Does anyone know what instructions I need for the dobeck tfi? They have a ton listed on their website for download. I have a slight stumble at cruise around 3k rpms and want to see if I can tune it out. First i'll change the plugs though.

Here's were it was set when I bought the bike. the last one is set at 7. The bike has a drummer, open airbox, might have race filter, but not a K&N, race ecm.

I think I found it on their site under harley instructions, understanding the pots.

here's the final settings I ran when the TFi was installed...

K&N
stock inner airbox
no snorkel
Race ECM
Drummer pipe
TFi settings = 4 – 7:30 – 6 – 8:15

EDIT: this was for an earlier generation TFi, around '05-'06, i believe they changed a bit but if yours is from that gen you could give the settings a try

the stumble is from too much fuel....turn the second pot counterclockwise to the 1oclock pos and the 3rd also, leave the 1st alone and put the 4th on 8oclock....this is for an xb9 only...

Well the 3rd is already at 1, but i'll try the second at 1 and i'd already planned to set the fourth to 8 after doing some research at dobeck forums.
