No throttle response.
I changed out the cams, lost oil pressure. Took it apart fixed problem with fuel pump. Now after putting all back I have good oil pressure no throttle response. When I try to rev it nothing idles nice but that's it. It's an 08 ultra! Any ideas would be appreciated. I'm thinking it's the O-ring on the pump but any other ideas would be checked.

Wow, I just wrote about mine going into limp mode. That is exactly what mine did. Will run about 20 MPH but no response on the throttle what so ever. It might be something different all together. What I am hearing is, it has to do with the TBW. Google TT418

Mine would idle but die if I cracked the throttle. They said it had low fuel pressure and when they went to change the fuel filter found the fuel pump top was warped. Told me it is common in hot climates

Going to check the pins. Does anyone know if the o-ring on fuel pump can cause this. I heard if it goes you get no rev because the fly wheel cavity will fills with oil. I changed it when I did cams wondering if I could have messed it up.

Do yourself a favor and hit it with contact cleaner and put dielectric grease on teh seals, I also spray wire dry on all connections especially the two TB cons, they have a SB out on this..
