DTT BOTM WINNER
Hi all, Been absent for a while but wanted to start a thread for this build as I'm super excited about it. CB400F fully faired for the street. You just don't see enough vintage bikes on the street with fairings. I understand why; most bikes weren't faired for the street, actually none that I can think of until the 80's. ?? And those fairings are expensive. Plus most of us want to show off the beauty of the vintage motors and intake etc. I get it. CB400F is the perfect bike for this then. the motor is butt ugly and the rest of the lines, well, pedestrian. By adding a fairing it will make the one true design innovation on this bike pop. The first ever factory 4-1 exhaust. I found a fairing design that does not hide this but accentuates it.

I love this fairing design. It turns out that this pic is just a rendering and as far as I know this fairing has not actually been made. I'm going to make it or get it made. we'll see which.

First thing though is get the bike running and that starts with these shitty carbs.


Motor has good even compression so I'm going to clean the carbs and see what I've got before going any further. Unfortunately I am going to have to pull this rack all the way apart to get the job done. Im using a carb cleaner soak and then a bath in the ultrasonic cleaner.

Here we go!
 
Hey Justin! Nice to hear from you! Hope you are well. I'm psyched about this one! Leaning towards a dual headlight set up on it. Carbs are clean. waiting on rebuild kits for reassembly. We'll see if she'll fire!
 
All cleaned up and ready for new carb kits. which arrived in the mail just now. Should be able to try to fire her up this weekend.

 
maritme, when I'm done with this I will have at least a rolling chassis that you are welcome to. I may have a motor as well.
 
Need to up jet before I reassemble. Ran all over town and finally found a set of Micro drill bits so I can drill out the mains a couple sizes. more later. Mike, whatever I have left over is yours if you want it. !
 
Very cool! Would really like to see this build with that fairing. Are you going with glass or aluminum for the fairing? If aluminum, I would love to help you out with that.
Slick looking bike man!
 
I'm doing a full fairing kz400 right now for the same reason...Subscribed.
 
Love the fairing. Love ambitious builds. I'm currently going stupid all out on a kz400. Would love to see how the progress goes.
 
Okay got my jets drilled out two sizes over. decided to spend $15 on a micro drill kit instead of twenty on a set of jets. Where jetting is as much art as science this will allow me to keep playing with the jetting without laying out for jets and having ones i don't need at the other end. so Carbs are back together. I'll get them mounted and see what I have to do to the electrical to make this thing run.





In other unrelated news; anyone in the Portland, ME area want to go in on a shop? THis place is huge!
 
Cool. I would reccomend once you get the size nailed down by drilling to acutally buy the size from the store as the drilled jets aren't shaped as good as factory sized for flow, but drilling one size up at a time and running it is a good way to determine what you should run without spending $$ on 4 x each size X 5-6 sizes for sure.
