88" to 95" setup... confused.
Hello everyone,
Not sure if this belongs in the tech forum or not, but here goes. So I have a carbed '04 Dyna Low Rider, and I want to hop the motor up. I spoke to a local dealer and here's what they proposed:
I am also talking to Gregg Klopp at Pro Performance, here in MN, and am getting a quote from his as well for a 95" build. I hear he is really great, but he is a bit more expensive. However he isn't limited to Harley parts, so I probably have more options with him.
Looking for opinions on the dealer proposed setup... as well as your thoughts on dealer builds vs. going to someone else.
I am looking for a reliable, but hopped up 95" setup. I don't need the fastest bike in the world, but I would like something with quite a bit more zing.
Thanks!

- SE Pro Super Bore 42mm carb
- SE Pro Intake manifold
- 95" cylinder kit
- Pro Twin Cam forged high compression pistons
- Compression releases
- SE 257 cams
- SE Perfect Fit Pushrods
- Hydraulic Cam chain tensioner & high flow Oil kit

I did almost same as you i have a fuel inj, i did all above ex i used bob woods t6 cams and run just over 10.4 comp, i did the pressure realeases, ect but used the se adj pushrods, and the same pistons and of course you change the springs at that point i also did the hydrolic cam and oil pump upgrade, bike runs like a bat out of hell i diden`t want to go to crazy wanted go keep it reliable and believe me it is

How about going on Ebay and picking up a set of '06 take off heads, a used 2 into 1 exhaust, a set of 203 or 204 cams, rejet your existing carb, bore out your cylinders, and pick up a set of cast 95 cu inch pistons?. That should get you started and if in the future you need more, at least your at 95 cu in already.,,

First off, if I were planning some engine mods like you are, I'd be doing the work myself so I wouldn't be looking for a shop or dealer. But that said, if I were in your shoes, located in MN, I'd consider taking the bike to FuelMoto in WI. Talk to them, it might be worth the trip.

The more I research, the more confused I get, gear driven vs. chain driven cams, all the different heads and head work, cam designs, clearances, the list goes on and on. The more I read, the more I realize I how little I know.

I'm using Wood Performance TW-6HG cams which have a .590 lift and I'm using the stock heads.
My engine builder did use heavier springs and did a minor amount of machining in the rocker tray area for clearance of the springs. And the rocker box covers may require machining of some of the webbing on the underside for clearance.
I doubt your compression actually ends up at 10.5:1. Most of the Harley claims about combinations of cam, heads, etc. and the resultant CR are a little inflated.
I'd ask about the springs again, but every thing else they're proposing looks pretty sound. The only thing I would recommend adding is a programmable ignition similar to the Crane Fireball Hi-4TC. It will give them some flexibility with regards to setting the initial advance, slope of the ignition curve, and the offset of the rear cylinder.
Other than that, I think you'll be very happy with the results compared to the stock TC-88. It's really about the best bang for the buck you can do.

"Reliable, but hopped up 95" set up" could mean a lot of things to a lot of people. On the low ( cheap!) end, the biggest bang for the least bucks which will give you 80 % of the power for half their quoted cost:
95" cast ( 9.5 to 1.) S/E pistons using YOUR cylinders.
42 Mikuni with your stock intake, ( S/E intake is useless w/o flowed heads.)
NO compression releases.
Adjustable pushrods
Andrews 26 chain drive cams, ( or HD similar,) with S/E Hydraulic tensioners and oil pump kit.
You'll push 85- 90 HP, ( easily 20 more than you've got now,) have GREAT torque,
and can run premium gas from virtually any station (91,92,93 octane.)
On a bike as light as a Lowrider, you'll think you're flying.
There are a ton of more experienced guys here that can get you over 100 hp in a blink, but it will cost a ton more. It all depends as to what you want.

I would like a build that woops a stock fuel injected 96" or 103", or at least keeps up with them. I don't need the fastest bike, but one that can startle me a little at first, and make me smile when I crank open the throttle. I would be happy with 90-95 hp, around 100tq I think. But I also want something I can ride every day without having it in the shop all the time to be fixed. Would I like a 100+ hp bike? Sure, but I want to be in that zone of really fun performance, with decent reliability.

My 12 year old Dresser has the kit I just described but with MM fuel injection, (which for motor building sucks
,) and with 850 lbs of bike with 100,000 miles on it will walk away from a Stage 1 103 let alone stock one. And you're 200 lbs lighter than my bike.
I had a hunch about what you were looking for. I'd reduce those expensive wish lists a little bit.

You just want to 'woop' on a stock 96/103? I've already suggested too much power then!
