One of these hubs is intended for this bike too. I am thinking to take the rusted chrome steel wheels I end up with after I am done upgrading wheels for the K2 and sandblast and paint them, and assemble with new spokes. Balancing recycling something that still has usable life with some work..or buying something already shiny LOL. These hubs will get vapor blasted now.

[willbird]

These are now vapor blasted, one or more PO have of course had their way with them over the years.

Finally got the last exhaust spigot off today. 6 screws came out fairly OK, the last two were more difficult. I had drilled a 1/16" hole right up the middle of the one to try getting some Kroil into the back end of it. No joy there. Lit up the American Oxy-Acet hot wrench with a small rosebud tip and made the end of the flathead screws red warm briefly and then they came out with hammer type impact screwdriver.

Took original forks apart, one had the upper cap off last 20 years so suspected it was trashed, surprised it came apart. the steel piston acted like a sacrificial anode I guess, saved the lower. Fork oil mixed with rainwater aged for 20 years is an olfactory treat :-). Had bought a pair of forks from ebay that working portions of tubes were good, stripped those too. took triple trees off and took all that stuff to be blasted. bead blast on lowers to be followed by vapor blast, just bead blast on triple trees, will paint those. tossed the chrome headlight mounting ears in a 5 gallon bucket of evapo rust, sunk half the front fender in there too. knocked the loose balls races out of the frame. I have a green box 1990’s NOS tapered roller bearing set to go in there

Latest stuff back from glass bead and or vapor blast.

This was glass bead then vapor blast, the pivot pin was just vapor blast.


These I asked him to glass bead and then vapor blast, they were really nasty to begin with and had patchy clear coat remaining.





This stuff was straight up glass bead blast because I am going to repaint them.

I have a spare set of lowers too, thought about posting them for sale on the site. Not sure what fair price is for them done like this, possibly on an exchange basis. I will have stainless nuts for them, and stainless drain bolts, and new copper washers. I grabbed a whole extra set of forks because I was not sure anything from my original ones would be salvageable. Turns out the lowers were fine.

Dropped this off for sand blasting today



Decided to make a frame kit for it and that pretty much requires removing the engine to weld it in. So at this stage I guess getting the frame cleaned up makes sense.

Bill….. Good stuff. You going to paint fork lowers? I did the ones on the Benelli, using the same paint I use on my cb engines.  They always looked great and didn’t need to be “maintained”!

I'm not sure honestly. My original plan was to focus on function and ignore appearance for the most part, but paying a nominal fee so far for vapor blasting has been an efficient way to clean things up. My best guess is to not paint them, just use Sharkhide. I have in the minds eye to do the frame with this color here, a flat finish single stage urethane OD green, and then do body in a dead flat black urethane.

Not sure on fenders...I saw a post where a guy showed how he removed the welds on the rear fender bracket, rotated forward and then re attached the bracket, then used a Lucas tail light, that looked pretty sharp.

Just not sure if that fender should be chrome with a chrome light, chrome with a black light, flat black with a chrome light :-).

Kinda leaning towards chrome because I have a front one that cleaned up decent after a bath in evaporust. So that leaves me to pick chrome or black lucas light. I'd suppose the headlight brackets remain chrome too. Those might balance well with blasted aluminum lowers.

I had thought about finding some kind of frame mount quarter fairing but a few searches have not given me any clues. Never been a fan of fork mounted fairings.

[HondaMan]

(Can I ask?)...if you come across a Vetter Quicksilver for a decent $$ in your search, could you PM me?

I need one for my upcoming CB350F resto.

I see folks have put them on CB750K as well, have not run into one yet though. I rode a CB450 around the mile square many years ago that had a Windjammer on it, wayyy too much fairing for that bike.

Cannot beat 24 hour turn around :-).

Wow!

Wow!

That metal has not seen the sun since 1972-73 LOL.

If I were that frame, I'd feel naked!
I agree about the 'Jammer and the 450 being overkill. But, in the era of the 1970s, it was also the only practical frame-mounted fairing: we were installing them on CB350 twins and CB350F bikes and more than 1 were on the Yamaha 350 twin 2-strokers in the college town where I had my shop. I saw one on a 305 Dream Honda, but he had to have made his own frame mount (and where?) as Craig didn't make the 'Jammer for any bikes smaller than the CB350 Twin and Four in those days. The Quicksilver was originally intended for those smaller bikes but it caught an edge into the "looks" category and showed up on customized bikes right off. That wasn't what was planned, but it built a niche that way. It's a nice fairing for guys like me who got tired of hanging onto the handlebars at [real] interstate speeds, which are now back again.

An interesting view into Craig Vetter: my Honda mentor Jim Chamberlain and he were tight, and when Craig made the first Phantom for the 750 he called on Jim for testing, who toured between central Illinois and his folk's home in upstate New York (in all 4 seasons!) on his Bridgestone 175 twin, of which Craig also had at his shop: Craig made the first Phantom for his own Bridgestone, and my friend Jim got the other one. There were only 2 of those, handmade, as prototypes for the Phantom for the 750. They were ridden for 11 months in all 4 seasons for testing: Jim went from Peoria, IL to upstate NY for Christmas Break in 1969, with that fairing. He came back and bought the shop's (where we worked) first sandcast 750 after that, and got Phantom #4, I think it was (Craig's was #2), as the fairing. Phantom#1 was broken up after the wind tunnel testing at the IL Champagne-Urbana wind tunnel showed it needed minor mods, leading the way into Craig's own. His 1972 Suzy waterbike became his own use of the Windjammer (I) we all know today, and most early pictures of him show that bike. He was said to have designed lowers for the Quicksilver, but only a few were built and sold, and I don't think his company made them. Talk about rare parts...

Mark,I have a Quicksilver complete with bracket to fit the CB400F.
PM me if interested.

Got the Eastwood epoxy primer laid onto everything. The sandblast shop said to get primer on it pronto.

I listed this project for sale as in the for sale forum, if it is not appropriate to mention that here and link to the ad  please advise and I will modify this post immediately.

Good project and very fair price.  Just curious - why you selling?

My intention with this was to put a MicroSquirt fuel injection on it with crank trigger ignition, get that all worked out then drop it on my K2 whiich was my only working motorcycle. I bought a new CB500X so now that puts the K2 into the "project bike" spot really, and one project is enough for me honestly. So now I can explore the modern engine control stuff on the K2 maybe and still have a bike to ride while I am doing it :-). It is also in a good spot for the purists that hate to see a frame cut because I had intended to do a frame kit on it to be able to do engine upgrades after it had gone into the frame without taking it back out. I did make up most of a frame kit that somebody could have with it too if they want...I posted pics on another thread and people were digging on it.

 If you still have the trans cover check the stud that holds the springs and rollers, I had one with a loose thread. That bike would fall from neutral into gear when kick starting. (It was kick only back then) It turned out to already have a heli-coil but the stud threads were worn so I swapped it for a new one with red loctite.
