So, it's all done! Had it out for a ride yesterday. It ran great!!! Checked the compression and all cylinders now are at 155-160, big improvement from before rebuild, had two back ones with 0. Now big question, what to do with the vboost switch? It seems to idle faster when switch is to the right, center and left seem to be normal or off? Any ideas on what to do with it or how to check if it is working correctly?
Does the switch make the VBoost work differently? Try this:
Remove the left scoop, locate the round plug to the stepper motor for the VBoost. Turn on the ignition, and when the VBoost cycles open,
and before it can close, unplug the electrical connection. Compare the idle, and the performance to the VBoost while underway, to how the bike idles, and how the bike reacts with the switch in different positions. maybe use your cellphone to record your impressions for each circumstance.
Does the VBoost not kick-in at-all (because it's unplugged, and the VBoost butterflies are always-open)? This will give you that "cammed V8" sound, especially at idle.
Does the VBoost come-in gradually from 6000-7000 rpm? That's the normal function.
Does the VBoost come-in at around 3000 rpm, but the 'push in the back' isn't as-extreme as it is at the 6000-7000 rpm range as the VBoost begins to open and then is fully-open?
Once that experimentation is completed, you can either choose to keep it as it is, wired-in, to play with the settings (pulling into the Bike Night place, switch the VBoost to 'all the time, open' for that great idle sound) to leaving it in the factory setting, where it begins to open the VBoost manifold past 6000 rpm. Or, the 3000 rpm opening setting.
