Yamaha Seca II
This bike started as a 1992 Yamaha Seca II, a well-known 600cc all-arounder. I bought it for about $1100, in decent shape.

Here’s roughly the order of operations for the redo. It took a couple of months of late evenings and early weekend mornings before the kids wake up:
- Complete teardown, everything but pulling the motor apart; got rid of all plastics, fairing, clocks, signals, lights, everything
- Trim a bunch of excess brackets and such off of the frame with a grinder, chop about 4 inches of useless metal off the tail
- Sand, paint frame with Herculiner
- Sand, prime, and paint swingarm with Duplicolor bedliner
- Fabricate “body panels” out of Home Depot aluminum diamondplate (pretty thick, dunno exact); used a recip saw with a sheet metal blades, a bench grinder for some edges, a vice to do the bends, and a drill of course; primed and painted with Krylon; panels are mounted to the frame with U bolts and pipe clamps
- Rear fender plastic trimmed up, license plate mounted to underside
- Tank sanded down completely, primed and painted with Duplicolor; valve reseated; filler cap cleaned up
- Cleaned up all motor surfaces, replaced all hoses
- Complete carb clean (not very well probably)
- Re-wrapped and cleaned up all wiring harnesses; re-routed all wiring near the motor
- Mounted Aztc8 dual 7 inch lights with provided brackets but using generic clamps on fork tubes (better than the plastic ones provided with the lights)
- Wired in new headlights, signals, including adjustable LED flasher relay that does fancy blink patterns, and tail (from a trailer)
- Rebuilt switchgear, lubed up, painted plastic housings
- CRG hindsight barend mirrors
- New grips
- New bar (Yamaha style)
- Painted all triple clamp pieces, bar mounts, lever bosses, anything not black, with black caliper paint
- Wired in GPS mount (easy, just a +12 and GND) and Acewell gauge cluster (not hard, just a lot more wiring)
- Reupholstered seat at a local shop
- Powdercoated fork lowers, rearsets, and wheels at local shop
- Rebuilt forks with new oil and bushings, springs were ok
- Remounted tires and replaced all bearings (incl in hub)
- Put it all back together, more or less as it was supposed to go
Here’s a slideshow of what it looks like now:
Next-up:
- Exhaust (probably going to chop the cans in half and then repaint, to give it a bit more noise and a different look (less respectable))
- Few motor fixups, including gasket replacement and hopefully an end to a few small but persistent oil leaks
- Probably need to replace the steering head bearings, not the smoothest
- Still need to do a brake refurb
