It’s a Yamaha bike! The design is pretty old, you know—”this thing’s gonna slip”—or rather, the starter clutch
structure is old. Same as the Z and GS models—the M8 bolt-down type! It loosens up, doesn’t it?
So I thought I’d take it off, but… our tools won’t do it! Hmm, even if I bought the tool, I’ll probably never
do this again! A VMAX or something…
Well, can’t be helped! Let’s make a simple one—
So I took T=5mm 2017 aluminum, cut it on the contour machine, drilled a 12.5mm hole in the center and 120° × 3
38mm with three holes (8.5mm each), for a total of four holes to make a simple puller!
It came right off…. Most of the time went into making the tool and scraping off the gasket….
