No more BST!
Ok, I finally decided to just take the plunge and inject my 640 ADV.
So far I've got a Megasquirt fuel injection computer, a few Audi injectors, a bunch of bosch connectors, a VW vanagon fuel pump and a nice new O2 sensor.
So far the missing link is a left side t-body from a BMW boxer bike (TPS sensor) that I need help finding.
After farting around with the carb I realized how much better the ADV would be if it had smooth consistent power all over the rev range, and at all altitudes. Worth documenting? Anyone else interested? If this works, maybe the next step is to turbo a 640e and make it a Super Duke eater? Ahh I love a good winter project.
