AH ha! The saga continues!

Suggestions?

1) Check the battery. May sound stupid but it's easy and won't kill you to find out how it's working when hot and under load.

2) Any way to check their mapping?

3) Ask them to send you a carb conversion kit and airbox (if needed). EFI can be extremely tricky to sort out and you may spend countless hours and pounds helping them sort their EFI. Would be nice to at least have a fuel system that works.
