i'm not smart nuff so i'd never bother doing it, but you could have a crack at designing something so the fairing is an optional element. ie. the overall design will work both naked as well as with the fairing. i've seen some japanese folks do this really well.
that thing looks so nice that it's kind of a shame to completely leave it behind.

i think the grey and beige colour scheme on your first concept it really nice too

fairing would be cool if you used one of those long squarish small tanks I think they are off of a honda cr

faring would surely be cool.....if you do find one, have fiberglass molds made, and make your money back selling the ones you make.


Put me on the list.

Got the fairing (as shown in the first few pics), thing is, most people who have said they want the fairing or a copy of it are from America, so buy the time I put in time to make copies and then ship to america, its really gonna push the price up...

Yeah I agree actually, make it look like a proper vintage racer, but they cost quite a bit and am a bit stuck for funds at the minute :-\...I do like the look of the current tank on it aswell, I think its from a cb550, not sure....hell, If I can flog a couple of fairings in the UK I may be able to pay for one  ;) haha

Anybody able to move this into the build thread section?

Got started on the bike today, battery was flat so its currently on charge  :-\ . Will get a video of it running as soon as.
Took the fairing off to see how it looks. The headlight mounts directly onto the fairing so i've had to cable tie it on to the forks for the minute to see if it looks alright, then I'll pick up some proper mounts.

Took the header and mufflers off to give them a decent clean. Collars are being cleaned at the moment aswell, may give them a lick of paint if I can decide on a scheme for the motor.

Anyway, pictures!  ;D  haha...I like the stance of the bike as it is to be honest, but may lower the front an inch or two...any thoughts? (Sorry about the poor quality, was taken at 10pm in a poorly lit garage with a laptop camera haha)

Hi, get the fairing back on!!! Not often you find one with as good lines as the one you have. I think you should go with your original colour scheme on the jacket, it would look similair to the one in that perfume advert? You know the chanel' one with Keira Knightly, think it's a Guzzi though..
By the way I think I am just over the bridge from you.  :)

It's a Ducati SS Bevel !
But the manufacturing land was right ;)

And I dig wab's opinion !
Your fairing is badass, keep it on and do a vintage racer style it definitly will look superb !
But it's just my opinion, as long as you enjoy building and riding everything will be fine ;)

Looks pretty sweet with the fairing on there, man. I'd keep it for sure :)

That's the direction I want to go with my CB175, full vintage racer setup. Did you weld up your own mounts for the fairing or manage to bolt it on somehow?

Yeah, I saw that and started looking at a beige/cream theme, then found the jacket. I'm gonna spray it grey to start seeing as I already have the paint, and if it doesn't look right i'm definitely going to go for the scheme on the jacket  8). Ah yes you are just over the bridge, not too many active UK members on here let alone local haha.

The mounts are bolted. on. The rear mounts connect to the base of the battery box and front is clamped and bolted to the downtube.

Not much to report at the minute. For some reason its just lost spark so no starting her up for the minute. Between a slight cross-threaded head and a clusterfuck of dodgy wires and connections, this is gonna take some time  >:( haha.

a-ha! (As Mr. Alan Partridge would say). The lack of spark issue may have been solved. Could of diagnosed the problem quicker if I could find my multi-meter, but it seems to be the left side coil. So another one is on its way.

Apart from that, I replaced most of the bolts I could undo (Most are extremely rounded and an absolute b*****d to undo) with stainless allen head bolts, and Ive primed the carb tops.

Also wheeled the bike out into the sunshine to get a better picture as it currently sits :).

Ok, Im not great with bikes so i'm gonna need a bit of help here.

Sorted out the wiring and coils so now she starts and idles. The idle is pretty inconsistent as it seems to occasionally rev itself and then slow down. Once the throttle is twisted, the bike dies. But this is only for the left carb (when I use move the throttle arm on the right carb it revs fine, but on the left, it dies)...Is this just a sync or timing issue...maybe throwing too much fuel in from the left side?
