subscribed mr Geek, this looks like a top notch build job in the making. Looks like a top notch shop space as well.
I tore open my brand spanking new (350) EXC on Sunday, appears to be about at the same step as you.
here's the exc wire mess up front to compare, not too bad, no jumpers...
looks like similar hdb stabilizer setup from paul (minus anodized), 1 5/8" rise over stock.
yep, advantage goes to xc-w model, no need to remove any of the emission stuff. Although charcoal canister and bits came off in very short order. SAS removal is another story.
