After my 1000mile service I ordered V&H TD's, Fuel Pack and KN filter to reduce the heat problem, I kept the stock mufflers. I noticed on my way home that temperatures were a little hotter and the performance wasn't as nifty. Where before when I opened the throttle I needed the seat to stop me being left behind but now it just pulls away. I thought at first that was because of the free flow with the V&H TD but when I got home to my reading glasses, I noticed on my paperwork the dealer had fitted; 1584 St 1 EFI Kit and I don't think they fitted the KN filter.
Has anyone this set-up and does the KN fit with he St 1 EFI Kit and why is there less power now than with stock.
