Yes, generally US Suzuki manuals have routing diagrams for the California charcoal canister but I wanted to avoid buying one for just this purpose, because I already have Inazuma service & user electronic manuals, and I'm cheap.
I have been looking at diagrams for other Suzuki models, and the parts diagrams for the GW250 are helping a bit. I will probably be able to piece it together using some deep thinking. :)
Again, thanks to all.
