diamond cut on the fins, as it really looks sharp!

Travler, I'm a lot confused. I have a stage one, screaming eagle air filter and Vance and hines Big shots staggered and Vance and hines fuel pump. The fuel pump instructions said don't do the HD mapping just do the fuel pump mapping. although I got a chart that showed the settings if you had HD do their mapping and you used the fuel pump. I had it done by the HD dealer per the V&H instructions. Plus they took off the black round can on the front of the bike. The tecknition said it did change the RPM limiter, but I really don't know, I've hit the limit I think it was somewhere between 5800 and 6200 but I will check again when I ride, next.

anyway, I want more low end torque. I was thinking about getting the Stage two. The dealer said the best setup would be with the screaming eagle head and they said something about domed pistons. And I think Stage two also includes changing the cams, but I'm not sure about that.

basically I said if I do this I want the best setup.

I don't really know what the CI would be when they do this. I knowthe cost was abig number somewhere between $2200 and $3,200 - I think $2,500 sorry I can't remember.

In what you wrote I wasn't sure if you do the 98 Kit and the other things you said you would do to the 95 kit then would 98 plus those other thingsbe even better than the 95 kit with those things?

Also, I love the sound of my bike, will the sound change when I do the stage 2? I'm okay with deeper, I don't like tinny or higher pitch. And yes it pops when slowing down when I don't down shift sometimes (more in the cold mornings) but I like that sound. LOL.

Will I have more concerns about the bike breaking down if I do a stage two with screaming eagle than just leaving it as it is? Or I should be okay with my 7 year warrenty?

Lastly I keep hearing they are going to smog bikes soon, Will I ever have to have my bike smogged in california and would doing the stage 2 make it so I couldn't register it or sell it? I have heard some guys say if they inact laws for smogging it could never affect 06 bikes but if they do it now it could affect 07 bikes. Probably if they wanted to smog mine now it wouldn't pass due to the changes, but whats done is done and the rode back is short.

Assuming you say I should'nt have maintenance or breakdown concerns or smogging concerns or warrenty concerns. What would you suggest as the ultimate setup that would be in the $3500 or less range that I could have done by a shop and maintain my warrenty and if one setup leans more towards giving more low end torque and one gives more top end Horsepower, I would like the setup with more low end torque.

I will really appreciate your input.

Thank you.

I just started my Dyna last night, I installed a HQ 95 kit with there ported OE heads and the .575 lift GD cams. this thing is going to be a monster!

for more torque you need a little more compresion and some extra cubes.

On a Dyna I think 95 is plenty with some head work. If I had a bagger and rode 2 up, id to the 98 or larger.

 

it all comes down to money. i put a 95" on my 06 wideglide with hi comp pistions and a hi lift cam and some head work and i have max torque around 5k but it starts with 90 and only drops to 85 i will put one of my dyno runs on here to show you the curve to give you a something to go by

 

Mentor, I really don't know the lingo yet for things as deep as a stage two kit. Is HQ a brand of kit installed by Harley or 3rd parties or both? I think Ported OE heads means you had your Original equiment heads ported. If thats what you had done, does the dealer send them out and have them done for you? And do you tell them a certain way you want them ported or is there just one way when you tell them I want my heads ported. You said you have .575 lift GD Cams, Is GD a brand, and did you have lots of differnt choices in the size like .475 or .625 or is .575 the right ones for the porting you had done?

After youdid the upgrades (is this called a stage two?)does the bike vibrate more or less than the stock bike when stopped at a stoplightor when riding it and how did it affect the sound of your pipes.

Thanks alot. I really plan on doing the stage 2 (and it seems like there are differnent definitions of what a stage 2 consists of) on my bike so your answers really will help me learn enough to do it right the first time.

Thanks so much.

Macs,

I would be happy if I could get away with something in the range of $2,500 to $3,500. I want it to be all it can be but not if it makes the bike a worse ride from vibration or if it changes the sound from deep and wonderful to high pitched like a 4 cylinder rice burner, or causes it to leak oil prematurely and destroy the engine. Also it has to continue to be covered by the 7yr warranty I purchased. Hopefully you will see the posts from others giving me suggestions and I hope you guys will tell me what is the best for the money I can spend. And yes, I take women out on my bike most weekends cruising down the freeway at high speeds or through winding canyons. I would say our combined weight might be up to 400 (probabably 320 Lbs more likely.) I added most of the chrome covers and caps and other chrome pieces they have for my bike and a tach too. The last pieces were the chrome inner primary and base covers. I alsohave a big travel soft bag on the back and may get a pop on windshield for longer rides - so all this added some weight and wind resistance.

Thanks
JD

 

JD, I have been researching the engine upgrade for awhile.

I can answer a few of your ??s, but I am not an engine builder/tuner,
so I won't go very far in that direction other than to say look for
reliable word of mouth referrals, and read a lot here on this forum.

The 7 year warranty - keep your machine stock, or,
consultwith your dealer on this issue and how they will work with you.

I do believe HQ is referring to HeadQuarters.
They are spoken of very highly by the folks I know that are using their equiptment.

GD cams - gear driven cam set, as opposed to chain driven.
Pre 06 motors were poorly designed for the chain tensioners.
06 later are supposedly far superior. Time will tell.

Advantage of the GD is probably minimal on the 06 up.
That is debateable for sure. Cost of GD set is at least double.

stage two? - I think that means very different things to different folks.
The ScreaminEagle catalog defines the HD usage of the term.
I think. Maybe.

Yes, I used a Head-quarters 95 in Kit, they can be found at Head-quarters.com

i had to call and get a packaged set-up. the .575 lift gear drive cams use the S&S gear drive set that can be purchased from HQ or an S&S dealer. the pistons are made by C/P, very reputable!
they use your OE heads or you can Exchange if they have cores. I recomend sending your own.
they mostly use OE cylinders that they bore and match to the pistons.

I dont realy know what the stages are after stage 1, Ive never been found of stages.

Ive got a stage eleventeen head job and cams....huyk huyk

asfor the shakin......Hell ya it shakes! like a paint mixer at home Depot

And It sounds like a NHRA Pro Stocker!
