Of course, original Seca exhaust sytems are about as common as hen's teeth, and the few aftermarket systems still out there were not quite what he wanted. So we acquired some stainless exhaust tubing, scavenged the headers from the Maxim and the baffles from a 750 Wolf set and built our own.
Time for some serious overhaulin'. A low mileage replacement mill from a Maxim 650 was located. Of course, to fit the rubber-mounted Maxim engine necessitated some frame modifications. And of course, the Seca's mechanical tach wasn't of much use anymore, so the Maxim Dash was grafted into place. Couldn't give up that massive Seca headlight though, and so it was retrofitted with a 100 watt H4, augmented by a 35 watt H3 driving light discretely mounted between the forks.  Other changes include moving the turn signals to the Maxim mounts, new wheel bearings, recovering the seat and rejetting to suit the exhaust.
Many moons ago, #3 son bought a near-mint XJ650 Seca. Many miles and 1 accident later, it began to show it's age. Compression was down, puffs of blue followed like a cheap perfume, the speedometer was erratic on a good day and the 4-1 exhaust precluded fitment of a centre stand.
With the running gear sorted, it was time for some cosmetic work. The dented tank was purged, charged with 5psi of argon and dents gently heated, allowing the internal pressure to ease them out. Standard bodywork techniques followed to perfect the curves and it was off to the paint booth! Well, paint tent actually. 2 coats of dark grey metallic base coat were given a very discrete -- almost stealthy -- graphics treatment before 9 coats of hand-rubbed acrylic urethane clear. The graphics disappear and reappear depending on how the light hits them.
