Absolutely top notch work.
Am I allowed to put some input in? ( I know I am new, but I've built so many custom bikes it's silly!)
I was going to mention the chain but was pipped to the post on that one!
The airbox on the Honda has to come out before the engine and carbs can be removed, so that would normally be sitting outside the frame.
The other thing Is, the throttle cables are normally removed from the carb end when doing engine out work, and left ha going from the handlebars. It's easier to undo two nuts and remove the cable at the carb than it is to undo the whole right hand switchgear, disconnect the cable, then unthread it while trying to remove the engine.
Don't shout at me, as that's NOT criticism on your model. Just what we do in real life.
I LOVE the toolbox and the small posters, where on earth did you get them??
