Just went for the first ride with my new SPOs. Great noise but maybe the idea that they might be acceptable to the neighbours for my 5am starts was a bit optimistic....

Anyway, that apart, the bike wasn't right. I have a PCIII fitted with the 'standard' upgrademap for my 07 ultra, standard pipes, air cleaner, and ecu - O2 sensors disconnected.

It felt that the motor was out of balance somehow and it clicked like crazy when I parked up which it has not done before.

I am going to try the vance and hines ovals map next but wonderd whether I might be doing any damage along the way?

Thanks in advance,

Pete

 

I had SPO'S on my ultra until I went bigger,I did notice a lack a backpressure with them so you need to add more fuel I would think. I had the clicking sound also I think its the mufflers expanding and contracting.
