Engine re map.

I use one of my own Bex Moto cans without the baffle on my 955i Speed Triple. I found a benefit from changing the Factory 10158 which I used with the TOR can to the 10158PK map with my can. The map is a tad richer and works better. Easily changed with the free TUNEECU software and an OBD2 cable from Lonetec.

 

Tunes or maps are free and can be downloaded from the TUNEECU site along with the free program on Windows (I paid a few quid for the Android version). You can purchase cheap OBD2 cables but your best going with a named brand like LONELEC

 

If you also go for a K&N filter this would also increase air flow through the engine, however, it would be a bit leaner.
So go for a dyno re-map and it would all be smoothed out.
I had the K&N filter and after market exhaust on my bike which made it run lean, the dyno run released 10% power and the engine is so much smoother, also pulls from 2k RPM now.
