Carb teardown, by the book
Morning session with the shop manual open to page 4-9. Both carbs fully apart, laid out on the tray, and the first cleaning pass.
Coffee, then the manual. Last night was enthusiasm; this morning was procedure.
The shop manual’s carburetor section (page 4-9 and thereabouts) has the exploded views you need, and I photographed the pages I kept flipping back to so they’d be here with the parts photos. Once the manual is scanned into the library they’ll be searchable, but for now the photos do the job.
Layout
The red tray in the photos is how I kept two nearly identical carburetors from getting mixed up: secondary in the top half, primary in the bottom, each one’s screws and jets in the compartment next to it. It sounds obvious. It is also the step that people skip and regret.
Cleaning
First pass today was carb cleaner, a brass brush and compressed air. Jets held up to the light until I could see through them. The jet needle got cleaned by hand, gently, because scratching the taper changes how the bike runs at mid-throttle.
After lunch the tank came off. That’s the next entry.
