Ok i knew the o 2 sensors changed and they went with the bigger engine but i didnt know they went from Delphi ECM to Bosch! I got a 2012 Fatboy Lo and cant get crap for it right now!! Everyones gotta change the exhuast and the friggin Tuners! So why the switch from Delphi to Bosch??

 

I didn't know they did that (The sportys stayed Delphi), but Bosch makes an OUTSTANDING ECU.

 

Ya i didnt know they did that either till i talked with Vance & Hines on the phone today! Thats the main resean why all these companys have to change there tunners for the big V-twins because of the new ECM and their exhuast because of the new 02 sensors! Looks like my 2012 Fatboy Lo will be stock for awhile!!! Unless i go with the rush slip ons!

 

Our slip-ons will fit the 2012. We have to make changes to every single full exhaust system we have, as does every other manufacturer. All of the fuel management manufacturers are working hard to get the 2012 versions on the market.

 

You can do like I did. Get the HD download until the fuel managment systems come out. I got the HD Fatshotz slip ons

 

There are a few who are taking the O2 sensor bungs and cutting them out of the factory pipes and installing them in the pipes they want for their bikes, the only thing to watch for is the placement of them in the aftermarket pipe, it has to be real close to where they were removed from (location that is). Of course you need to plug the existing bung with a plug.

So it can be done, it just costs a little more. Unless you have the equipment to cut and weld.

 

I saw on v&h website the other day that now have the big radius 2-2 for a 2012 fxdwg103
