Starting issue
 

Hi,
I noticed my bike was getting hard to start, from when I leave the house to get petrol for instance. Initially it'll start from cold no problem but if I switch off and then try to re-start it'll chug as if the battery is dying. So it seems it'lll start from cold no problem but then will immediately play up if switched off and re-started

Battery checked out 100%, I ran diagnostic and it threw two fault codes:

cam pulse generator
IAT sensor


Anyone have any idea which is most likely to have caused this fault? It has a PC111 fitted and a Remus pipe, always smelt rich to me from when I bought it but even more so now. From what I know 954's do run a tad rich anyhow.

No change in performance btw, runs like a bat out of hell
