Well... I took my bike for its first run with the pod filters today (or I tried to).
The bike started easily, but as soon as I backed off throttle the engine stalled (going downhill). Every time I came to a stop the bike stalled. Once it was going it seemed ok, I only went to about 3500rpm in 2nd as I was only in the back streets around my home.
So now I have 3 options, 1-try to refit the original airbox with the engine in the bike (serious modifications will be needed), 2- remove engine and refit airbox, 3-buy power commander and get it dynotuned $$$$$...
No 1 it is going to be. I will update tomorrow with my progress, or lack of.
