SHRADER  The rockers are non adjustable but the adjustable pushrods are not. When I do a cam change the pushrods get changed! No if and or buts. The cost is only 120.00. When you spend the kind of money that was spent to do the upgrades that little bit more won't hurt. I also never run stock lifters with a cam change. Stock lifters are just that STOCK. With the extra pressures from the valve springs and the high lift of the cam I personally think they will not open the valve as they were designed to. Also the perfect fit pushrods are designed for certain cams and springs and heads that harley sells. I'm sure they can be used for other applications but I am not ready to experiment with them!

Hence lesson four: You can take a stock lifter and disassemble it and add travel limiters for about 12 dollars. When you do this adjusting the valves takes on a whole new perspective. If you use you stock pushrods or even perfect fit it you will listen to a lot of valve train noise. that is where your adjustable pushrods come in.If you use an aftermarket lifter they have a certain number of FLATS after all lash is taken out for them to be properly adjusted! It really is not that hard but worth the extra H/P and torq.

Yes I have a different throttle body. I have not installed it as of yet. I might get around to it today. It is a Zippers 50mm throttle body. When installed you need to do an ECM update. I purchased a Zippers Thunder heart ECM last week(which you don't have too buy). They have already preprogramed it for my setup with a base map. I have the program to make changes when I get the bike back on the dyno. The new ECM can do a lot more than the stock harley unit with a power commander or the race tuner. They are doing a lot of R&D with the unit right now. They tell me the throttle response is a lot smoother and more responsive. I will let eveyone know how it works. Stay safe.

Harley Davidson P/N 27615.00 pro 43mm EFI Induction Module Kit So they do make it. I will check the parts catalog tomorrow on the stock part number on the SEEG and the Ultra Glide Models.

Now you missed my point on adjustables I never said they were junk I said the perfect fit IMHO were junk! I love adjustables and will use nothing but once I go into the valve train on any of my motors.  Yes you are correct you want to be a light as you can and retain the correct geomentry(sorry for the spelling)

Adjusting stock lifters would depend on the pushrods you are using. IE fine thread or coarse thread. So the number of flats will be different on different models. Rule of thumb would be to take out all of your lash and then go .100 of an inch more. So you need to measure how many flats that would be on your pushrods. I hope this helps you.

THEREENTH ENDETH LESSON THREE!!!!!

Has anyone changed the pistons on their 103" to increase the compression. One of my local HD stealers tells me that HD makes pistons to match the low compression stock heads on my SEEG and the other dealer says that HD says the stock heads won't work with more compression. I'm trying to get the potential out of this motor and can't get the same recommendation from any two people. Any suggestions are welcome.

Opee

I've read this thread and don't believe anyone has answered Opee's origininal question.
As of this writing H-D does not make a piston that is compatable with the stock SE103 heads that will increase the stock compression ratio.PERIOD

I know that but you said they don't make one!!!!! So I gave you a part number!

If you read back somewhere I did post part numbers for pistons to increase the 103 motor to 10.5 to 1 uncorrected. The numbers are as follows standard bore 22483-04 plus .005 22484-04 plus .010 22485-04. So we now have an answer for OPEE. They better be the right ones because I have a set setting in my shop waiting till after Myrtle to install them!

I was under the myth that the SEEG had a different throttle body if I am wrong I stand corrected. All I do know is mine has a Zippers 50mm throttle body. I did make a call today to see what size the standard throttle was and the guru did not know but would check and let me know tomorrow. It is either 38mm or 40mm. I still thought the SE models had a larger bore but if I am wrong it isn't the first time and I am sure it won't be the last! Stay safe.

Here I go!

Have to give this one to Shrader.

DAWG, on your reply # 19 you said "the throttle body on our SEEG is Harley's 43mm,,,etc.

After reading Shraders post I whipped out the S/E catalog.

Page 29 item B,  Part # 27615-00  Screaming Eagle Pro 43mm EFI induction module kit.
It states " This larger bore (43mm versus 38mm stock), etc.
Also is listed for just use on 99-01 Twin Cam

No lesson here, I just appreciate the knowledge and experience both you and Shrader bring to the site.

And "Tater" see if you can get me a spot in that "How to win Friends and influence people class"

Hd you are correct Shrader told me that the motor company didn't make one . I just simply replied that they did. I knew it was a replacement for the M&M fuel injection but he asked. I was and I still am under the impression the the SEEG has a larger throttle body. I might be wrong and I am going to check tomorrow. I have a service manuel for the SEEG but not a parts manuel. I think the dealer told me that it was a different throttle body. I will post the results tomorrow. I do know you can get the factory throttle body bored out as I do have one I was going to use, but went with the Zippers 50mm throttle body instead.

Shrader I did check the parts book and those part numbers I posted  for the pistons are good numbers.Stay safe

See post number 25!!!! Those are good numbers.

Page 46 in the Harley go fast parts catalog under "B"These big bore pistons feature a unique dome shape that is matched to the SCREAMIN EAGLE 103 cylinder heads to maximize horsepower output!

Hey DAWG

Let us know about that throttle body inquiry!

I would like to know what size the one is on my 103.

Shrader?? you know? [smiley=nixweiss.gif]

And as for the adjustable pushrods. I have them in mine, but you talk like they are junk
when anybody who knows anything about motors will tell you that the lighter you can make the valve train components, while maintaining the appropriate strength, the better it will be. All I'm saying is that there are pushrods available for specific applications using specific SE components that are a viable alternative to adjustable pushrods.

Now HOW DO YOU SET THE VALVE LASH ON A STOCK ENGINE?

THEREETH ENDETH LESSON ??

SHRADER

I GUESS YOU NEED TO LOOK BACK AT REPLIES 17,28,30 Read very carefully there was never anything said about adjustables being junk!!!!!

NOW ISN'T THIS FUN AND WHERE IS THE KING WHEN YOU NEED HIM??

Hey Dawg, your cool, just keep on with the info! [smiley=xyxthumbs.gif]

But on another note,,

I remember someone quoting something somewhere from Rodney King. [smiley=laugh.gif]
