Help needed after Airbox Removal
Had the Airbox removed and AI done a few days ago by my local dealer who has done a few of these. My bike is a 2009 Bonny T100 EFI with twin Staintune pipes.
On taking it home, I found the difference noticeable immediately, however when approaching slow corners or in a roundabout in first gear, if I'm feathering the clutch / throttle the bike starts to stutter and actually stalled for a millisecond a few times which was quite disconcerting as I was leaned over at the time.
I took it back and they didn't feel anything was wrong but tried a different map. The same problem exists and now the bike backfires a lot and if after a high rev in 3rd or 4th it backfires and then rocks backwards and forwards on the way down.
When it is idling, it sounds OK however every 4 - 5 seconds it seems to drop a rev if that makes sense. There is also a loud 'tock' sound from around the cam covers too in the same time pattern.
Before I take it back to the shop (who are very helpful BTW) I wondered if there is anything I should advise them to consider?
