    With the stock pipes, you may have to back down the settings just a bit or it may be too rich.

    I moved your post to the Dobeck section and they can give you the recommended changes with the stock mufflers.

    Dobeck 1250ST After watching you tube and reading as much as I could, Thanks to Randy Lewis, The Boss and Dallas from Dobeck I have read along with my almost 8 year old Grand daughter the very easy to read and understand install. As Smitty always says even a cave man can do it, I am now a believer. The only tricky part on a Dyna install IMO would be the lack of room to work, so removing the tank was way easier. I did use a bit of Dilectric grease on all the connectors to insure a water tight connection and ease in disconnecting if needed. I ride in the rain here in Florida so I don't want any surprises. I used double back tape to secure the unit to my tank panel for a test ride to dial it in setting at Green 3, yellow 330 red 330 and RPM staying at 4. I have Cycleshack turn outs with a K N filter. Running the same roads for two weeks I saw a major cooling of the rear cylinder while my mileage did not appear to go down yet. After test riding I mounted the unit under the seat and have no regrets other than I wish I did this sooner. Next I am going to play with the stock air box and open it up a bit now that I can adjust this TFI like adjusting a carbed bike, Capital Jack:s

    I have the 1250st and even though its not the gen 3 I run it with stage one suggested settings and it runs great. I am running HD stage 1 A/C and stock exhaust.

    recharge,
    Running the stock exhaust we would recommend to back off the Yellow and Red modes 0.5 a setting.

    Does this recommendation also apply to the 1250ST?

    IF it is running GREAT, Don't touch it BUT id you do???

    I think they will tell you to turn the yellow back a 1/2 number and the same on the green pot...

    I'd rather see you trim the green pot out by 1800 rpm and adjust to too much fuel than back-in to where it runs the smoothest and just a Tine bit more.. Good...

    Then looking at the finished number please(post it here) and I'd bet it will be a 1/2 number less than the starting suggested setting from Dobecks..:D

    My answer only.... wait for Dallas as His might see things differently..

    Yes, it is the same for the 1250ST. Running a stock exhaust compared to an aftermarket exhaust is usually only 0:30 different on the Yellow and either 0:30 to 1:00 on the Red. The stock exhaust obviously takes a little less fuel because it's not flowing as much air. Like Bubbie mentioned, we always recommend to start a little higher and then back off the settings depending how well the bike is performing.

    Just ordered my Gen3 today...(Thanks Dalles!!) and will be getting it Monday or so. I will be going from bone stock to a zippers Max-Flow (Thanks ctree!!) and for now stock exhaust but eventually to the ACE with open or midflow baffles (Love the stock look of the pipes). Not being a wrencher, I am looking forward to, and a little intimidated by this project. I am going to have fun learning though :bigsmiley11:. So If I understand what I have read on this thread, Stage 1 ac and stock exhaust...I will want my settings at G 3:30 Y 3:00 and R 3:00? Thanks.
