Hi all. As I mentioned in one of my previous posts, I'm having a change round of my 96in Fatty. The V&H Grenades are going. (Just to give my ears a rest) and I want to replace them with the standard Fat Bob system. Couple of minor issues that I would appreciate some advice on.
1/ Probably the most important question. I have found a virtually mint condition blemish free 103 Fat Bob complete system.... Will it fit dimensions wise? I've had a look at the H-D parts lists and the part numbers for the headers are different, everything else is the same.
2/ The 103 system has the exhaust valve. My bike is a US market model and doesn't! Is the default position for the valve open or closed? Will I have to resort to some form of bodgery... Sorry I meant engineering process to either remove or hold it open? (There may be wiring in place to fit the servo but I don't know if the ECU's are different).
3/ I have O2 eliminators fitted with the V&H, the 103 system comes with O2 sensors. Will the plugs match up? The part numbers for the sensors are different. Is there any benefit to keeping the O2 sensors blanked off with the standard system?
4/ I've also found a half decent 96in system, it needs a coat of TLC but is sound and fairly presentable as it is, Would I be better fitting that?
Finally are there any pitfalls in doing this swap that I may have overlooked? Incidentally I will also be doing a cat delete.
Thanks in advance for any help you can give me.
