SixtyNine!

I'm going to start a build blog covering SixtyNine... actually, I guess I just did.

I don't know how this is going to go because I'm kind of all over the place with this bike. I'm trying to finish my car... and my other car so that I can have something other than my Fiancées car to drive when it rains (or at least so that I can sell one and get myself a van :) )

If there's anyone out there that hasn't seen my concept rendering for it:

So I call it a race replica... but I think it's still a cafe. It'll have lights and a plate and all that legal stuff, and mirrors... real mirrors! I really like mirrors on faired bikes for some reason, adds to the upside down triangular shape I think (ala 916,748,996) I've always thought full faired bikes without mirrors looked in some way neutered.

I've tried to digitize the frame in the past and failed pretty resoundingly. I could have used the CJ frame that Chris had to cut it all up, scan it and try again... but he threw it in the trash before I thought to ask for it :(

the point of digitizing it would have been to use that data to build the fairing on top of... something I don't know how to do but was willing to try. Starting that over.

I've torn the engine down (so far save the bottom case) and am going to go with what I've come to call the "PJ route". I bought a pair of NOS GS850 pistons and will somehow bore the thing out to fit. This bike is all about tweaking it out to the max that I'm capable of. I'm not a motor guy but again, I'm willing to try. Plans call for deburring and polishing the con rods, shaving and polishing the rockers, port and polish for the head, at least lapping the valves, recutting them and installing brass guides if I can figure out how. I'm starting with a CL so I'll be swapping for a CB gearset. Prettying the motor up and chopping a bunch of crap off of it.

Composites will be used for all the body work including the tank and tail.

Hopefully at the end of this already long road I'll have what in my mind represents the ultimate street 360 as an interesting comparison to Loudbike which is much more stock when it comes to the motor.

I anticipate this thread moving along at a leisurely pace because really I'm not supposed to be working on this bike at all until my cars are working properly or gone all together, maybe you guys can help this move along. If anyone really wants to help they can buy one of my cars!
 
I cant tell you the # of times ive stared at that rendering on your webpage... Goddamn do I love the look of that thing!!!
 
the first day

she's a looker!

She was dubbed SixtyNine thanks to the last two digests in her engine vin bing 69, and with a name like that it was going to have to be a race style bike.

Tried at one point to block out the fairing using painters tape:

...lots of painters tape. FAIL!

Carved up the drum a bit:

that was mostly successful
 
Found more pictures of the huge mess I made:

I hate this stuff, i spent several days shaping and carving... but it doesn't keep its shape
 
You know the MH900e? I love the clock on that thing, and I'm going to do something similar (but all analog) with this bike

disregard the Classic Instruments catalog in the background, this will all be hand built by me

my first try at a face:

Graphic designers out there... I want your' help with this. I'm hardly thrilled with the stuff I've come up with so far.
 
what is the diameter of the clock? I'll whip up a few ideas at work tomorrow... The 69... can't beat that! I've always wanted a vintage fairing bike!
Makes me want to build one!

Try adding some bamboo skewers in as you build up the foam. It will stiffen it up. cross them in each layer. also, the "minimum expanding" tends to flex less. you have to buy more, but it has less air in the expansion. you can start with that and then work up to the big gap stuff.

It may not look it, but a lot of time has gone into this top end, deburring and reshaping, and it's far from done. Don't ask me to tell you why I do it, anyone who asks wont understand the answer.

It's actually kind of satisfying thinking about the fact that with every stroke of the file the bike is just a little bit lighter.

Ahh, good tip. I was pretty much done with that junk, but maybe I can give it a second chance. I'm not doing it on Loudbike again though. It'll have to wait for SixtyNine to reach rolling stage.
 
Forget painters tape, here's how to do the fairing (you know....on a budget...)

Design bodywork:

Produce sexy finished product ;D

I was wondering when the dust would get knocked off of this one! Thank god it has begun. I've got a fairing or two sitting here too. My favorite of which is a Ducati 900ss that I have to repair (a friend had it on a Thruxton and wrecked it and gave me said $600 fairing and mounting hardware for free) Still wondering what to use it for...

Congrats on getting the thread started. ;)

I like the filed jugs. That's a great idea. Sand casting is cool but it leaves an ugly part behind.
 
Awesome build. Attention to detail is where its at. Keep it up.
You could always do the fairing with short pieces of wire and hot glue the John Britten way. Remember this one

I thought this was going to proceed at a "leisurely pace" ;D

Loving it so far Kit, really looking forward to watching you work through this one. Your last bike is definitely one of my favorites so this should be good.

...from now on. Everything I've posted is quite old, it was piling up, hence this thread. Let the leisurely pace begin.
