OK, just got in now, going to answer a few questions.
The secondary tank is in very good shape.
I'm going custom with this bike, going to be like a bar hopper just for fun on short trips, so less fuel not an issue.
I have a larger bike for longer trips
Already removed the air box and installed pods and and bigger jets.
Removed the ugly rear fender and all the electrics are inside a custom box next to the battery.
Removed the rear tank that's why the question about the venting.
Made a lower custom seat with the same seat pan.
Re- bend the handlebar and now looks like mini apes
Very fun driving machine.
I'm doing all this because the bike was not original when I got it.
I don't have pictures yet because is not finished
