Topic: STOCK STROKER 103 VERSES STOCK TWIN CAM 88 (Read 16230 times)

bruz · « **on:** March 31, 2005, 07:11:56 AM »

I would like to know exactly what engine components such as pistons,rings,heads,valves,cams,camshaft any other item, the hd part numbers that set the two engines apart in the efi 88 and 103. What would have to be changed in an 88 to make it a 103 and what would it cost? How much more power,hp ,torque etc. does the 103 have over the twin cam 88? Are the gears in the transmissions the same? At 3,000 rpm's how fast is the 88 and the 103? What exactly does stroker mean and why does it have a different sound than the 88? If any body will help me with some answers I will be much oblized.

i went with the se-103 kit right out the box.
the gear ratio is the same.the tranny is the same. the kit comes with a heavy clutch spring.
stroker is the flywheel which gives the motor a longer stroke. hense a larger displacement.(1690)
i can't tell you how fast i am going at 3000 rpm's because i don't have a tach.
i can tell you that i an going much faster than a stock tc88.
if you check out this link, it list most of the components. http://www.harley-davidson.com/gma/gma_product.jsp?PRODUCT%3C%3Eprd_id=845524448764975&FOLDER%3C%3Efolder_id=2534374302319503&ASSORTMENT%3C%3East_id=2534374302319503&bmUID=1112276123433&bmLocale=en_US

Bruz,

Sorry I am not much into part numbers until I really have to do something, but when you take a 88 inch motor and go to a 103 motor there are complete kits from the SE catalog.

somthing has to give with this weather.
some of the chit we talk about is just way too ridiculous.
it's time to RIDE!!!!
the forum helps to get through the winter, but enough is enough.

Yeah, 'er 'uh, kng103,
I like ridiculous, Hell, I am ridiculous! [smiley=huepfenjump3.gif] I don't know how they teach Math in NY, [smiley=nixweiss.gif] but down here in the Mountain State, they taught us if you have the same tranny, the same ratio, and the same RPM, Cubic Inch Displacement would not be a factor. [smiley=laugh.gif] You would be traveling at the same rate of speed, regardless of power supply, which I would estimate to be 70 MPH @ 3000 RPM. There endeth the lesson. Later--HUBBARD

your theory is only correct if both bikes are in 5th gear cruising.
wouldn't a bike that has 20#'s more of torque, get to that rpm much faster?

Same sprockets, tranny etc....basically, same final drive ratio...your rpms and speed should match. You may get there quicker (3000 rpms) but once there...they should be the same.

You change a sprocket, gear or soething like that, then yes, your rps could be different.

Like I said, when we go to the Dragon last man to the top buys the other a shirt.

Have you seen the T-shirt on John Kerry?
"I spent 10 million on the election and all I got was this lousy T-shirt"

Got a T-shirt for you Tater. On the front it says,
"I spent 60K on this Lead Sled and didn't even get a shirt from Deals Gap"

[smiley=xyxthumbs.gif]
"Tater" you are so easy!

Also on the back it reads,

"Someday, I will be like my friends and own a CVO"

If the estimate of 3000 RPM = approx. 70 MPH, then what RPM would approx. 115 MPH? [smiley=nixweiss.gif]

Yeah, 'er 'uh spydglide,
If my memory serves me right, that was 5200 RPM in fifth gear, with 25 tooth engine sprocket, and 36 tooth clutch hub sprocket. I could be wrong, [smiley=nixweiss.gif] but I will tell you definite, when I bust hd2003's a-- in the Valley!! [smiley=huepfenlol2.gif] Later--HUBBARD

Now that we have collectively imparted to kng103 some of his shortcomings in the scope of the 3 R's, would you kindly elaborate, from your vast wealth of knowledge in these matters, as to why a flywheel does not a Stroker make? I trust you to complete this lesson post haste, as the Class is prepared to move on to the next session. Later--HUBBARD

wonder why the motor needs a stroker flywheel to bring up the displacement?
wonder why hd calls it a stroker flywheel.

It's

Bore X Bore X Stroke X # of cylinders X .7854

Works everytime! [smiley=xyxthumbs.gif]

hd2003-se2005 · « **Reply #28 on:** April 02, 2005, 08:35:04 PM »

Both KNG and Hubbard are right!

They have both said the same thing in two different ways.

Power (quality bore and stroke) will get you acceleration!
If gearing is the same then speed will be the same!
More power will only get you more acceleration.

I always thought stroke was the "distance" the piston travelled...Bore, the diameter of the piston. Now, to calculate the displacement you multiply the stroke by the area of the piston (Pi times Diameter) then times the number of cylinders.

so, for the 103, Bore x Stroke=3.87 in. x 4.37 in.

so, (3.14)(3.87)(4.37)(2)=106.2 Doh! [smiley=confused5.gif]

Proof that Alcohol impairs judgement...

Pi(D) is circumference...not area...thanks for correcting me!

(3.14)(1.935)(1.935)(4.37)(2)=102.8
