Hi all, I have two questions about the dtt install, 1st one - is drilling out the brass washers on the tps enough room for adjustment or will I need to ream the holes more. Next, when hooking up the interface , it has a switch for 88 & 88a, I have an 04 ultra and am not sure witch one to use. I know this thread should go in the efi section, but alot of you have baggers and will probably be able to answer this as more read this section, I know I do. Thanks in advance.

 

ream em and save yourself havin to do it later....88a

 

Thanks man. I'll be back for more info after I get my heads done by HQ. Already got the 575 cams from doug installed, so scooter is down until then. I would appreciate any advice on tuning the dtt, I have the 113 ci hd cylinders and hd pistons-flat top. Thanks again for any suggestions on dtt tuning when I get this booger back together. It's sitting in my garage and looking pretty sad with all the parts congregating around it waiting for heads.

 

Cool.... Keep us posted!

Have you already had the cases bored?

btw - ditto bryan's answers to your questions....

 

Hi Phil, yeh, bryan's answers were the ones that i needed to get started. I feel like I know you both as I have been reading your posts on the dtt install a while back. My eyes have finally healed from some of those pic's! I had the cases bored and se 4.060cylinders, flattop pistons installed back in february. At that time I could only get the big job done. I had to wait to later for cams and heads.I originally was going with hd se heads and bigger cam (I already had se203's in when I was only going 95"). But then started reading more & more about afthermarket part suppliers and I,m glad I did . Waiting for doug @ headquarterd to return my call now for head selection as I write. I,m trying to as much of the work as I can , Not so much for money savings but for the knowledge of knowing my bike better. Of course the money savings will be welcome also (assuming I don' screw things up!) I ,m sure I will be calling on you guys later for more dtt info.. thanks inadvance for your help. Tim

 

I just punched the brass shims out with a small screwdriver and a block of wood and that gave me more than enough room to set the tps.Of course,I cracked mine but it still worked.

Tough crowd today! So I will ask this question with thick skin.Does the 113" use the stroker crank which is about 1000 bucks? And if I didn't stroke it would that make it 105" motor?

 

Yes it does, but I don't think I paid that much for mine. I believe hd makes two cranks- one standard and one heavy duty. I chose the standard, like the one's in the 07's. I don't plan on doing heavy duty launches since it is a bagger, just want to be able to have a llittle fun when I crank it on, plus I normally ride 2 up and in the bee-uuu tii full blue ridge parkway. Some of the little moutains have some pretty good hills and the guys I normally ride with think they are riding crouch rockets! These guys are riding ultra's and are in late 50's and 60's. They can do things w/ an ultra that scare the s--t out of me and my wife. I like to see some of the country side, so I'll catch 'em on the straights.!!

 

If You bore it it will be a 95" and if you stroke it,it will be a 103"

I used the Screaming Eagle crank and pistons to stroke mine.I don't remember exactly what it cost for parts (around $1300.00 I think).
